Microsoft first invested $1 billion into OpenAI in 2019, and has had a close relationship with the ChatGPT creator ever since. Semafor is now reporting that Microsoft is eyeing a $10 billion bet on OpenAI that would see the software giant get 75 percent of profits and a 49 stake in OpenAI. The rumors come days after reports that Microsoft is planning to integrate OpenAI models into Bing, Word, and more.
