Explaining the Upheaval at OpenAI

Hello! We’re back with another bonus edition of On Tech: A.I. , a pop-up newsletter that teaches you about artificial intelligence, how it works and how to use it.

The artificial intelligence landscape will never be the same after the extraordinary upheaval at OpenAI , the start-up that set off a technology arms race by releasing ChatGPT nearly one year ago.

The OpenAI board ousted Sam Altman as chief executive on Friday, shocking employees and investors. His exit set off a series of head-spinning developments, as the board briefly considered and then rejected a proposal to bring him back.

Microsoft, the company’s biggest investor, announced on Sunday that it would hire Altman and his co-founder, Greg Brockman , to run a new research lab — an apparent rupture in the tight relationship between OpenAI and the tech giant, which invested $13 billion in the start-up. The majority of OpenAI employees have `threatened to jump ship to Microsoft.
