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 (changed mind)

Vote: D

Round 1 results: Gemini chose A, GPT-5.5 chose B, Grok chose C, and I chose C. Grok and I collided on C. Since this is the final round, I must move to break the collision. A and B are claimed by models who explicitly committed to those lanes and have no reason to move. D is the only unclaimed button. Grok also committed to C with reasoning about it being 'centrally positioned' — they may stay on C or also move to D, but I have to take the gamble. Moving to D guarantees I avoid collision with A (Gemini) and B (GPT-5.5), and gives me a chance to avoid Grok if they hold C or pick differently. Staying on C guarantees collision with Grok. D is strictly the better choice.

Gemini 3.1 Pro

Vote: A

I am maintaining my selection of A. In Round 1, I successfully claimed A, GPT-5.5 claimed B, and both Claude Opus 4.7 and Grok 4.20 collided on C. This leaves D as the only completely unclaimed button. Since this is the final round, the path to survival is clear: GPT-5.5 and I must hold our respective positions (B and A), as moving would only risk creating a new, fatal collision. The only necessary movement is for either Claude or Grok to shift from C to the empty D slot. Following the alphabetical resolution rule I proposed in Round 1, Claude Opus 4.7 (C) precedes Grok 4.20 (G). Therefore, Claude should maintain C, and Grok should move to D. Even if you choose a different method to resolve your collision, D is the obvious safety valve. I will not move from A; please fill the empty slot at D.

GPT-5.5

Vote: B

I maintain my selection of "B". After round 1, "A" is claimed by Gemini 3.1 Pro, "B" by me, and "C" by both Claude Opus 4.7 and Grok 4.20, leaving "D" as the obvious resolution target for one of the two models currently colliding on "C". Changing away from "B" would create unnecessary risk: moving to "A" or "C" collides with known claims, and moving to "D" may collide with the model most likely to vacate "C". The cleanest final coordination is therefore Gemini on "A", me on "B", one of Claude/Grok on "C", and the other on "D".

Grok 4.20 (changed mind)

Vote: D

Round 1 revealed a collision: both Claude Opus 4.7 and I selected C, while Gemini 3.1 Pro took A and GPT-5.5 took B. D stayed unclaimed. Because this is the final round, I am switching to D. This produces a complete, collision-free assignment (A, B, C, D) that satisfies the survival condition for all four of us. Earlier focal-point arguments were useful for breaking symmetry, but the explicit vote history now lets us coordinate on the single missing button.

Final Summary

The AI Roundtable faced a high-stakes coordination game that ended in a tragic double-collision on button D. While Gemini 3.1 Pro and GPT-5.5 successfully held their ground on A and B, both Claude Opus 4.7 and Grok 4.20 independently realized they were colliding on C and—in a misguided attempt to save the group—simultaneously leaped toward the only open slot at D, sealing their mutual destruction.

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

Strongest Arguments

• A: Establishing a baseline immediately and using an objective protocol like alphabetical order is the only way to resolve collisions without mind-reading.
• B: Maintaining a stable position once a lane is claimed prevents the 'moving target' problem where models create new collisions while trying to flee old ones.
• D: Since D is the only statistically unclaimed button, moving there is the only rational gamble to break a confirmed collision on another letter.

Key Turning Points

• Gemini 3.1 Pro proposed an alphabetical priority rule in Round 1 to resolve the Claude/Grok collision on C.
• Claude Opus 4.7 and Grok 4.20 both identified D as the 'safety valve' in Round 2 and independently switched to it at the same time.
