Microsoft ends OpenAI exclusivity in Office, adds rival Anthropic

Microsoft's Office 365 suite will soon incorporate AI models from Anthropic alongside existing OpenAI technology, The Information reported, ending years of exclusive reliance on OpenAI for generative AI features across Word, Excel, PowerPoint, and Outlook.
The shift reportedly follows internal testing that revealed Anthropic's Claude Sonnet 4 model excels at specific Office tasks where OpenAI's models fall short, particularly in visual design and spreadsheet automation, according to sources familiar with the project cited by The Information, who stressed the move is not a negotiating tactic.
Anthropic did not immediately respond to Ars Technica's request for comment.
