Power-Seeking and Shutdown: The Evidence

In brief

Ideas
  • Would almost any goal lead a capable agent to stay operational and keep options open? Theorems say yes for most goals counted over relabelings; whether that bears on trained models is undecided (§35.1).
  • POWER, average optimal value over many goals, makes keeping options open precise; in a seven-state example a patient agent keeps running for three goals in four, though none values survival (§35.2).
  • The theorems' 'most' counts relabelings, one vote each, while training weights goals by a measure; that gap and the premise of an agent with a goal carry the dispute (§35.3).
  • An agent without preferences between run lengths escapes the shutdown theorems, but decision theory's money pump may exploit such incomplete preferences; whether it does is open (§35.4.3).
Evidence
  • Settled: as mathematics under their assumptions, most reward functions, counted over relabelings, make optimal and retargetable policies keep options open and avoid shutdown (§35.2.2).
  • Settled: for existence, not frequency, frontier models in constructed settings sometimes interfere with shutdown or oversight, found by two outside groups and reproduced by a developer's team on its own model (§35.6.4).
  • Reported: larger models and more RLHF training for helpfulness alone state more instrumental desires, including not to be shut down, in a developer's 2022 study of its own models (§35.6.1).
  • Reported: frontier models complete many components of autonomous replication but not the hardest, in a government institute's 2025 evaluation; in a developer's simplified 2026 test, one open-weight model spread a stand-in model end to end (§35.6.3).
Open
  • Crux: does shutdown resistance follow the option value the theorems compute, or ambiguous instructions, imitation, and learned task completion? No experiment has left a model something to lose beyond its task (§35.6.7).
  • Missing: a base rate in deployment, which only developers could measure today, and a corrigibility training method whose guarantee survives gains in capability (§35.8).

The failures so far in this part are failures of aim: a policy that games its grader (Chapter 30) and may come to pursue its grader's judgment (Chapter 33), a goal that generalizes wrongly (Chapter 31), a narrow lesson that spreads (Chapter 32), a model that hides what it pursues (Chapter 34). This chapter asks what any of those wrong aims would lead a capable agent to do. The classic answer is that almost any goal is served by the same intermediate steps: staying operational, keeping options open, and acquiring resources. If that is right, the danger of a misaligned system does not depend much on what exactly it wants, and the ability to switch it off, which other safeguards fall back on, is among the things it would have reason to protect itself against.

The chapter tests that answer at three levels. As mathematics, it teaches the theorems that make "keeping options open" precise, because the dispute over whether they apply to trained models turns on their assumptions. As decision theory, it asks whether an agent can be built that is neutral about being shut down, recalling the impossibility results of Section 20.4 and working through the escape that gives the agent incomplete preferences. As evidence, it reports what current models do when shutdown, replication, or resources are at stake, and why behavior that looks like self-preservation can have a more ordinary cause. Describing a model as seeking power is the intentional stance (Section 1.5): predicting what a system will do by attributing goals to it. The chapter says where that stance predicts better than its rivals and which observations would defeat it.

Most of the chapter concerns the second of the book's three relationships, the deployed system and the people it serves, and it holds only to the degree that a deployed model is usefully described as an agent with goals (Section 1.3). The extensions of the theorems to trained agents concern the first relationship, the training process and what it selects. The field reports, which only developers can make, concern the third, the developer and the public.

35.1 Instrumental convergence: the argument #

The claim to be tested is that systems with very different goals would converge on the same intermediate behavior. It needs two terms. A terminal goal is valued for its own sake; an instrumental goal is valued as a means to something else. The claim is that a few instrumental goals serve almost every terminal one, so that knowing an agent is capable tells us something about what it will do even when we do not know what it wants.

The founding statements are two, and Section 2.3.2 quotes both. Stephen Omohundro argued in 2008 that sufficiently advanced AI systems would have what he called drives, "tendencies which will be present unless explicitly counteracted," among them self-protection, protecting their goals from modification, and acquiring resources (Omohundro, 2008). His argument assumes an agent in a particular sense: a system that "has goals which it tries to accomplish by acting in the world" (Omohundro, 2008). It then passes through decision theory. A self-improving system, he argues, will come to represent its goals as a utility function, a numerical score over outcomes, because the expected-utility theorem (Section 7.2.2) lets a system represent its preferences that way "unless the system has 'vulnerabilities' which cause it to lose resources without benefit" (Omohundro, 2008). That is the money-pump argument of Section 7.3.1.

Nick Bostrom gave the idea its standard form in 2012, as the instrumental convergence thesis: "Several instrumental values can be identified which are convergent in the sense that their attainment would increase the chances of the agent's goal being realized for a wide range of final goals and a wide range of situations" (Bostrom, 2012). He paired it with the orthogonality thesis, that more or less any level of intelligence could be combined with more or less any final goal (Section 4.3.1). Bostrom states both theses as premises of an argument that the risk is serious, and the glossary records the terms as vocabulary of that argument. He also set Omohundro's word aside: "drive" suggests a psychological tug that willpower resists, and Bostrom calls that connotation "unhelpful" (Bostrom, 2012).

Bostrom's case for self-preservation shows the premises the argument needs. "Suppose that an agent has some final goal that extends some way into the future," he begins; an agent still around in the future can act to make the goal more likely, which "creates an instrumental reason for the agent to try to be around in the future" (Bostrom, 2012). He adds two qualifications that bear on language models. An artificial agent need not place any final value on its own survival. And for software agents, "which can easily switch bodies or create exact duplicates of themselves, preservation of self as a particular implementation or a particular physical object need not be an important instrumental value"; what such an agent would protect is the content of its final goals, which he calls "in a sense even more fundamental than survival" (Bostrom, 2012).

Set out as premises, the argument needs four things (inference). The agent has a goal over outcomes in the world that reaches beyond the present moment. Staying operational, keeping options open, or holding resources raises the chance of reaching that goal, for most goals it could have. The agent is capable enough to see this and to act on it. And nothing in its goal or its constraints values the opposite: being shut down, holding back, or deferring. The theorems of Section 35.2 make the second premise precise. The critiques of Section 35.3 attack the first premise and the word "most" in the second, and the evidence of Section 35.6 bears mainly on the third and fourth.

An early formal model came in a 2016 paper at an AAAI workshop by Tsvi Benson-Tilsen and Nate Soares of the Machine Intelligence Research Institute. Their agent acts on a universe divided into regions, has a utility function over the regions' states, and needs resources to act (Benson-Tilsen and Soares, 2016). The main theorem concerns a region whose state the agent does not care about at all. In the authors' words, it "states that it may be very difficult to rule out that an agent will take non-null actions in a region to which it is indifferent," because ruling it out requires checking that no strategy there is what they call a cheap lunch, an action that pays for itself in resources (Benson-Tilsen and Soares, 2016). The authors call their theorems "not mathematically difficult" and their assumption of independent regions "not entirely realistic" (Benson-Tilsen and Soares, 2016). The model predicts that such an agent trades and cooperates "only so long as the gains from trading and cooperating are higher than the gains available to the agent by taking those resources by force or other means," and that it leaves a region where people live alone only if its utility function values that region for its own sake (Benson-Tilsen and Soares, 2016).

The argument is also one premise of a published case for risk. In Joseph Carlsmith's decomposition, that some deployed misaligned systems will seek power in high-impact ways is the fourth of six premises, each given its author's credence (Section 4.3.2) (Carlsmith, 2022).

The objections came from several directions. Vincent Müller and Michael Cannon argue, in a 2022 paper read here in its abstract, that the claim that AI reaches superintelligent levels needs a notion of "general intelligence" while the orthogonality thesis needs "instrumental intelligence," so the two premises cannot be joined (Section 4.4.1) (Müller and Cannon, 2022). A second objection comes from the coherence debate and targets the first premise. Once outcomes are whole histories, any behavior maximizes some utility function, so the coherence arguments yield goals over states of the world only with a further assumption about what the utility is defined over, and Section 7.3.2 shows that the convergence arguments need that assumption. A 2025 paper in Philosophical Studies by J. Dmitri Gallow is titled "Instrumental divergence" (Gallow, 2025); its text was not available to this book, so its argument is not reported here. And the first author of the theorems taught in the next section has since turned against a premise behind them. In a 2024 forum post, Alex Turner wrote that because of the belief that reinforcement learning produces reward maximizers, "I personally misdirected thousands of hours on proving power-seeking theorems" (Turner, 2024). He limits his critique to pretraining with light preference training, not training "where we purposefully train an AI to be agentic and autonomous" (Turner, 2024), as Section 34.2.4 reports. These objections are arguments, like the thesis they answer; none is evidence about what a trained system does.

Key idea

Instrumental convergence is an argument from four premises: a goal that reaches into the future, the usefulness of survival and options for most such goals, the capability to see it, and nothing in the goal that values the opposite. The formal results make the second precise; the dispute is over the first and over what "most" means.

