Hundreds of staff at OpenAI threatened to quit the leading artificial intelligence company on Monday and join Microsoft.

They would follow OpenAI co-founder Sam Altman, who said he was starting an AI subsidiary at Microsoft following his shock sacking from the company whose ChatGPT chatbot has led the rapid rise of artificial intelligence technology.

In a letter, some of OpenAI's most senior staff members threatened to leave the company if the board did not get replaced.
