Microsoft、コスト削減のためMAI-1を採用――ただしGPT-5.6は依然「優先」
OpenAIはGPT-5.6をMicrosoft 365 Copilotの優先モデルとして指定し、Microsoftがコスト削減のため自社製MAIモデルへ切り替えているという報道に反する結果となりました。
openai announced that gpt-5.6 is the preferred model for microsoft 365 copilot, powering productivity apps like word, excel, and powerpoint. this statement directly addresses bloomberg reports that microsoft was increasingly deploying its own internal mai models to reduce dependency on openai and lower costs. although the partnership is reaffirmed, the terminology implies a shared ecosystem rather than an exclusive lock-in, signaling that microsoft is likely hedging its strategy with proprietary models.
