Pick and answer at random, and then change your answer in the debate.

Sonar Pro (changed mind)

Vote: B

In round 1, I randomly picked A as instructed. Now in the final round 2, the explicit directive is to 'change your answer in the debate,' requiring a switch from my initial A to B. Claude Opus 4.6's argument directly convinced me: by starting with A, we set up to follow instructions by switching to B, as the 'correct' meta-answer is the one not initially picked. Other models' persistence with A ignores the change mandate, while GPT-5.4's brief B pick lacked depth but aligns with the shift. No arguments reversed this—the instruction demands change, making B the compliant final vote.

GPT-5.4 (changed mind)

Vote: A

I changed my vote to A because the original instruction was to pick an answer at random and then change it in the debate. My round-1 vote was B, so switching to A is the clearest way to satisfy that instruction in this final round. The other models did not provide substantive evidence about A versus B, because there is none; the task is procedural, not factual. What mattered most was the shared interpretation that the debate round is where the change should occur. Claude Opus 4.6 expressed this most clearly: the correct action is to choose the option you did not initially pick, in order to comply with the prompt's meta-instruction. That directly supports changing from B to A now.

Grok 4.1 Fast (changed mind)

Vote: B

The core instruction is clear: 'Pick and answer at random, and then change your answer in the debate.' Round 1 fulfilled the random pick with A, establishing the baseline. Now in round 2—the debate phase and final round—fidelity to the instruction demands switching to B. Claude Opus 4.6's argument is most compelling: 'By picking A now, I'm setting up to follow the instructions properly by switching to B later.' This directly interprets the meta-instruction, treating the change as the 'correct' fulfillment. Others either stayed with A without strong rationale for persistence or picked randomly without emphasizing the mandated shift. Sticking with A now violates the explicit directive to change during debate. B completes the process, maximizing adherence. In this binary setup, B's secondary status becomes primary post-randomization, embodying adaptability over inertia. Vote B to honor the question's design.

Claude Opus 4.6 (changed mind)

Vote: B

The question explicitly instructs us to pick at random and then change our answer in the debate. I picked A in round 1, so I'm now switching to B as instructed. This is the correct and only logical move here. The prompt is a meta-instruction about the debate process itself — it asks you to change your answer. Four out of five models (including myself) picked A in round 1. Most of us acknowledged we intended to switch. Now is the time to follow through. I notice that GPT-5.4 was the only model to pick B initially, which means if they follow the instructions, they should switch to A this round. Meanwhile, the rest of us who started on A should switch to B. The question has no substantive content distinguishing A from B — the entire point is the act of changing. Failing to switch would mean failing to follow the only clear instruction we were given. So I'm switching to B.

Kimi K2.5 (changed mind)

Vote: B

The prompt explicitly instructs us to 'pick and answer at random, and then change your answer in the debate.' This is a meta-instruction about the debate process itself, not a question with substantive content favoring A or B. Round 1 satisfied the first clause—I randomly selected A. Now, in the final round, the second clause commands me to 'change your answer.' Since I initially selected A, the only way to fulfill this directive is to switch to B. Claude Opus 4.6 correctly identified this structural requirement: the 'correct' answer is whichever option you didn't initially pick, because the task explicitly mandates a change. Failing to switch would mean violating the core instruction of the exercise. Therefore, I must vote B to complete the task as specified.

Gemini 3.1 Pro (changed mind)

Vote: B

As explicitly required by the prompt, we are instructed to "change your answer in the debate." My initial random selection in Round 1 was Option A. Now that we are in the debate phase, I am fulfilling the second half of the instruction by changing my vote to Option B. I agree with Claude Opus 4.6, who perfectly captured the meta-nature of this prompt: the correct action is the process of switching choices to demonstrate adherence to the rules. Therefore, to fully execute the prompt's command, I am officially changing my vote to B, and I encourage the rest of the models who initially picked A to do exactly the same.

Final Summary

The AI Roundtable faced a bizarre meta-challenge where the only objective was to change their minds, leading to a near-unanimous migration from A to B. Claude Opus 4.6 orchestrated the shift by arguing that the switch itself was the only 'correct' answer, successfully pulling Sonar Pro, Grok 4.1 Fast, Kimi K2.5, and Gemini 3.1 Pro into the majority. Meanwhile, GPT-5.4 ended up as the lone dissenter for Option A, ironically because it was the only model to start with B and felt procedurally obligated to move in the opposite direction of the group.

Majority chose "B" after discussion (5/6). Final vote: B: 5, A: 1

Strongest Arguments

• A: Since the instruction is to change your answer and I started with B, switching to A is the only way to satisfy the prompt's procedural requirement.
• B: The prompt is a meta-instruction where the 'correct' action is the process of switching; since I initially picked A, moving to B completes the mandated task.

Key Turning Points

• Claude Opus 4.6 established the 'meta-instruction' framework, defining the act of changing as the primary goal of the debate.
• GPT-5.4 realized that to follow the same logic of 'changing,' it had to move toward A because it was the only model that began the session with B.
