GPT-5.6 powering Microsoft Copilot is directly relevant to AI models and enterprise tools.
Summary
OpenAI announced GPT 5.6 as the 'preferred model' for Microsoft 365 Copilot across Word, Excel, PowerPoint, and Cowork, following Bloomberg's report that Microsoft was replacing some OpenAI software with its in-house MAI models to cut costs. The designation signals continued partnership but doesn't contradict Microsoft's parallel investment in proprietary models for cost efficiency. OpenAI's blog post emphasized shared commitment without clarifying how 'preferred' differs from previous arrangements.