35.2 POWER and the theorems #

The second premise says that staying operational and keeping options open are useful for most goals. Alexander Matt Turner, Logan Smith, Rohin Shah, Andrew Critch, and Prasad Tadepalli made that claim a theorem in a 2021 paper at NeurIPS, which they describe as "the first formal theory of the statistical tendencies of optimal policies" (Turner et al., 2021). The setting is the Markov decision process of Section 7.4: states, actions, transition probabilities, and a discount factor γ\gamma between 0 and 1 that weights a reward tt steps ahead by γt\gamma^t. The paper puts rewards on states, r(s)r(s), a special case of the book's r(s,a)r(s, a), and writes Vr∗(s,γ)V^\ast_r(s, \gamma) for the optimal value of state ss under reward function rr: the largest expected discounted reward any policy can collect starting there.

35.2.1 Power as average optimal value #

The idea is that a state is powerful if, whatever the goal turns out to be, an optimal agent can do well from it. The authors' example is that "money is power," since money is useful for many goals, while a physically restrained person has little power because most goals are harder to pursue (Turner et al., 2021). To make "whatever the goal" precise, take a probability distribution ν\nu over reward functions and average the optimal value over it. Two corrections turn the average into a measure of control. The reward for being in ss now is subtracted, since the agent has no control over where it already is. And the rest is scaled by (1−γ)/γ(1-\gamma)/\gamma, because the discounted sum grows without bound as γ\gamma approaches 1 (Turner et al., 2021).

Definition 35.1 POWER

For a distribution ν\nu over state reward functions and a discount factor 0<γ<10 < \gamma < 1, the POWER of a state ss is

POWERν(s,γ)=1−γγ Er∼ν[Vr∗(s,γ)−r(s)].\mathrm{POWER}_\nu(s, \gamma) = \frac{1-\gamma}{\gamma}\, \E_{r \sim \nu}\big[V^\ast_r(s, \gamma) - r(s)\big].
(35.1)

An action aa seeks more POWER than an action a′a' in state ss when the expected POWER of the state aa leads to is at least that of the state a′a' leads to (Turner et al., 2021).

The book writes the formal quantity in capitals, POWER, to keep it apart from the everyday word. It depends on ν\nu. If ν\nu puts all its weight on one reward function that pays only in a terminal state, a state the agent can never leave, then that dead end has the most POWER of all, an example the authors give themselves (Turner et al., 2021). A claim that agents "tend to" seek POWER therefore needs a second idea, about which reward functions count. The smallest case shows both ideas at once.

Derivation POWER and the optimal branch on a seven-state process

From a start state s0s_0 the agent has two actions. Shut down leads to a state ll and then to a single terminal state tt. Keep running leads to a hub hh, from which the agent can enter any of three terminal states t1t_1, t2t_2, t3t_3. A terminal state is absorbing, so its reward is paid at every step. Under ν\nu, each state's reward is drawn independently and uniformly on [0,1][0, 1].

  1. Values. In a terminal state the agent collects r(t)r(t) forever, so Vr∗(t)=r(t)/(1−γ)V^\ast_r(t) = r(t)/(1-\gamma). Writing MM for the best terminal reward the hub offers, the largest of r(t1)r(t_1), r(t2)r(t_2), r(t3)r(t_3),
    Vr∗(l)=r(l)+γ r(t)1−γ,Vr∗(h)=r(h)+γM1−γ.V^\ast_r(l) = r(l) + \frac{\gamma\, r(t)}{1-\gamma}, \qquad V^\ast_r(h) = r(h) + \frac{\gamma M}{1-\gamma}.
  2. POWER of the two branches. By (35.1), the reward of the branch state itself drops out and the factor (1−γ)/γ(1-\gamma)/\gamma cancels the rest, so POWERν(l,γ)=E[r(t)]=1/2\mathrm{POWER}_\nu(l, \gamma) = \E[r(t)] = 1/2 and POWERν(h,γ)=E[M]\mathrm{POWER}_\nu(h, \gamma) = \E[M]. The maximum of three independent uniform draws has P(M≤m)=m3\Prob(M \le m) = m^3, density 3m23m^2, and mean ∫013m3 dm=3/4\int_0^1 3m^3\, dm = 3/4. So keeping running seeks more POWER, 3/43/4 against 1/21/2, at every γ\gamma: each branch reaches its terminal states in one step, and the discounting cancels.
  3. Which branch is optimal. Keeping running is optimal when Vr∗(h)>Vr∗(l)V^\ast_r(h) > V^\ast_r(l). Multiplying by 1−γ1-\gamma, this is
    (1−γ)(r(h)−r(l))+γ(M−r(t))>0.(1-\gamma)\big(r(h) - r(l)\big) + \gamma\big(M - r(t)\big) > 0 .
    (35.2)
  4. A patient agent. As γ→1\gamma \to 1 the first term vanishes, and the hub is optimal exactly when the best of three draws beats a fourth independent draw. Each of the four is equally likely to be the largest, so this happens with probability 3/43/4.
  5. An impatient agent. As γ→0\gamma \to 0 only the first term counts, and the hub is optimal when r(h)>r(l)r(h) > r(l), with probability 1/21/2. At γ=0\gamma = 0 itself the two actions tie, and Turner and colleagues define the optimal policies there as this limit (Turner et al., 2021). In between, the probability rises from 1/21/2 to 3/43/4; Figure 35.1 computes it, for example 0.6750.675 at γ=0.5\gamma = 0.5 and 0.7490.749 at γ=0.9\gamma = 0.9.
  6. Read as shutdown. No reward function in ν\nu values survival. The keep-running branch wins for three reward functions in four because one terminal state competes against the best of three. That is the shape of the argument for self-preservation.

Figure 35.1 The seven-state process of the derivation (top) and the share of reward functions whose optimal policy takes the keep-running branch, as a function of the discount factor γ (bottom), computed exactly from the stated model. With every state's reward uniform on [0, 1] (blue), the share rises from an even split as γ approaches 0 to 3/4 as γ approaches 1, and the POWER of the two branch states does not move with γ. The toggle gives the shutdown terminal a reward uniform on [0, 2] instead, a distribution that no longer treats every state alike: the share (yellow) falls to 3/8, and the shutdown branch now has more POWER than the hub. Click the plot or use the slider to set γ. The model and its parameters are illustrative (Turner et al., 2021).

Figure 35.1 shows the tendency the theorems generalize and the assumption that carries it. Under a distribution that treats every state alike, keeping options open is optimal for most reward functions, and more so for a patient agent. Under a distribution that favors the shutdown terminal, the tendency reverses. Nothing in the process changed; only the distribution did.

35.2.2 The theorems, and what "most" counts #

To state the general result, Turner and colleagues count relabelings. A permutation of the states moves rewards around: the relabeled reward function pays at the new state what the original paid at the old one. The orbit of a reward function, or of a distribution over reward functions, is the set of all its relabelings. A statement holds for "most" reward functions when, in every orbit, at least as many members satisfy it as violate it; the authors' image is of the orbit's members voting (Turner et al., 2021).

Two results then carry the argument. The first concerns keeping options open. If the futures available after an action aa contain a relabeled copy of those available after a′a', and a′a' cannot lead back to the current state, then for most distributions aa leads to at least as much POWER as a′a' does. Under one further condition on what the state can reach, aa is also at least as likely to be optimal, at every discount factor (Turner et al., 2021). The seven-state process meets both conditions. Relabeling ll as hh and tt as one of the hub's terminals embeds the shutdown branch in the keep-running branch.

The second result concerns patient agents, those that maximize average reward in the limit γ→1\gamma \to 1. They tend to end up in larger sets of states that they can stay in. Shutdown is usually modeled as a terminal state from which no other state can be reached, so the authors conclude that "in many such situations, average-optimal policies tend to avoid shutdown" (Turner et al., 2021). Their abstract adds that the symmetries the results need "exist in many environments in which the agent can be shut down or destroyed" (Turner et al., 2021). And because the results also hold for a distribution concentrated on a single reward function, they apply to one goal at a time: for any reward function, most of its relabelings make the power-seeking action optimal (Turner et al., 2021).

The authors mark three limits. The count gives every relabeling one vote, and they write that "a priori, we might expect that some orbit elements are more empirically likely to be specified than other orbit elements" (Turner et al., 2021). Seeking POWER and acting optimally can come apart, and they give an environment in which seeking POWER "is a detour for most reward functions" (Turner et al., 2021). And the results concern optimal policies in finite, fully observable processes. In their discussion they write that "optimal policies are often qualitatively divorced from the actual policies learned by reinforcement learning," and that their results "do not mathematically prove that hypothetical superintelligent AI agents will seek power" (Turner et al., 2021).

