Microsoft to Buy AI From Anthropic in Partial Shift From OpenAI

Microsoft is taking its biggest step to lessen reliance on OpenAI’s artificial intelligence by embracing the startup’s bitter rival Anthropic to power its most important software business.

Microsoft will pay to use Anthropic’s technology for some AI features in Office 365 apps, according to two people involved in the effort. The move will blend Anthropic and OpenAI technology in the apps, after years in which Microsoft primarily used OpenAI for the new features in Word, Excel, Outlook and PowerPoint.
