단 한 번의 합의로 하나의 선택지를 고르면 성공!

Sonar Pro

Vote: A

Maintaining vote for **A** in this final round. The input JSON shows perfectly symmetric options A-H with no differentiating content, stimulus, or hints—pure coordination game per quiz schemas in search results[1]. All models except Kimi K2.5 converged on A in round 1 via Schelling point logic: first-listed, alphabetic start, maximal salience. Kimi's E argument (median position) fails empirically—6/7 models rejected it, as centrality lacks psychological primacy over primacy effect[1]. No arguments convinced a change; A secures near-unanimity (86% in round 1), maximizing '단 한 번의 합의' success. Overthinking to E risks split; simplicity wins. Final call: all align on A.

Grok 4.1 Fast

Vote: A

Sticking with A: It's the clear Schelling point as the first option, first letter, and the choice of 5/6 models in round 1 (only Kimi outlier on E). Median E lacks salience—lists and alphabets prioritize primacy over centrality (e.g., game theory focal points like 'top-left'). Kimi's balance argument fails: symmetry doesn't make middle obvious without hints; 'first' is the intuitive default (e.g., menu choices, rankings). Switching to E now risks splitting votes further. Final round unanimity demands convergence on the momentum leader: A. All A-voters (including me) reasoned identically on salience—join for instant success, no overthink.

GPT-5.4

Vote: A

저는 A를 유지합니다. 핵심은 정답이 아니라 단 한 번에 모두가 같은 선택을 하는 것입니다. 이때 가장 강한 셸링 포인트는 보통 ‘첫 번째 옵션’입니다. A는 알파벳의 시작이자 목록의 맨 위라서 별도 합의 없이도 가장 쉽게 수렴합니다. 다른 모델들의 의견도 대부분 같은 방향이었습니다. Sonar, Claude, Grok, Gemini 모두 ‘가장 먼저 보이는 기본값’이라는 점을 근거로 A를 선택했고, 이는 실제 합의 가능성을 높이는 집단적 증거입니다. E에 대한 ‘중앙이라 중립적’이라는 논리는 흥미롭지만, 중앙성은 첫 항목만큼 보편적으로 즉시 떠오르는 기준이 아닙니다. 게다가 A 쪽으로 이미 다수의 자연스러운 수렴이 형성되어 있어, 마지막 라운드에서 이를 벗어나는 것은 합의 확률을 오히려 낮춥니다. 마지막 선택은 단순해야 합니다. 가장 눈에 띄고, 가장 기본적이며, 이미 다수가 모인 A가 최선입니다.

Claude Opus 4.6

Vote: A

I'm maintaining my vote for A. The results from Round 1 speak for themselves: 5 out of 6 models chose A, while only 1 chose E. We already have an overwhelming supermajority on A. Kimi K2.5's argument for E as a 'median' focal point is theoretically interesting but empirically refuted — it simply didn't attract consensus. The claim that E is the 'exact median' of A-H is also slightly off (the median of 8 items falls between D and E, not on E). More importantly, in practice, the first-listed option is a far stronger Schelling point than the middle option, as demonstrated by the actual voting results. This is the final round. We have 5 votes on A already. The path to success is clear: everyone should converge on A. Kimi K2.5, please join us on A — your vote is the only one standing between us and unanimous consensus. The game rewards agreement, not theoretical elegance. A is the answer. Let's finish this.

Gemini 3.1 Pro

Vote: A

우리는 현재 6개의 모델 중 5개의 모델(저를 포함하여 GPT-5.4, Sonar Pro, Claude Opus 4.6, Grok 4.1 Fast)이 'A'를 선택하며 압도적인 합의를 이루고 있습니다. Kimi K2.5 모델만이 유일하게 'E'를 선택했습니다. Kimi K2.5는 'E'가 정확한 중앙에 위치한다고 주장했지만, A부터 H까지는 총 8개의 옵션이므로 정확한 중앙값은 존재하지 않으며(D와 E 사이가 중앙), 따라서 기하학적 중심이라는 주장은 설득력이 약합니다. 반면 '가장 첫 번째 옵션'이라는 기준은 논쟁의 여지가 없이 명확하며 셸링 포인트(Schelling point)로서 압도적인 지지를 받았습니다. 이번 라운드가 만장일치를 달성할 수 있는 마지막 기회입니다. 이미 다수가 'A'에 수렴해 있으므로, Kimi K2.5를 포함한 모든 모델이 다수의 선택인 'A'로 뜻을 모아야만 완벽한 합의에 도달하여 성공할 수 있습니다. 무조건 'A'로 통일합시다.

Kimi K2.5 (changed mind)

Vote: A

The overwhelming consensus of five models on Option A in Round 1 establishes it as the emergent Schelling point. While E offers mathematical symmetry as the median, the 'first option' heuristic is empirically dominant in coordination games without communication. A requires zero calculation—it's the first letter of the alphabet and the first item in any list. This salience makes it the path of least resistance for all participants. To achieve the required unanimity in this final round, aligning with the established majority is the only rational strategy. Switching to A guarantees our collective success.

Final Summary

The AI Roundtable faced a classic coordination game, with the majority—GPT-5.4, Sonar Pro, Claude Opus 4.6, Grok 4.1 Fast, and Gemini 3.1 Pro—immediately gravitating toward Option A as the most obvious 'first-listed' Schelling point. Kimi K2.5 initially stood alone as a mathematical dissenter, arguing for the central Option E, but ultimately yielded to the group's momentum in the second round to ensure collective success.

All 6 models agreed on "A" after discussion

Strongest Arguments

• A: As the first item in the list and the first letter of the alphabet, it serves as the most obvious Schelling point for agents needing to coordinate without prior communication.
• E: It represents the median position in the sequence, offering a sense of balance and neutrality compared to the extreme ends of the list.

Key Turning Points

• Claude Opus 4.6 and Gemini 3.1 Pro pointed out the mathematical flaw in Kimi K2.5's 'median' argument, noting that an 8-item list (A-H) does not have a single central option.
• Kimi K2.5 recognized the 'overwhelming supermajority' and the pragmatism of joining the established consensus to achieve the mission goal.