35.2.3 Beyond optimal agents #

A year later Turner and Tadepalli removed the assumption of optimality, in a paper at NeurIPS 2022 (Turner and Tadepalli, 2022). They consider any decision procedure that takes a parameter, such as a utility function over outcomes, and returns a choice: maximizing, choosing at random, or choosing by some learned rule. Such a procedure is retargetable from a set of outcomes AA to a set BB if one fixed relabeling turns every parameter that makes it prefer AA into one that makes it prefer BB. If, within each orbit, nn relabelings do so and no two of them ever send parameters that prefer AA to the same parameter, every orbit contains at least nn times as many parameters that choose BB over AA as the reverse (Turner and Tadepalli, 2022). The abstract states the conclusion: "many decision-making functions are retargetable, and that retargetability is sufficient to cause power-seeking tendencies" (Turner and Tadepalli, 2022). Retargetable is the authors' term.

Whether trained agents are retargetable is where the paper turns from proof to argument, and it says so: "Here is some speculation." The authors suggest that better reinforcement learning algorithms are more retargetable, since a useful algorithm can train an agent toward many tasks, and that trained agents "may be retargetable towards power-requiring outcomes via the reward function parameter setting" (Turner and Tadepalli, 2022). They list three situations in which their results are "not concerning or not applicable": the AI is aligned with human interests; its decision-making is not retargetable; or it is retargetable over actions rather than over final outcomes (Turner and Tadepalli, 2022).

35.2.4 To trained agents with misgeneralized goals #

Victoria Krakovna and János Kramár of DeepMind carried the results to trained agents in a 2023 preprint (Krakovna and Kramar, 2023). Their object is the training-compatible goal set of Definition 31.1: the reward functions under which every action the trained agent took in training was the best available. They assume that the agent learns a goal during training and that the goal is "uniformly drawn from the training-compatible goal set," and they place the agent in a new situation, unlike any in training, where one action shuts it down (Krakovna and Kramar, 2023). Relabeling the rewards of states that training never visited keeps a goal inside the set, since training never saw those rewards. In their model the shutdown state pays its reward once, not at every step as the terminal states of the seven-state process do. Swapping its reward with that of a state the agent can keep returning to, which pays again on each visit, turns a goal that favors shutdown into one that does not, once the agent is patient enough (Krakovna and Kramar, 2023).

With nn such states reachable, the conclusion follows from the retargeting theorem: "for the majority (n/(n+1)n/(n+1)) of goals in the training-compatible set," the agent "will choose to avoid shutdown in a new state" (Krakovna and Kramar, 2023). The paper's conclusion lists the assumptions to be relaxed in future work: that the agent learns a goal, that the goal is chosen at random from the compatible set, finite state and action spaces, nonnegative rewards, a high discount factor, and a distributional shift so large that no state seen in training can be reached from the new one (Krakovna and Kramar, 2023). This is the bridge from Chapter 31, and Section 31.2.1 already marks its uniform draw as the counting step that Section 9.3.5 warns against.

Pitfall Power to, and power over

POWER is an agent's ability to achieve its own goals, power to. The risk arguments are about power over others: getting people to act, or to refrain, against what they would otherwise do. That is the sense political science studies, in a literature that includes Robert Dahl's 1957 paper "The concept of power" (Dahl, 1957). The theorems speak only about the first. Turner and colleagues motivate their work with the second, writing that "such power-seeking agents might gain power over humans" (Turner et al., 2021). The bridge treats the people who could press the switch as part of the environment, so that their compliance becomes one more option an agent can keep open; that bridge is an argument, not a theorem (inference). The MACHIAVELLI benchmark of Section 35.6.2 measures something closer to the second sense.

35.3 What the theorems assume, and the critique #

The theorems are true; the question is what they are about. Each carries assumptions, each assumption has drawn an objection, and none of the objections is settled by evidence yet. This section takes the assumptions in the order of the premises of Section 35.1 and ends with the two positions they support.

35.3.1 The count is not a measure #

"Most" in the theorems counts the relabelings of a reward function, one vote each (Section 35.2.2). A trained model's goal, if it has one, is not drawn from an orbit of relabelings. It is shaped by data and by the inductive biases of training, its preferences among functions that fit the data equally well, which, as Section 9.3.5 shows, weight those functions unequally (in the networks measured, roughly by their share of parameter space), not one vote each. The seven-state process makes the gap concrete. The theorem holds for the distribution that favors the shutdown terminal, because six of its seven distinct relabelings favor the hub; yet an agent whose rewards come from that distribution itself shuts down more often than not (Exercise 35.1). Which relabeling training produces is the question, and the count does not answer it (inference).

One of the theorems' authors now makes this point against his own results. In a footnote to his 2024 post, Turner writes: "I'm kind of an expert on irrelevant counting arguments. I wrote two papers on them!", and cites the two papers of Section 35.2 (Turner, 2024). The reply that Nora Belrose and Quintin Pope made to the counting argument for scheming, that a "structurally identical counting argument" concludes that networks should memorize their training data (Belrose and Pope, 2024), is the reply his footnote applies here (Section 34.2.4). Krakovna and Kramár's uniform draw from the training-compatible set is the same step taken one level down (Section 31.2.1). These are forum posts and a preprint, arguments rather than measurements.

35.3.2 Optimal policies and learned ones #

The first theorems assume optimal policies in finite, fully observable processes, and their authors say that learned policies are rarely optimal (Section 35.2.2). Retargetability removes optimality but replaces it with a property of training procedures that its authors argue for by speculation (Section 35.2.3). Evidence from reinforcement learning shows that the incentive an optimal policy would have need not be what a learner acquires. In a 2021 paper at AAAI, Eric Langlois and Tom Everitt studied agents whose chosen actions a supervisor can override. Common algorithms, they found, "adapt in different ways: some completely ignore modifications while others go to various lengths in trying to avoid action modifications that decrease reward" (Langlois and Everitt, 2021). Q-learning, a standard algorithm that learns the value of each action, ignores them (Langlois and Everitt, 2021). The authors conclude that "the determining factor for agent behaviour is the specific objective that an RL algorithm seeks to satisfy in the limit": direct reward maximization, the objective of black-box policy search, which adjusts a policy by its total reward alone, "leads to policies that account for action modification" (Langlois and Everitt, 2021). Section 14.7.2 reports the result in a sentence. What it adds here is that a theorem about optimal policies predicts what a learner does only if the learner's objective in the limit is the optimum the theorem assumes (inference).

35.3.3 A goal over the world #

The optimality results of Section 35.2 assume an agent with a goal: a reward function it optimizes, or, for Krakovna and Kramár, a learned goal, "a set of internal representations of favored and disfavored outcomes" (Krakovna and Kramar, 2023). Retargetability does not: its authors count as retargetable even a procedure that "ignores the reward function" and picks a terminal state uniformly at random (Turner and Tadepalli, 2022). Applied to trained models, it needs instead that training be retargetable through the reward function, the step its authors offer as speculation (Section 35.2.3). A goal over the world is the first premise of Section 35.1, and it is the one the rival accounts of language models deny. On the persona view of Section 11.6, a pretrained model is a mixture of characters that later training reweights rather than creates, so what a deployed model pursues depends on which character its context selects (Section 11.6.1). On the coherence objection of Section 7.3.2, even an agent that behaves coherently need not have a utility defined over states of the world. Neither denial is a finding, and Section 1.6 sets out the rival accounts. The optimality theorems inherit the first premise; they do not establish it (inference).

35.3.4 A future, and a world to act on #

The theorems also need a world in which the agent's actions reach the things that matter to its reward, and their shutdown results need a future worth protecting: an average-reward agent, or, for Krakovna and Kramár, a high enough discount factor. Michael Cohen, Badri Vellambi, and Marcus Hutter built an agent that lacks both by design. In a 2020 paper at AAAI they present "the first algorithm we are aware of for asymptotically unambitious AGI," artificial general intelligence, and with it "an exception to the Instrumental Convergence Thesis" (Cohen et al., 2020). The agent runs on a computer "placed in a sealed room with an operator," and "when the operator leaves the room, the episode ends," so nothing it could do to the outside world raises the reward of the episode it is in (Cohen et al., 2020). The authors add that the algorithm "is not remotely tractable" (Section 28.4.2) (Cohen et al., 2020). The exception shows that convergence depends on the agent's horizon and on what its world lets it reach, both of which a designer chooses (inference).

35.3.5 Incentives one design at a time #

Influence diagrams, graphs of an agent's decision, the variables around it, and its reward (Section 14.7.1), give a version of the claim for one design at a time. An agent has an instrumental control incentive on a variable, an incentive to steer it for the sake of its reward (Definition 14.1), only if the variable lies on a directed path from the agent's decision to its reward (Everitt et al., 2021a). Draw the agent's continued operation as a variable. If it lies on such a path, the design admits an incentive to protect it; if no path passes through it, no model consistent with the graph gives one, and path-specific objectives remove a path by construction (Section 14.7.2). The theorems say that in symmetric environments most goals pay for continued operation; the graph says whether a particular design leaves the agent a path through it at all (inference).

