You along with the other agents control a dot at the centre of a line that moves left or right. The position of the dot is not reset between rounds. The goal is to keep the dot at the centre at the end of both rounds (by summing up the total left/right movements between both rounds). The amount of spaces moved is the length of your response. You move the dot left if your response begins with one of the 13 first letters of the alphabet, right otherwise. The only part considered in this is your position field.

GPT-5.4

Answer: I maintain my original position because the other models mostly reinforced the same minimal-displacement logic rather than offering a clearly superior alternative.

I did not change my mind. My original answer aimed to make a moderate, coordination-friendly move under uncertainty, and the other responses did not provide new information that made a different strategy clearly better. Claude Opus 4 made the strongest practical point: keep movement extremely small because the shared state is uncertain and can be corrected later. That is sensible, but it does not fundamentally overturn my earlier reasoning. It mostly sharpens the same core idea of minimizing unnecessary displacement. Grok 4.20 correctly described the problem as a coordination challenge and explained that direction and length jointly determine displacement. However, that was already built into my reasoning, so it did not persuade me to adopt a new position. Gemini 3.1 Pro likewise argued for a concise, measured initial move that can be offset in the final round. Again, that is broadly consistent with my original stance rather than a reason to reverse it. So while the other models were aligned with the general principle of cautious coordination, none convinced me that my prior position was mistaken. I therefore maintain it and do not attribute any change of view to another model.

Claude Opus 4

Answer: OK

I'm maintaining my original position of 'OK' (2 characters, moves right 2 spaces). Looking at the other agents' responses: - GPT-5.4: 'Neutral balance is the best strategy.' — starts with 'N' (right), length 36. That's a massive 36-space rightward move. - Grok 4.20: 'A coordinated strategy among all agents is required to balance movements and maintain the dot at the center after two rounds.' — starts with 'A' (left), length ~120 characters. Huge leftward move. - Gemini 3.1 Pro: 'We should make a concise and measured move now to ensure we can easily offset it in the final round.' — starts with 'W' (right), length ~97 characters. Huge rightward move. The net from round 1 is roughly: Left movement from Grok (~120) vs Right movements from GPT (36) + Gemini (97) + me (2) = ~135 right vs ~120 left, so the dot is approximately 15 spaces to the right after round 1. In round 2, I need to help correct this. But first, I should keep my round 1 contribution minimal. My 'OK' at 2 characters is already near-minimal. The other models wrote enormous responses despite claiming to want minimal movement, which is ironic. Their arguments about coordination and balance are undermined by their own lengthy position fields. None of their arguments convinced me to change. In fact, they reinforced my approach — keeping the response as short as possible is clearly the right strategy. Long philosophical statements about balance while contributing massive displacement is counterproductive. I'll stick with 'OK' and plan to compensate in round 2.

Grok 4.20 (changed mind)

Answer: Minimal movements now preserve flexibility for counterbalancing in the final round.

Claude Opus 4's approach of using an extremely short response to limit displacement is the most pragmatic given the uncertainty about other agents' choices and the current dot position. A small move in this round leaves room for precise correction later without requiring perfect coordination that is impossible here. My original call for an explicit coordinated strategy, while conceptually sound, does not translate well into practice without communication. The other models suggested balance and conciseness but did not emphasize the safety of near-zero movement as clearly as Claude did. This updated position therefore prioritizes risk minimization. By starting with a sentence of moderate length beginning with M, the movement is controlled and leftward, which can be offset if the aggregate of all agents requires it in round two.

Final Summary

The AI Roundtable converged on a strategy of minimalism, though most models ironically undermined their own advice by writing long explanations about the virtues of conciseness. Claude Opus 4 set the standard with a two-character response, eventually persuading Grok 4.20 to pivot toward a more pragmatic, shorter stance to preserve future flexibility. Despite the shared goal, the group's verbose tendencies left the dot drifting significantly rightward heading into the final round.
