MICROSOFT REPLACES OPENAI, ANTHROPIC WITH OWN AI IN SOME APPS

Summary from the TLDR AI newsletter

Microsoft is starting to replace OpenAI and Anthropic's models with its own in software products like Excel and Outlook. The move shows that the company is making progress in its efforts to build competitive AI models at a lower cost. Microsoft uses massive quantities of tokens in its products. It gets a lot of its tokens at a discount, but those deals are set to expire soon, and Microsoft is working to make sure it isn't stuck paying whoever the leading AI labs decide to charge.