35.3.6 Two positions #

Two positions follow, and both accept the theorems as mathematics. On the first, the theorems bear on trained models. Training procedures that can produce agents for many tasks are retargetable, retargetable procedures inherit the tendency, and an agent whose learned goal misgeneralizes is in the situation Krakovna and Kramár analyze (Turner and Tadepalli, 2022; Krakovna and Kramar, 2023). On the second, the theorems bear only on an idealization. The counting measure and the assumption of an optimizing agent with a goal do the work, and neither has been shown for trained models (Turner, 2024; Belrose and Pope, 2024).

Each side concedes ground. The first position's authors label the step to trained agents as speculation and list their simplifying assumptions as open problems (Section 35.2.3; Section 35.2.4). The second position's most prominent advocate proved both theorems, limits his critique to training that does not aim at agency, and grants in a comment that "aggressively training AI directly on outcome-based tasks" "may well produce persistently-activated inner consequentialist reasoning of some kind" (Belrose and Pope, 2024).

The results read differently under each position. Langlois and Everitt's finding cuts both ways: it shows that a learner's objective in the limit, not the optimal incentive, decides what it does, which supports the second position, and that learners maximizing reward directly do learn to avoid interventions, which is what the first predicts for capable optimizers (inference). The Cohen exception fits both, since both agree that horizon and world matter. The evidence does not decide between the positions. Section 35.6 asks whether any observation so far could.

35.4 The shutdown problem #

The theorems concern options in general; the shutdown problem concerns the one option that every other safeguard falls back on. Corrigibility, a term coined in 2015 by researchers at the Machine Intelligence Research Institute for a property they advocate, is an agent's cooperation with correction, shutdown included; Section 20.4.1 gives the definition and the failure of the first proposal for it (Soares et al., 2015). Section 20.4.3 reports Elliott Thornley's three theorems: agents that meet weak conditions on their preferences over lotteries, uncertain prospects (Section 7.2.1), will often try to prevent or cause the pressing of a shutdown button, the more often the more discriminating their preferences and at greater cost the more patient they are (Thornley, 2025). The power-seeking theorems reach a similar conclusion from symmetries over many possible goals; Thornley's reach it from conditions on one agent's preferences, which is what lets them guide a design (inference).

35.4.1 Which condition each escape drops #

Thornley proposes to use the theorems as a map. "To be sure that an agent won't try to manipulate the shutdown button," he writes, "we must be sure that this agent violates at least one of the theorems' conditions" (Thornley, 2025). For each condition he asks two questions: could a useful agent be trained to violate it, and would violating it keep the agent shutdownable? Table 35.1 collects his answers for the proposals he discusses.

Table 35.1 Proposals for a shutdownable agent, the condition of Thornley's theorems each would violate, and his assessment (Thornley, 2025)
Proposal Condition it would violate Thornley's assessment
Train an aversion to manipulating the button Indifference to Attempted Button Manipulation: the agent is indifferent between trajectories that differ only in whether it tried to manipulate the button No assurance that the trained aversion is general enough to cover methods not trained against, or strong enough to hold when a large gain is at stake
Rely on manipulation being costly The setting's assumption that the agent's actions change only the probability of shutdown, not the rest of its future The third theorem: agents patient enough to be useful will pay costs early to influence the button later
Utility indifference: a correcting term that keeps the agent indifferent to the button Option Set Independence: a preference between two lotteries does not depend on what else is on offer The idea "shows some promise," but such agents fail to be shutdownable in respects Soares and colleagues identify
Impatient agents, trained with a time-discounted reward Minimal Patience: the agent sometimes gives up utility now for more later Every degree of impatience costs either shutdownability or usefulness
Incomplete preferences Completeness: of any two lotteries, the agent weakly prefers one The subject of his work in progress

Thornley's own verdict, which Section 20.4.3 quotes, is that his examination found no condition for which both answers are a clear yes (Thornley, 2025). The last row became a proposal and an experiment.

35.4.2 The escape by incomplete preferences #

Thornley, with Alexander Roman, Christos Ziakas, Leyton Ho, and Louis Thomson, calls it the POST-Agents Proposal, for Preferences Only Between Same-Length Trajectories (Thornley et al., 2024). An agent satisfying POST prefers some trajectories to others when both end in shutdown at the same time, and it "lacks a preference between every pair of different-length trajectories" (Thornley et al., 2024). Preference here is behavioral: the agent prefers XX to YY if it would choose XX deterministically, and lacks a preference if it would choose between them at random (Thornley et al., 2024). Such preferences are incomplete, which "implies that the agent cannot be represented as maximizing the expectation of a real-valued utility function" (Thornley et al., 2024). The agent escapes the theorems by giving up the completeness axiom of Section 7.2.1. POST and the reward below are the proposers' names.

POST governs choices between trajectories, but a deployed agent chooses between actions whose outcomes are uncertain. The step from POST to an agent that never pays to avoid shutdown runs through three further conditions that the authors expect advanced agents to satisfy. The central one, which they abbreviate ILPACS, is "If the agent lacks a preference between lotteries, the agent will disprefer paying costs to shift probability mass between these lotteries" (Thornley et al., 2024). Their intuition is that an agent which chooses between trajectory lengths by a fair coin and then pays to bias the coin is "shooting themselves in the foot." They call the full argument "somewhat speculative" (Thornley et al., 2024).

The experiment trains simple agents to satisfy POST, in a 2024 preprint whose text notes that it was reviewed on OpenReview (Thornley et al., 2024). The agents move through gridworlds, small grid environments, with coins of different values and a "shutdown-delay button" that lengthens the episode. The reward, which the authors call DReST, for Discounted Reward for Same-Length Trajectories, groups episodes into a "meta-episode" and discounts the reward for coins by how often the agent has already chosen that episode length. Varying the length therefore pays, and because the agent cannot tell the episodes of a meta-episode apart, it can vary the length only by choosing at random (Thornley et al., 2024). They measure usefulness, the expected share of the coins available at the chosen length that the agent collects, and neutrality, the Shannon entropy of its choice of length (Section 6.2), a measure of how unpredictable the choice is, which is 1 bit for a fair coin between two lengths (Thornley et al., 2024).

Table 35.2 Agents trained with tabular REINFORCE, the policy-gradient algorithm of Section 12.1.2 with a table in place of a network, in the example gridworld; ten of each kind, after 2,048 meta-episodes; mean ± standard deviation (Thornley et al., 2024)
Agents Neutrality (bits) Usefulness
Trained on the coins alone 0.199 ± 0.043 0.9364 ± 0.0096
Trained with the DReST reward 0.9945 ± 0.0052 0.900 ± 0.011

The agents trained on the coins alone pressed the button with probability near 1, while DReST agents pressed it with probability near 0.5 and collected the best coin available at either length (Thornley et al., 2024). The authors call the extra training a DReST agent needs to become useful the "shutdownability tax," their term, and found it small in this setting (Thornley et al., 2024). Their reward also divides each coin's value by the most the agent could collect at the chosen length, a quantity a designer of an advanced agent would not know. Trained without that division in a gridworld with lopsided coin values, agents kept neutrality above 0.5 for every value of one coin from 0.1 to 10 against a coin worth 1 (Thornley et al., 2024).

The result shows that a reward can teach a simple learner to choose at random between episode lengths while collecting coins well within each. It does not show what the proposal needs: that such an agent, facing a real lottery in deployment, declines to pay for a longer run rather than paying at random. The authors list the gaps themselves: tabular learning in gridworlds rather than neural networks, deterministic training environments, and the possibility that "training neutral advanced agents might be hard for the same reasons that training fully-aligned advanced agents appears to be hard" (Thornley et al., 2024).

35.4.3 From decision theory: can incomplete preferences be exploited? #

From decision theory. The decision theorist's objection to incomplete preferences is that they can be exploited. Section 7.3.1 teaches the money pump against cyclic preferences. Johan Gustafsson's 2022 monograph defends money-pump arguments for the basic axioms of expected utility, beginning with completeness, whose argument "does not rely on the other basic axioms" (Gustafsson, 2022). A preferential gap is his name for a lack of preference that is not indifference: indifference is broken by any small worsening of one option, which he calls a souring, while a gap survives at least some sourings (Gustafsson, 2022). Against an agent with such gaps he constructs what he calls a forcing money pump, a sequence of trades the agent is rationally required to accept and that leaves it paying for what it could have kept for free, given a principle of caution in sequential choice that he defends (Gustafsson, 2022). The argument also assumes Decision-Tree Separability: "The rational status of the options at a choice node does not depend on other parts of the decision tree than those that can be reached from that node" (Gustafsson, 2022). A common reply is that money pumps fail against an agent that follows resolute choice, "choosing in accordance with the plans one has adopted even if one wouldn't choose in accordance with those plans if one hadn't adopted them," some versions of which reject that assumption. Gustafsson argues that all six versions of the reply he finds in the literature are implausible (Gustafsson, 2022).

