Microsoft Partners with Anthropic to Enhance Office 365 AI

Microsoft is reportedly collaborating with Anthropic to power its Office 365 Copilot, moving away from OpenAI's technology. The shift aims to integrate Anthropic's Claude models, which outperform OpenAI's GPT-5 in some tests. This transition will only partially implement Claude in select Office apps. Despite this, Microsoft will maintain its partnership with OpenAI for other technologies.
