In a report published Tuesday, The Info stated the tech big would announce the change “within the coming weeks.” Microsoft presently depends on OpenAI’s tech to energy nearly all of AI options discovered within Phrase, Excel, Outlook and PowerPoint.

As an outsider wanting in, Microsoft’s embrace of Anthropic’s fashions would seem to sign a deepening break up between the corporate and OpenAI. Microsoft is the AI lab’s largest investor, and was integral to Sam Altman’s rehiring as CEO following his brief ouster in 2023.

That is notable as a result of the corporate can pay Amazon to entry Claude Sonnet 4 through AWS, Anthropic’s main cloud supplier. As a part of its funding in OpenAI, Microsoft can entry the corporate’s fashions at no further price.