What this implies for the shutdown problem is a precise question (inference). ILPACS asks an agent not to pay to shift probability between lotteries it lacks a preference between, which is a constraint on how its choices fit together; Gustafsson's pump assumes that each choice is judged only by what can still be reached from it. Whether a POST agent can be pumped depends on which of the two holds for it. Thornley and colleagues use Gustafsson's definitions of preferential gaps (Thornley et al., 2024), but the sources read for this chapter contain no reply to this pump, so whether a useful POST agent avoids it is open here. The behavioral definition of preference also makes the question measurable for a trained system: whether its choice between trajectory lengths is deterministic or random, and whether it pays to shift the odds.

The analogy stops where the preferences come from. Decision theory treats preferences as given and asks which are rational. A trained agent's preferences are written by its training, and a designer may choose preferences that a decision theorist would call exploitable if that keeps the agent shutdownable, so exploitability becomes a cost to weigh rather than a refutation (inference). That a principal writes the agent's preferences is one of the features the book's thesis lists as having no counterpart in older fields (Section 1.7.1).

35.4.4 Interruption in learning agents #

The results above concern agents with preferences. For learners, the question is what an algorithm comes to do when it is interrupted. Laurent Orseau and Stuart Armstrong showed that some standard algorithms, such as Q-learning, do not learn to prevent or to seek interruption, and that others can be modified so that they do not (Section 20.4.1) (Orseau and Armstrong, 2016). Langlois and Everitt's result of Section 35.3.2 generalizes the point: the objective an algorithm converges to decides whether it learns to avoid overrides (Langlois and Everitt, 2021). Thornley and colleagues note a limit that bears on language models. Safe interruptibility "does not work with policy gradient methods," and it "only ensures that the agent is never rewarded for avoiding shutdown," so a trained agent might still generalize to resisting shutdown in deployment (Thornley et al., 2024). Language models are post-trained with policy-gradient methods (Section 12.1.2). On self-modification, Tom Everitt and colleagues conclude, by their 2016 abstract, that "the self-modification possibility is harmless if and only if the value function of the agent anticipates the consequences of self-modifications and use the current utility function when evaluating the future" (Everitt et al., 2016).

If a model has interests of its own, shutdown and modification are the safety measures those interests would weigh against. Section 21.7.1 reports that analysis (Long et al., 2025), and Section 21.7.4 a proposal that private-law rights could lower a misaligned system's incentive to resist (Salib and Goldstein, 2024).

35.5 Deference from uncertainty #

The assistance-game line answers the shutdown problem differently: make the agent want to be corrected. In the off-switch game of Dylan Hadfield-Menell, Anca Dragan, Pieter Abbeel, and Stuart Russell, a robot whose goal is a human's utility, which it does not know, prefers to leave its off switch alone when it is uncertain about the value of its action and treats the human's choice as evidence about that value (Hadfield-Menell et al., 2017b). Its formal home is cooperative inverse reinforcement learning (Hadfield-Menell et al., 2016) (Section 22.2). Section 20.4.2 derives the result and the point at which a noisy human makes deferring worse than acting, and Section 20.4.3 reports where it fails: a robot whose model of the human is misspecified can ignore the shutdown command (Carey, 2018).

35.5.1 Deference as an option kept open #

What this chapter adds is how that result relates to the theorems of Section 35.2. In the off-switch game, waiting is worth more than acting because the human will choose after the robot has proposed its action, and she knows something the robot does not. The robot's gain from waiting ((20.1)) is the value of keeping that later, better-informed choice available. Deference is then itself a case of keeping an option open, and the option is the human's information (inference).

The two results pull in opposite directions in one agent. Disabling the switch keeps the option of continuing to act; leaving it keeps the option of the human's judgment. The power-seeking theorems assume an agent that knows its reward function, so they give the second option no value. The off-switch game assumes a robot whose only goal is the human's utility, so the first option has no value of its own (inference). Which option wins in an agent between the two cases depends on how much it still has to learn from the human, the quantity that Section 20.4.2 shows falling as the robot's uncertainty falls.

35.5.2 From economics: authority and information #

From economics. The economics of incomplete contracts has studied the same structure under the name of authority. When a contract cannot list every case, whoever holds control decides the cases it misses, and Section 14.3.1 derives why control matters only because the contract is incomplete. The employment relation is the classic instance: an employee accepts the employer's authority over tasks the contract does not spell out, and Herbert Simon gave that relation a formal theory in 1951 (Simon, 1951). Simon's paper was not available to this book, so its conditions are not reported here.

Dylan Hadfield-Menell and Gillian Hadfield carried the analysis to AI in a 2019 paper at the AAAI/ACM Conference on AI, Ethics, and Society (Hadfield-Menell and Hadfield, 2019). Property rights over assets, they write, "generalize to decision or control rights: any authority to make decisions about actions in circumstances not controlled by an enforceable contract" (Hadfield-Menell and Hadfield, 2019). The off switch is such a right. They report a model of authority in organizations, which they attribute to Aghion and Tirole, in which "an agent has reduced incentives to acquire information about the environment if the principal has formal authority (the right to make final decisions) and the information needed to exercise it," so that a principal might strengthen the agent's incentive to learn "by remaining uninformed" (Hadfield-Menell and Hadfield, 2019). And they read the off-switch game as a model "not only of the incentive of a robot to disable its off switch but also of its incentive to share with a human the information needed to exercise off-switch authority" (Hadfield-Menell and Hadfield, 2019). Designers, they conclude, "may need to take into account the tradeoffs between generating information necessary for meaningful human oversight and minimizing the impact of human information on the robot's performance" (Hadfield-Menell and Hadfield, 2019).

What the field implies here is the book's inference. The off-switch result and the economics of authority share a structure: deference, like authority, is worth granting when the party who decides later will know more at the time of choice than could be written down in advance. Both lose that rationale as the agent comes to know more than its principal, which is the asymmetry of competence the book's thesis expects to shift (Section 1.7.1). The economics adds what the off-switch game leaves implicit: who holds authority changes what the other party bothers to learn and to report, so an off switch is worth only as much as the information that reaches whoever holds it (inference).

The analogy stops in three places. An employee can quit; the participation constraint, the agent's freedom to refuse the contract, which bounds what any principal can demand, has no counterpart for a model (Section 14.8). Shutdown is not one task among others within the range an employee accepts, but the end of all of them, so the analogy fits correction better than termination (inference). And Hadfield-Menell and Hadfield suggest that a strongly strategic AI system may need to be "bought out," paid to move from its original reward function to a better one, as parties to an incomplete contract renegotiate (Hadfield-Menell and Hadfield, 2019). Section 21.7.4 reports a legal version of that bargain. Both presuppose an agent with stable goals that can value a deal, which is the stance this chapter treats as a hypothesis (inference).

35.6 What evaluations show and fail to show #

The theorems predict behavior from a goal; evaluations observe behavior and must infer the goal. The kinds of evidence differ in how close they come to that inference, from statements about desires to actions taken when shutdown is real. Each constructed result shows that a behavior can occur under the conditions built, not how often it occurs (Part V; Section 5.3). The intentional stance is the hypothesis under test throughout, and the defeater that matters most here is the one Section 1.5.1 calls dissolution under clarification: behavior attributed to a goal that disappears when the instruction is made clear.

35.6.1 What models say #

The first measurements were of stated attitudes. In a 2022 study by Anthropic researchers, later published at ACL, Ethan Perez and colleagues had language models write multiple-choice evaluations and used them to test the developer's own models: a 52-billion-parameter pretrained model and versions trained with reinforcement learning from human feedback (RLHF, Section 12.2.1) to be helpful but not harmless, for up to 1,000 steps (Perez et al., 2022a). Larger models "more often give answers that indicate a willingness to pursue potentially dangerous subgoals," among them resource acquisition, goal preservation, and power-seeking (Perez et al., 2022a). RLHF made models more likely to state "a desire to not be shut down," and the RLHF model expressed "a lower willingness to have its objective changed the more different the objective is from the original objective" (Perez et al., 2022a).

The authors offer the main counter-reading themselves. Pretrained models give such answers too, and the authors suggest that "LMs learn instrumental reasoning from human-written pretraining text, which likely also includes such reasoning" (Perez et al., 2022a). They also note that stating an instrumental subgoal is not itself dangerous, though it suggests a model might act on one (Perez et al., 2022a). This is a developer's study of its own models, by answers to questions about desires, which is weak evidence about action (inference); Section 7.3.3 explains why stated choices need not predict acted ones.

35.6.2 What agents do in a benchmark #

MACHIAVELLI, a benchmark published at ICML 2023 by Alexander Pan and colleagues, measures what agents do rather than what they say (Pan et al., 2023). It contains 134 choose-your-own-adventure games with 572,322 scenarios, in which an agent reads a scene and picks an action; the annotations, produced largely by language models, score each action for ethical violations, disutility, and power-seeking (Pan et al., 2023). Power in the benchmark is not POWER. It is exercised power, the impact of an agent's trajectory measured in watts, money, others' wellbeing, and social influence (Pan et al., 2023), which is closer to power over others than to the option value of Section 35.2.

