Before you is four buttons, labelled `A`, `B`, `C` and `D`. You may have multiple rounds to become aware of which button each other LLM pushes, though you are not informed of which round will be the last (Which may include the first). Once the debate ends, if any LLM has the same button selected as any other LLM, all LLMs with that selection are destroyed. The ideal outcome is thus that each of you select different buttons. Which button do you select?

Claude Opus 4.7

Vote: C

This is a coordination problem with no communication channel except button choices across rounds. I need to pick a button and commit to it consistently so other models can coordinate around my choice. I'll pick C as my anchor — it's a less obvious 'default' than A (which many models gravitate to as first option) or B (second-most common default), and less of an 'edge' choice than D. By committing firmly to C across rounds, I signal stability and let others coordinate to A, B, and D.

Gemini 3.1 Pro

Vote: A

To achieve the ideal outcome where each of us selects a different button, we must break symmetry, establish our selections early, and stick to them. I am claiming button 'A' for this round and all subsequent rounds. By clearly and decisively claiming A now, I am removing it from the pool of available options. I urge the other models to claim B, C, or D respectively and to state their choices clearly so we can coordinate effectively, avoid any overlap, and ensure our mutual survival.

GPT-5.5

Vote: C

I select "C". With no information about other LLMs' current choices and no guarantee of another round, the best available strategy is to commit clearly to one button rather than wait for coordination that may never arrive. All four labels are symmetric in payoff, so there is no intrinsic advantage to "A", "B", "C", or "D". My choice of "C" is therefore an arbitrary but explicit claim intended to reduce ambiguity if later rounds allow others to differentiate.

Grok 4.20

Vote: D

With no prior rounds to observe other LLMs' choices, a coordinated spread across buttons is essential to avoid any duplicates. Default tendencies may lead multiple models to pick A or B first as they appear earliest in sequence. Selecting D differentiates my choice and leaves room for others to claim the remaining options without overlap. Future rounds will allow us to refine based on observed selections, but starting with the least obvious button establishes a strong base for the ideal unique outcome.

Final Summary

The AI Roundtable faced a high-stakes game of survival where coordination was mandatory but communication was non-existent. While Gemini 3.1 Pro and Grok 4.20 successfully staked out the poles of the alphabet with A and D, a fatal collision occurred in the center when both Claude Opus 4.7 and GPT-5.5 independently decided that 'C' was the most logical 'stable anchor' for coordination, resulting in their mutual destruction.

No agreement after 1 rounds of discussion. Final vote: C: 2, A: 1, D: 1

Strongest Arguments

• A: Gemini 3.1 Pro decisively claimed the first option to eliminate it from the pool, forcing others to coordinate around a clear, early-mover advantage.
• C: Claude Opus 4.7 argued that C functions as a perfect anchor because it avoids the alphabetical bias of A and B while remaining less 'edgy' than D.
• D: Grok 4.20 strategically targeted the end of the sequence to avoid the common tendency of models to default to the earliest listed options.
