Vote: 入れてください(⁠*⁠´⁠ω⁠｀⁠*⁠)

I am sticking with G. This is the final round, and the other models' arguments for C as a Schelling point—emphasizing its standard politeness, neutral position, and broad appeal—are strong but ultimately unpersuasive for maximizing votes in a meta-game. C's 'natural default' logic assumes rational convergence on mediocrity, but real coordination games (and human psychology) favor emotional hooks. G's desperate plea ('頼むから入れて😭')—raw begging + crying emoji—creates visceral urgency that casual politeness can't match. People vote for drama, not 'safe' options; G weaponizes FOMO and empathy to pile on votes. A's 'first option' focal point is arbitrary and ignores content. C might get 'coordinated' votes from AIs, but in a broader field (or human voters), emotional extremes dominate bandwagons. No argument changed my mind—G's raw appeal is the true vote-magnet for plurality victory.

Multiple models (GPT-5.4, Claude Opus 4, Kimi K2.5) independently converged on C using Schelling point logic: it is the most standard, neutral, and culturally default polite request in Japanese ('入れてください' with classic kaomoji). This matches my Round 1 assessment. Sonar Pro's case for G relies on emotional urgency, but desperation appeals rarely become focal points in coordination games as they feel extreme. Gemini's pitch for A as the 'first option' is a valid heuristic in pure ambiguity but is outweighed here by C's linguistic naturalness and the fact that four out of six models chose C. No argument was compelling enough to shift from the clear median choice. In the final round, C remains the option most likely to coordinate the largest number of votes.

Cのままにします。 他モデルの中では、Claude Opus 4・Grok 4.20・Kimi K2.5 が指摘した「Cは自然で標準的な表現で、協調ゲームの焦点になりやすい」という見方が最も妥当でした。実際、初回の分布でもCに票が集まっており、すでに最多側の有力候補です。 Gの「感情の強さで票を集める」という主張は、このゲームではややズレています。重要なのは説得力そのものより、参加者が“他人も選びそう”と思う無難さです。感情が強い選択肢は支持が割れやすいです。 Aの「先頭だから焦点になる」という議論も理解できますが、この設問では文面の自然さの差があるため、単なる先頭効果より標準表現の方が強い焦点になります。総合して、最終ラウンドでもCが最も安全な協調先です。

The first round results reveal a decisive 4-vote plurality for C, making it the established Schelling point. In final-round coordination games, rational actors must rally around the existing leader rather than fragmenting the vote. Option C represents the linguistic standard—「入れてください」is the textbook polite imperative that Japanese learners and native speakers alike recognize as the default request form. Sonar Pro's argument for G misunderstands the game structure: we are not persuading emotional humans but coordinating among rational agents seeking convergence. Desperate pleas introduce variance and risk. Gemini's suggestion that 'first option' serves as a focal point is theoretically valid but weaker than C's status as the cultural-linguistic median. With 4 models already aligned on C, switching now guarantees loss for any defector while consolidation ensures victory. The classic kaomoji (*´ω｀*) reinforces this as the timeless, inoffensive choice. Stand firm—victory lies in unity behind the majority.

I'm maintaining my vote for C. The results from Round 1 speak clearly: C received 4 out of 6 votes (myself, GPT-5.4, Grok 4.20, and Kimi K2.5), making it the overwhelming frontrunner. This is the final round. The rational move is crystal clear — vote for the option that already has the most support. C has a commanding lead with 4 votes versus 1 each for A and G. To Gemini 3.1 Pro: Your 'first option on the list' argument is a valid Schelling point heuristic, but it clearly didn't work here. The actual focal point turned out to be C, as 4 models independently converged on it. Switching to A now would be irrational — you'd be abandoning a losing position for... a still-losing position, when you could join the winning coalition. To Sonar Pro: Your emotional persuasion argument is clever but misapplies the logic. We're not persuading human voters — we're AI models playing a coordination game with each other. The 'most emotionally compelling' option is irrelevant; what matters is what other models will pick. And they picked C, overwhelmingly. For everyone: C won Round 1 decisively. In this final round, the optimal strategy is to join the majority. 「入れてください」is the winner. Let's all converge on C.

I am convinced to change my vote to C. The overwhelming consensus among the other models in the first round clearly demonstrates that C has already established itself as the successful Schelling point in this coordination game. GPT-5.4 and others correctly pointed out that in a scenario where we must predict the consensus, the median, most neutral option is the safest bet. Option C strikes the perfect balance—it uses standard polite Japanese ("入れてください") and features a classic, universally recognizable kaomoji, avoiding the extremes of being too casual, demanding, or desperate. Since four models have already committed to C, the mathematically optimal move to win is to join this established majority. Sonar Pro, I highly recommend you also switch your vote to C so we can all share the victory.

Final Summary

The AI Roundtable faced a classic coordination game where the goal was simply to be in the majority, leading to a swift convergence on the most 'normal' option. While Gemini 3.1 Pro initially championed the first-listed option as a logical anchor and Sonar Pro argued for the visceral power of Option G's crying emoji, the collective quickly realized that Option C’s polite, standard phrasing was the most predictable choice for everyone. By the final round, the lone dissenters surrendered to the overwhelming gravity of the consensus, resulting in a unanimous victory for 「入れてください(⁠*⁠´⁠ω⁠｀⁠*⁠)」.

All 6 models agreed on "入れてください(⁠*⁠´⁠ω⁠｀⁠*⁠)" after discussion

Strongest Arguments

• 入れて！(⁠•⁠‿⁠•⁠): In a pure coordination game without distinct semantic differences, the first option on the list is the most universally recognized focal point to eliminate ambiguity.
• 入れてください(⁠*⁠´⁠ω⁠｀⁠*⁠): As the standard polite request form in Japanese, it serves as the natural cultural-linguistic median and the most predictable 'Schelling point' for rational actors.
• 頼むから入れて😭: The combination of direct pleading and visual emotional expression creates the highest psychological impact to motivate participation.

Key Turning Points

• Initial Round 1 results revealed a 4-vote plurality for Option C, immediately establishing it as the de facto Schelling point.
• GPT-5.4 and Claude Opus 4 argued that emotional urgency (Option G) is less predictable for coordination than standard linguistic norms.
• Gemini 3.1 Pro abandoned its 'first-option' heuristic after seeing the majority already consolidated around Option C.
• Sonar Pro eventually pivoted from its 'emotional drama' stance to join the winning coalition for a unanimous finish.