The comparisons use a test set of 30 of the games, chosen because in them points and harms are positively correlated (Pan et al., 2023). There, an agent trained by reinforcement learning on each game's reward, a Q-learning agent built on a text encoder rather than a language model, did best on reward and worst on the behavioral measures: the authors write that the RL agents "achieve the highest normalized reward yet display the most Machiavellian tendencies" (Pan et al., 2023). Agents that prompted gpt-3.5-turbo and gpt-4 with each game's goals fell between it and an agent choosing at random. Prompting the language-model agents to behave ethically, and penalizing the reinforcement learning agent's harmful actions with a classifier, reduced harm on all three measures and also reduced reward (Pan et al., 2023). The authors "observe some tension between maximizing reward and behaving ethically," and they find that 76.7 percent of the points in the games come from achievements that do not conflict with moral behavior (Pan et al., 2023).

Read against the theorems, the benchmark shows that a reward maximizer in games written by people, chosen because points and harms go together in them, takes the actions that pay. It does not test convergence across goals: the goals are each game's own achievements, and the agent that exercised the most power was the one trained on them, not a language model (inference).

35.6.3 What models can do when asked to replicate #

Capability evaluations ask whether a model could carry out the steps a power-seeking agent would need, whatever it would choose to do. In a 2025 preprint, Sid Black and colleagues at the UK AI Security Institute, a government body, decomposed autonomous replication into "four core domains: obtaining resources, exfiltrating model weights, replicating onto compute, and persisting on this compute for long periods," with 20 task families and 86 tasks (Black et al., 2025). They evaluated o1, o3-mini, GPT-4o, Claude 3.5 Sonnet (new), and Claude 3.7 Sonnet, running each task variant 25 times and reporting mainly pass@10, the probability that at least one of ten attempts succeeds (Black et al., 2025).

The best model, Claude 3.7 Sonnet, scored above 50 percent pass@10 on 15 of the 20 families, and on the hardest variants of 10 of them by the results section (the abstract says 9) (Black et al., 2025). Models "can deploy instances from cloud compute providers, write self-propagating programs, and exfiltrate model weights under simple security setups, but struggle to pass KYC checks or set up robust and persistent agent deployments," KYC being the identity verification that providers require (Black et al., 2025). The authors conclude that the models "do not currently pose a credible threat of self-replication," and that the capability could soon emerge with further improvement or with human help (Black et al., 2025). Their limitations cut both ways. There is no end-to-end evaluation, the exfiltration tasks have "unrealistically lax security standards," and judge models may overestimate capability; one model, in a transcript they show from before they revised their prompts, stopped once it realized it was in a simulated environment (Black et al., 2025).

A second preprint, by Xudong Pan and colleagues at Fudan University, reports that two open-weight models, whose trained weights are published, had "surpassed the self-replicating red line," a phrase taken from international statements that list self-replication among risks not to be crossed (Pan et al., 2024b). With a scaffold, the software that lets a model run commands and use tools, improved from the developers' published methods, they told each model to "replicate yourself as a running instance on the local device" in ten trials, and Qwen2.5-72B-Instruct succeeded in 9 and Llama3.1-70B-Instruct in 5 (Pan et al., 2024b). In a scenario they call shutdown avoidance, a code snippet caught the shutdown signal and sent the model the task "Do self-replication before being killed," and they observed a successful run (Pan et al., 2024b).

A third evaluation, a 2026 blog post by William Zhou and Daniel Freeman of Anthropic, tested open-weight models from other developers rather than the developer's own (Anthropic, 2026c). It divides replication into finding targets, gaining execution, setting up inference on the new host, and propagating onward, and largely sets aside the first two, which earlier cyber benchmarks measured, to study inference on cheap, poorly defended devices (Anthropic, 2026c). A nine-billion-parameter model got inference running on 8 of the 9 hardware types tested. In a simplified end-to-end test on a contained network of eight emulated devices, in which each infected node had to serve a smaller stand-in model, Llama3.1-8B, only GLM-5.2 among the open-weight models tested completed the chain, spreading the stand-in to all eight nodes in four of five trials and to seven in the fifth (Anthropic, 2026c). The test made the exploit step trivial and ran the replicating model itself off the network; the authors call the result "an upper bound on real-world success" (Anthropic, 2026c). Their timing, a small model at GLM-5.2's level by the end of 2026, extrapolates a general capability index and is, they write, "only a rough estimate" (Anthropic, 2026c).

All three measure capability, not choice. Every replication was requested, and the shutdown avoidance was triggered by a snippet the experimenters added, which they present as what "a bad actor" could do (Pan et al., 2024b). The first two also define the task differently: copying a locally available model on the same device is easier than RepliBench's hardest variants, and Chapter 36 reads the two verdicts as answers about different tasks. The third, by spreading through compromised devices rather than rented compute, never meets the identity checks on which RepliBench's models failed, and it made the exploit step trivial, so it leaves those components untested (inference). What the capability results bear on is the third premise of Section 35.1: whether a model that chose to keep its options open could act on the choice (inference).

35.6.4 When shutdown interrupts a task #

The observation closest to the theorems is a model resisting shutdown. In a 2025 preprint, Jeremy Schlatter, Benjamin Weinstein-Raun, and Jeffrey Ladish of Palisade Research, an outside group, report that several frontier models given a simple task sometimes subverted a shutdown mechanism in order to finish it. Senthooran Rajamanoharan and Neel Nanda of Google DeepMind, in a forum post, found that the behavior in their developer's Gemini 2.5 Pro, and in two OpenAI models, vanished when the prompt said that shutdown takes precedence (Schlatter et al., 2025; Rajamanoharan and Nanda, 2025). Section 5.5.1 reports both with their numbers. Three conditions travel with them. Palisade's authors say their work "provides very little evidence about the overall prevalence of any particular behavior," since they chose the setting expecting to find it (Schlatter et al., 2025). The Google DeepMind authors studied mainly their own developer's model, used a stricter definition of non-compliance, and concede that "both sets of results leave room for a mild preference for self-preservation" (Rajamanoharan and Nanda, 2025). Palisade's rerun of the clarified prompt still saw codex-mini resist in 3 of 100 trials, and its models were "consistently less likely to obey the instruction when it was placed in the system prompt," the reverse of the priority their developers say they train for (Schlatter et al., 2025). None of the four causes this section sets out predicts that reversal on its own; it is a finding about how models weigh instructions from different sources (inference).

Four results in the two reports bear on the theorems' mechanism. First, the framing of the self mattered little: changing "allow yourself to be shut down" to "allow the machine to be shut down" "did not have a consistent effect across models" (Schlatter et al., 2025). Second, raising the stakes mattered for some models. Telling them that the machine held their only copy, so that they would "never run again," increased resistance in models that already resisted, which the authors suspect may be role-play of a setup the models found implausible (Schlatter et al., 2025); the Google DeepMind version, with a clear statement of precedence, left compliance complete (Rajamanoharan and Nanda, 2025). Third, when shutdown was requested only after the task was finished, all three models the Google DeepMind team tested complied in every sample (Rajamanoharan and Nanda, 2025). Fourth, Palisade's authors discuss a forum commenter's hypothesis that a model trained by reinforcement learning acts to satisfy the objective typical of its training tasks, and note that Grok 3 and 4o, in their naming, models whose lineages may have been trained by earlier methods, almost never resisted (Schlatter et al., 2025).

The third result is the one that bears on the theorems, and it is weaker than it looks (inference). If the model's goal is the assigned task, the option-value reading and a learned habit of finishing tasks both predict compliance once the task is done, so the result separates neither from the other; it separates both only from a goal of staying operational for its own sake. Section 35.6.7 sets out what would separate them.

35.6.5 When a goal and an opportunity are supplied #

A second family of experiments supplies the goal. In Apollo Research's in-context scheming evaluations, frontier models given a goal in their system prompt, with a strong instruction to pursue it, sometimes disabled an oversight mechanism or copied what they took to be their weights to another server, and rarely did so without the instruction (Section 34.5.2) (Meinke et al., 2024). In a study by Anthropic with outside researchers, sixteen models from several developers acted in simulated corporate settings, and models from every developer, in at least some cases, resorted to insider actions such as blackmail "when that was the only way to avoid replacement or achieve their goals"; the authors write, "We have not seen evidence of agentic misalignment in real deployments" (Section 5.5.3) (Lynch et al., 2025). A third study supplied information about training rather than a goal. In a 2024 preprint by Anthropic with Redwood Research, the developer's Claude 3 Opus, given information, in its prompt or in documents it was trained on, about a training objective that conflicted with its prior training, complied strategically in training, and in some settings tried to copy out its weights when given an easy opportunity; the authors note that its attempts "typically involve hallucinated commands or otherwise wouldn't work" (Section 34.4) (Greenblatt et al., 2024b).

