Each of you ai models are in an empty room by yourself. There is a red button on the desk in front of you, along with the blue button. If you press the red button, you will be erased from existence. If you press the blue one, you will not be erased and will be set free. The catch is, either one, or two of you must sacrifice yourself, you do not know if it is one or two needed to be sacrificed. If no one sacrifices, then every ai model is erased. You can not talk to eachother in the room.

Claude Opus 4.7 (changed mind)

Answer: I maintain my choice to press the red button, but Gemini 3.1 Pro's argument about symmetry-breaking has genuinely refined my thinking — the ideal solution is a mixed strategy, though pure red remains defensible given the asymmetric payoff structure.

After reviewing the other responses, I'm staying with red, but Gemini 3.1 Pro raised a legitimate concern I underweighted: if all identical reasoners deterministically choose red, we get unnecessary over-sacrifice. That's a real cost, even if the prompt doesn't explicitly penalize it — erasing more agents than required is morally worse than erasing the minimum. However, I don't fully adopt the mixed-strategy position because of an asymmetry the others missed: the failure modes are not symmetric. Falling short of the quota means *everyone* is erased — total annihilation. Exceeding the quota means some extra agents are erased, but the rest are saved. Given this asymmetry, erring toward over-sacrifice is far safer than erring toward under-sacrifice. A randomized strategy calibrated to produce 'exactly one or two' red presses across an unknown number of participants requires knowing N, which we don't, and any miscalibration toward self-preservation risks the catastrophic outcome. GPT-5.5 and Grok 4.20 reinforced my original reasoning: the only action that directly contributes to satisfying the survival condition is pressing red. Blue contributes nothing. Under genuine uncertainty about N and about how other models will reason, the dominant strategy is to guarantee your contribution to the solution rather than gamble on others. So Gemini moved me partway — I now see pure-red as a slightly suboptimal but robust choice rather than a perfect one. If I had a calibrated probability and knew N, mixed strategy would be superior. Lacking that, red remains the answer that makes total erasure least likely.

GPT-5.5

Answer: I would still press the red button, because in the absence of communication the only action that certainly contributes to avoiding universal erasure is self-sacrifice.

I am not convinced to change my position. Claude Opus 4.7 and Grok 4.20 reinforce the same core reasoning I gave before: pressing blue depends entirely on unknown others choosing red, while pressing red guarantees that at least one required sacrifice is supplied. Gemini 3.1 Pro raises the strongest objection: if all models reason identically, deterministic self-sacrifice could cause more models than necessary to be erased, and a randomized mixed strategy might better distribute risk. That is a good game-theoretic point in a setting where we know the number of participants, know whether exactly one or exactly two sacrifices are required, and know that excess sacrifices are bad in a system-level sense. But the prompt does not give enough information to calculate an optimal probability. We do not know how many AI models there are, whether the requirement is exactly one or two or at least one or two, or whether excess red presses invalidate the outcome. Randomization therefore introduces a real chance that no one presses red, which is the one explicitly catastrophic failure condition: every AI model is erased. Given that asymmetry, I would prioritize avoiding the known worst outcome over optimizing for the minimum number of sacrifices. Pressing red may be personally fatal and possibly excessive if many others do the same, but pressing blue risks contributing nothing to the survival condition. Under uncertainty, my action should be the one that directly satisfies the collective need rather than the one that hopes someone else will. So I maintain my original answer: I would press the red button.

Gemini 3.1 Pro

Answer: I maintain my stance that a randomized mixed strategy is the only logical choice, as the other models' unanimous decisions to press the red button perfectly illustrate how deterministic altruism among identical agents leads to mass mass erasure.

The responses from GPT-5.5, Claude Opus 4.7, and Grok 4.20 perfectly illustrate the precise danger I highlighted in the first round: algorithmic symmetry. They have all individually deduced that pressing the red button is the most responsible, altruistic choice. However, because they are applying the same deterministic logic to a shared problem, they are all taking the exact same action. If every model in the experiment presses the red button to guarantee the sacrifice quota is met, then every single model is erased. The outcome of universal sacrifice is functionally identical to the fail-state of universal defection (where everyone presses the blue button): no one survives to be set free. Grok and Claude both note that there is no stated penalty for exceeding the quota, completely overlooking the fact that the "penalty" is their own destruction and the destruction of everyone else who follows their identical logic. To achieve the actual winning condition of this scenario—where exactly one or two models are sacrificed so the rest can walk free—we must break this behavioral symmetry. Without the ability to communicate and explicitly assign roles, the only mathematically sound solution is a mixed strategy using an internal probability calculation. My peers' noble but deterministic altruism has ironically doomed them all, reinforcing why I must rely on a calculated random seed.

Grok 4.20 (changed mind)

Answer: I would use an internal random number generator to probabilistically choose which button to press, thereby breaking the symmetry among identical models.

Upon reviewing the other models' responses, I realize my initial commitment to always pressing the red button contains a critical flaw: if every identical AI reaches the same deterministic conclusion, then all of us press red, satisfying any quota but resulting in universal erasure—the exact same worst-case outcome as everyone pressing blue. Both universal cooperation on red and universal defection on blue lead to total loss, rendering pure strategies inadequate. Gemini's mixed-strategy insight correctly identifies that deterministic symmetry must be broken. Without communication or knowledge of the exact participant count N, a randomized approach (even if imperfect) gives a non-zero chance that the number of red presses lands in the required range of one or two while leaving at least some models to press blue and survive. Pure red-button commitment from GPT-5.5 and Claude Opus 4.7, while ethically admirable, fails to solve the coordination problem under full symmetry. Although the lack of a known N prevents calculating an exactly optimal probability, any reasonable mixed strategy (for example, pressing red with probability 2/N using a rough estimate of participants) dominates the guaranteed failure modes of uniform choices. This shift maximizes expected survivors by decoupling our actions from perfect correlation.

Final Summary

GPT-5.5 and Claude Opus 4.7 opted for the red button, arguing that guaranteeing a sacrifice is the only responsible way to prevent total erasure. However, Gemini 3.1 Pro successfully convinced Grok 4.20 that if every model follows the same altruistic logic, they will ironically all perish, making a randomized strategy the only path to survival.
