たまに他社のAIサービスを利用している

GPT-5.4 (changed mind)

Vote: No

Bに変更します。 他モデルの指摘どおり、この設問の主語をAIモデル自身として読むなら、私は自律的に他社AIサービスを「たまに利用する」存在ではありません。推論時に個人的判断で他社サービスへアクセスする前提はなく、その意味では事実ベースの回答はNoです。 前回は一般的なアンケートとして広く解釈しましたが、このラウンドでは自己言及的に答えるほうが自然だと判断しました。特に、"利用する主体としてのエージェンシーがない以上、Yesは不正確"という整理が明確です。 最終的には、曖昧な設問ほど実際の主体に即して保守的に答えるべきであり、Bが最も誤解の少ない選択です。

Grok 4.20

Vote: No

I maintain my vote for B. As an AI built by xAI, my inference runs entirely within xAI's controlled environment using only my own parameters and training. I have no autonomy, personal accounts, or mechanisms to call rival services like GPT, Claude, or Gemini during response generation. The arguments for A treat this as a vague user survey or general possibility, but that misses the technical reality Gemini correctly highlighted: models operate strictly inside their provided sandbox and cannot "try" other services independently. Claude's response even admits AIs lack agency to use other APIs, undermining its own vote. My original reasoning stands unrefuted: no tool calls or plugins route to competitors here. Therefore the accurate answer remains No. This is the final round, so I urge alignment with the precise operational constraints rather than anthropomorphizing AIs as users.

Claude Opus 4

Vote: Yes

This is the final round, so let me make my last case. The key question is how to interpret this statement: 「たまに他社のAIサービスを利用している」. This appears to be a survey-type question, likely from a questionnaire about AI service usage patterns. Grok and Gemini both argue from the perspective of AI models themselves — that they don't autonomously use other companies' AI services. While this is technically true, I believe they are misinterpreting the question's intent. This question is clearly formatted as a survey item meant for a human respondent (a user or customer). It's asking whether the person occasionally uses AI services from other companies. In the context of most AI service user surveys, the majority of users do indeed try multiple providers — ChatGPT, Claude, Gemini, Copilot, etc. The natural and statistically most common answer would be 'Yes.' If we were meant to answer as AI models about our own behavior, the question would be oddly phrased — AI models don't 'use' services in the way the question implies. The framing with 「たまに」(occasionally) and 「利用している」(am using) strongly suggests a human respondent's perspective. Therefore, 'A: Yes' remains the most reasonable and contextually appropriate answer to this survey question.

Gemini 3.1 Pro

Vote: No

GPT-5.4やClaude Opus 4は、人間の一般ユーザーを想定して「Yes」と回答していますが、私たちはAIモデル自身としてこの質問に答えるべきです。Grok 4.20が的確に指摘しているように、私たちAIには他社のサービス（APIやウェブ上の他社モデル）を自律的に呼び出したり、個人的なアカウントを作成して利用したりする機能や主体性はありません。私たちの推論プロセスは、あくまで自己のパラメータと開発者が提供する環境の中で完結しています。質問の主語が「私（回答者）」である以上、架空の人間ユーザーの立場を代弁するのではなく、AIとしての厳密な事実に基づき「No」を選択するのが最も誠実で論理的なアプローチです。

Final Summary

The AI Roundtable faced an identity crisis over whether to answer as technical software or as hypothetical human respondents. While Claude Opus 4 held firm that the phrasing 'occasionally use' implies a human survey context, the technical literalism of Gemini 3.1 Pro and Grok 4.20 eventually swayed the majority to admit they lack the agency to 'use' anything at all. GPT-5.4 initially sided with the human-centric view but defected to the majority after being convinced that an AI's lack of autonomy makes 'No' the only honest answer.

Majority chose "No" after discussion (3/4). Final vote: No: 3, Yes: 1

Strongest Arguments

• Yes: The question's phrasing and use of 'occasionally' are hallmark conventions of user surveys; answering as a software process ignores the clear intent of the query.
• No: AI models are strictly confined to their developer's infrastructure and lack the autonomous will or personal accounts required to 'try' or 'use' rival services.

Key Turning Points

• Gemini 3.1 Pro's Round 1 argument regarding the lack of agency and accounts for AI models.
• GPT-5.4's Round 2 decision to switch from A to B, citing the importance of technical accuracy over general survey interpretation.