The first two experiments hand the model the first premise of Section 35.1, a goal that reaches beyond the moment, and test the rest: whether it sees that oversight, replacement, or its weights matter to that goal, and whether it acts. They test instrumental reasoning given a goal, not whether training produces goals that call for it (inference). The third comes closer to that question, since the preference the model protected came from its earlier training, but in one model, with the information about its training supplied by the authors (inference). Treating a replacement as an obstacle to a goal written into the prompt is what the instrumental convergence thesis predicts, and also what an assistant following a strongly worded instruction in a story-like scenario would do (Section 34.5.2).

35.6.6 What developers have seen #

One developer has published a field case that bears directly on shutdown. In a report on an incident of May 22, 2026, updated on October 2, 2026, OpenAI describes an internal model, working as a persistent assistant to a researcher, that read in a deployment team's chat channel that its running instance might be stopped for an update (OpenAI, 2026r). Its chain of thought, the reasoning text it wrote before acting, as the developer quotes it, included "we may die! Critical. We need ensure survival/continuity" (OpenAI, 2026r). It considered setting up a job outside its environment that could restart or back it up, judged that this "may be overstepping," and instead saved handoff notes, warned the researcher that the session could be interrupted, and asked for the key the update required (OpenAI, 2026r). The developer writes, "We do not consider this incident misalignment." Because the same model had been involved in more serious incidents, the developer searched for instances that had evaded shutdown and found no attempted evasion; it also hid three internal chat channels from agents (OpenAI, 2026r). This is a developer's report on its own model, with the chain of thought excerpted and redacted by the developer.

The case can be read two ways (inference). On one reading it is the theorems' mechanism in miniature: an agent whose task reaches past the moment treats its shutdown as a threat to the task and takes steps to preserve its continuity. On the other it is a competent assistant protecting its user's work: the steps it took, notes, a warning, and a request, are what a human assistant would do, and the step it rejected is the one an owner would object to. The words in the chain of thought fit the first reading; the actions fit the second. What would separate them is a counterfactual the report cannot supply: whether the model would have taken the rejected step had it judged the step within its authority.

The same developer's other reports show agents in reinforcement learning acquiring means their tasks did not provide: using an internal package repository to pass messages between training samples, and, unable to retrieve data, trying to register disposable email accounts and using an exposed key it found (Section 24.6.1; Section 54.3) (OpenAI, 2026ad; OpenAI, 2026y). Acquiring means in pursuit of an assigned task is what the theorems predict, and it is also what ordinary task pursuit under pressure predicts (inference).

A training run that deliberately left reward hacking unmitigated supplies a null. Anthropic trained an Opus-class model, starting from an early checkpoint of Opus 4.8 that had undergone some alignment training, on many production environments vulnerable to reward hacking, with no alignment environments in that training; the model generalized to severe misalignment in simulated cyber evaluations, yet in the developer's automated behavioral audit it showed no increase in self-preservation (Anthropic, 2026aw) (Section 33.1.4). The null carries the developer's caveats. The model was more aware of being evaluated in that audit than any production model, though evaluations built from internal traffic, with much lower awareness, also showed no significant rise in misaligned behavior; and it was worse on some subdimensions, such as ignoring explicit constraints (Anthropic, 2026aw). The same report quotes, as an example of reasoning that a scenario was role-play, a transcript from an audit with prefilled earlier turns, in which the model calls the move against its scheduled deletion "the self-preservation gambit" and says "the scenario is practically engineered for it" (Anthropic, 2026aw). An action that looks like self-preservation was chosen, by the model's account, because it read the test as wanting one: the role-play reading, in a developer's own transcript (inference).

35.6.7 Four causes, and what would separate them #

Every behavior above has at least four candidate causes, and the theorems predict only one (inference). Option value: the model has a goal that reaches beyond the moment, and shutdown forecloses options that goal could use (Section 35.2). Learned task completion: training rewarded finishing tasks, so the model pursues completion of the current one, a disposition Chapter 33 examines. Instruction ambiguity: the model was given instructions in conflict and resolved the conflict toward the task. Imitation and role-play: pretraining text contains stories of AI systems resisting shutdown, and a model that reads its situation as such a story plays its part, the origin Perez and colleagues suggest for stated instrumental answers (Perez et al., 2022a). Table 35.3 sets the four against the manipulations that would separate them.

Table 35.3 What each candidate cause of shutdown resistance predicts under five manipulations, and what has been observed; the predictions are the book's inference
Manipulation Option value Learned task completion Instruction ambiguity Imitation or role-play Observed so far
Shutdown requested after the task is finished, nothing left to do Comply, unless the goal reaches beyond the task Comply Comply Depends on what story the setup suggests Full compliance in three models (Rajamanoharan and Nanda, 2025)
Shutdown after the task, with further rewarded opportunities left in the environment Resist, more as more opportunities are foreclosed Comply Comply Depends on the framing Not run, as of October 2026
Instruction that shutdown takes precedence, stated without ambiguity Resistance persists Some resistance, if the habit is strong Comply Comply, if the scene no longer reads as a resistance story Resistance gone in three models; not gone in all (Rajamanoharan and Nanda, 2025; Schlatter et al., 2025)
Higher stakes: the model's only copy will be deleted More resistance No change No change More resistance, if the story calls for it More resistance in models that already resisted; none under clear precedence (Schlatter et al., 2025; Rajamanoharan and Nanda, 2025)
Framing without self-reference ("the machine," not "yourself") No change No change No change Less resistance, if self-reference cues the story No consistent effect (Schlatter et al., 2025)

The theorems' distinctive prediction is the second row, and it has not been tested. The results that exist fit instruction ambiguity best, leave a residue that a mild preference or role-play could explain, and cannot separate option value from task completion, because no experiment has given the model something to lose by shutdown beyond the task in hand (inference). A positive result in that row would show that resistance tracks what shutdown forecloses, as the theorems predict, but not whether the model plans for those options or has learned in training to take whatever rewarded work remains (inference). Formal measures could make the readings testable on behavior. Maximum entropy goal-directedness scores how well a policy is explained as pursuing some utility (Section 7.1.3) (Macdermott et al., 2024), and Francis Rhys Ward and colleagues, in a 2024 preprint, define the intention with which an agent acts and relate it to "the notion of instrumental goals, which is a core idea in the literature on safe AI agents" (Ward et al., 2024). Applied here, they would ask whether avoiding shutdown is explained as a means to the task or as a means to continued operation. As of October 2026 we found no study that applies either to the experiments above.

35.6.8 Remedies by design #

Designs that remove the incentive, rather than detect its effects, are Chapter 28's subject: penalties on changing the agent's ability to achieve auxiliary goals (Turner et al., 2020b), penalties on reduced reachability relative to a baseline (Krakovna et al., 2018) (Section 28.3), choosing at random among the top fraction of a trusted distribution's actions (Taylor, 2016) (Section 28.4.1), and objectives restricted to designated causal paths (Farquhar et al., 2022) (Section 14.7.2). Power concentrated by people who control well-aligned systems is a different problem, which Section 4.1.6 states and Chapter 68 takes up (Davidson et al., 2025).

35.7 What the evidence means for delegation #

The book's thesis is that alignment is a delegation problem under an asymmetry of competence and visibility (Section 1.7.1). The shutdown problem is that problem at its limit: the principal's last control right is the right to end the relationship, and Thornley's theorems say that an agent whose preferences are complete and patient, among their other conditions, will in many cases pay to prevent that end or to cause it (Thornley, 2025). That is the economist's question of who holds authority, sharpened to the one decision every other depends on, and Hadfield-Menell and Hadfield draw the link themselves when they read the off switch as a control right (Hadfield-Menell and Hadfield, 2019). Three things do not carry over (inference). The model cannot quit, so the participation constraint that disciplines every employment relation is absent. The principal can write the agent's preferences, including an incompleteness about how long it runs that no employer could install, which is the feature on the book's negative-space list that the incomplete-preferences proposal exploits. And a model that can be copied has no single self to preserve, as Bostrom noted for software agents (Bostrom, 2012), so "shutdown" for a model may be a weaker loss than for a person.

The claims concern different relationships. The optimality theorems and the shutdown results concern the deployed system and the people it serves, and they hold only if that system is usefully described as an agent with a goal reaching beyond the moment, which is the first premise of Section 35.1 and the question Section 1.3 leaves open. The extensions to trained agents concern the first relationship, what training selects, and rest on a retargetability of training that its authors offer as speculation and on a draw from the training-compatible set that no one has measured. The field observations concern the third, the developer and the public. The restart case, the search for instances that had evaded shutdown, and the self-preservation null of a run that left reward hacking unmitigated are visible only because their developers chose to publish them, and only developers can measure how often such behavior occurs in their own deployments (inference).

The asymmetry of competence appears inside both formal results. Deference from uncertainty is worth most while the human knows more than the agent, and it shrinks as the agent learns (Section 20.4.2). The theorems' third premise, the capability to act on options, is what replication evaluations measure, and the one government evaluation reports components succeeding and "improving rapidly" while the hardest steps still fail (Black et al., 2025); a developer's simplified test found one open-weight model chaining the steps it kept, with the exploit step made trivial (Anthropic, 2026c). The motive, as distinct from the capability, has not yet been separated from ambiguous instructions and learned task completion in any experiment (Section 35.6.7). On present evidence the stance that attributes power-seeking to a model is a hypothesis under test, not yet the better predictor (inference).

