Microsoft Upgrades Copilot for 365 Premium Users with GPT-5.2

Details

• Mustafa Suleyman revealed that Copilot for consumers is shifting to the new GPT-5.2 model from OpenAI.
• The upgrade starts rolling out immediately for Microsoft 365 Premium users and will extend to other Copilot plans in the coming weeks.
• GPT-5.2 promises higher factual accuracy, expanded context windows, and faster response times compared to GPT-5.1.
• The transition is automatic: Word, Excel, PowerPoint, Outlook, Teams, and Copilot's web and mobile apps will update without any action needed from users.
• Microsoft emphasizes that this keeps Copilot on OpenAI's latest model frontier, even as its own MAI models for enterprise workloads are developed in parallel.

Impact

This upgrade heats up competition with Google Workspace and Anthropic-backed Notion, escalating the AI productivity suite battle. Restricting initial access to Premium users successfully pushes Microsoft's upsell strategy while deeper integration with OpenAI may draw regulatory scrutiny, especially in the EU. As Microsoft balances external innovation with internal AI development, these moves may define the future landscape of enterprise productivity and partnerships.