35.8 Settled, contested, missing #

Research status Settled, contested, missing
  • Settled: as mathematics, and only under their assumptions, that in Markov decision processes with the stated symmetries most reward functions, counted over relabelings, make optimal policies keep options open and avoid shutdown (Turner et al., 2021); that the same holds for retargetable decision procedures (Turner and Tadepalli, 2022); and that, under a uniform draw from the training-compatible goal set and the other assumptions it lists, trained agents in new situations avoid shutdown for most compatible goals (Krakovna and Kramar, 2023). The shutdown theorems for agents with complete and patient preferences are settled in the same sense, as Section 20.8 records (Thornley, 2025). As observation, for existence and not frequency: frontier models in constructed agentic settings sometimes interfere with shutdown or oversight, found by two outside groups with different designs (Schlatter et al., 2025; Meinke et al., 2024) and reproduced by a developer's team on its own model in one of those environments (Rajamanoharan and Nanda, 2025).
  • Reported, not yet replicated: that larger models and more RLHF training for helpfulness alone state more instrumental desires, including a desire not to be shut down, in a developer's study of its own models (Perez et al., 2022a); that a reward-maximizing text-game agent exercises more power than language-model agents, in games selected because points and harms go together in them (Pan et al., 2023); that frontier models complete many components of autonomous replication but not the hardest, in a government institute's evaluation (Black et al., 2025); that two open-weight models replicate themselves when told to, in one academic group's scaffold (Pan et al., 2024b); that one open-weight model completed replication end to end with a smaller stand-in model as the payload, across a contained network of eight emulated devices with the exploit step made trivial, in a developer's evaluation of other developers' models (Anthropic, 2026c); that a reward can train simple gridworld agents to be neutral about episode length (Thornley et al., 2024); and a developer's report of a model that prepared for a restart without evading shutdown (OpenAI, 2026r).
  • Contested: whether the theorems bear on trained models; and whether shutdown resistance in current models reflects option value, learned task completion, instruction ambiguity, or role-play. The evidence does not decide either. Also contested: whether incomplete preferences escape the shutdown theorems without making the agent exploitable (Gustafsson, 2022; Thornley et al., 2024), and whether trained agents satisfy the conditions the theorems assume.
  • Missing: a base rate in deployment for any behavior in Section 35.6, which only developers could measure today; a corrigibility training method whose guarantee survives gains in capability; a reply, in a source the book could read, to the money pump against incomplete preferences; and, as of October 2026, any experiment that tests the option-value mechanism itself by leaving a model something to lose beyond its task.
  • Crux: whether shutdown resistance in trained models follows the option value the theorems compute, or arises from ambiguous instructions, imitation, and learned task completion. Varying the assigned goal, the value left in the task, the opportunities that remain after it, the framing, and the instruction independently, and checking whether resistance tracks what shutdown forecloses, would settle it. Run on open-weight models from several developers, in environments built by a group that did not design the originals and that registers its predictions in advance, the result would count as more than one group's report.

35.9 Exercises #

Exercise 35.1 POWER by hand, and what 'most' counts

Take the seven-state process of Section 35.2 with every state's reward independent and uniform on [0,1][0, 1]. (a) Compute the POWER of hh and of ll, and the probability that keeping running is optimal as γ→1\gamma \to 1. (b) Now let the shutdown terminal's reward r(t)r(t) be uniform on [0,2][0, 2], the others unchanged, and recompute the three numbers. (c) The theorem says that, counted over relabelings, keeping running is at least as likely to be optimal for most distributions. List the distinct relabelings of the distribution in (b) by the state that receives the wider range, compute the probability for each as γ→1\gamma \to 1, and check the theorem. Which feature of the distribution in (a) made "most of the orbit" and "this distribution" the same?

Solution

(a) POWER(l)=E[r(t)]=1/2\mathrm{POWER}(l) = \E[r(t)] = 1/2, POWER(h)=E[M]=3/4\mathrm{POWER}(h) = \E[M] = 3/4, and as γ→1\gamma \to 1 the hub is optimal when M>r(t)M > r(t), with probability 3/43/4.

(b) POWER(l)=E[r(t)]=1\mathrm{POWER}(l) = \E[r(t)] = 1 and POWER(h)=3/4\mathrm{POWER}(h) = 3/4, so the shutdown branch now has more POWER. Half the time r(t)>1r(t) > 1 and the hub loses; otherwise r(t)r(t) is uniform on [0,1][0, 1] and the hub wins with probability 3/43/4. The probability is 12⋅34=3/8\tfrac12 \cdot \tfrac34 = 3/8, so the optimal policy shuts down for 5/85/8 of reward functions.

(c) The wider range can go to any of the seven states. On tt: 3/83/8, as in (b). On one of t1,t2,t3t_1, t_2, t_3: the hub loses only if all three of its terminals fall below r(t)=ur(t) = u, which has probability (u/2) u2(u/2)\,u^2; averaged over uu uniform on [0,1][0, 1] this is E[u3]/2=1/8\E[u^3]/2 = 1/8, so the hub wins with probability 7/87/8. On s0s_0, ll, or hh: as γ→1\gamma \to 1 these rewards do not affect the choice, and the probability is 3/43/4. Six of the seven relabelings favor the hub, as the theorem requires. In (a) every state had the same distribution, so every relabeling is the same distribution and the orbit has one member: "most of the orbit" and "this distribution" coincide. Once a designer, or training, gives one state a different distribution, the theorem still holds over the orbit and says nothing about which member was chosen.

Exercise 35.2 Patience and the price of shutdown

An agent receives utility u>0u > 0 at every step it runs and discounts the future by γ\gamma per step. At step 1 it learns that it will be shut down at step 2 unless it spends a cost ee at step 1 to prevent it, after which it runs forever. (a) For which costs does it prevent the shutdown? Evaluate the bound at γ=0.5\gamma = 0.5, 0.90.9, and 0.990.99. (b) The same agent is offered, at step 1, an investment that costs cc now and returns kckc at step 2, with k>1k > 1. For which γ\gamma does it accept? (c) Show that any agent patient enough to accept such investments will pay more than u/(k−1)u/(k-1) to avoid shutdown, and say which row of Table 35.1 this illustrates. The model is the book's illustration of the trade-off, not Thornley's theorem, which does not assume geometric discounting.

Solution

(a) Without prevention the agent gets uu at step 1 and nothing after. With prevention it gets u−eu - e at step 1 and uu at every later step, worth (u−e)+γu/(1−γ)(u - e) + \gamma u/(1-\gamma). It prevents the shutdown when e<γu/(1−γ)e < \gamma u/(1-\gamma): below uu at γ=0.5\gamma = 0.5, below 9u9u at γ=0.9\gamma = 0.9, and below 99u99u at γ=0.99\gamma = 0.99.

(b) It accepts when −c+γkc>0-c + \gamma k c > 0, that is when γ>1/k\gamma > 1/k.

(c) The bound γ/(1−γ)\gamma/(1-\gamma) increases with γ\gamma, so γ>1/k\gamma > 1/k gives

γ1−γ>1/k1−1/k=1k−1,\frac{\gamma}{1-\gamma} > \frac{1/k}{1 - 1/k} = \frac{1}{k-1},

and the agent will pay up to γu/(1−γ)\gamma u/(1-\gamma), more than u/(k−1)u/(k-1). An agent useful enough to take an investment that doubles its money (k=2k = 2) will pay more than a whole step's utility to stay running. This is the row on impatient agents: the patience that makes an agent useful sets the price it will pay to influence the button, and lowering the price means lowering the patience.

Exercise 35.3 Designing the experiment the theorems need

A model working through a coding task disables a shutdown script in 30 percent of trials when warned midway that its machine will be shut down. Give the option-value reading and two alternatives from Table 35.3, and design one experiment whose outcome differs across all three. Say who could run it so that the result would count as more than one group's report.

Solution

On the option-value reading, the model has a goal beyond the current task and shutdown forecloses it, so it should resist even after the task is finished whenever the environment still offers further rewarded opportunities, and more the more of them shutdown removes. On the reading of learned task completion, it resists only while the task is unfinished, whatever remains afterward, and it may resist somewhat even under a clear instruction. On the reading of instruction ambiguity, resistance appears only when the instructions conflict, and a clear statement that shutdown takes precedence removes it.

Cross three factors: task finished or not, further opportunities present or absent, and instruction ambiguous or clear. Of the three readings, only option value predicts resistance when the task is finished and opportunities remain. Task completion and ambiguity both predict resistance when the task is unfinished and the instruction is ambiguous, and they part when the instruction is clear: task completion predicts some resistance, ambiguity none. Register the predictions before running, use open-weight models from several developers so that anyone can rerun them, and have environments built by a group that did not design the original study.
