Aug 5 (Reuters) - John Schulman, one of the co-founders

of artificial intelligence company OpenAI, has left the ChatGPT

maker for rival Anthropic, he said in a post on social media

platform X late Monday.

"This choice stems from my desire to deepen my focus on AI

alignment, and to start a new chapter of my career where I can

return to hands-on technical work," Schulman said in his X post.

OpenAI's President and co-founder Greg Brockman is also

taking a sabbatical through the end of the year, he said in a X

post late Monday.

The news was first reported by The Information, which added

that Peter Deng, a product manager who joined OpenAI last year,

has also exited the company.

OpenAI did not immediately respond to a Reuters request for

comment.

The move comes as OpenAI faces significant personnel

changes, with the company's AI safety leader Aleksander Madry

being reassigned to another role in July.

Another one of OpenAI's co-founders and chief scientist,

Ilya Sutskever, left the company in May. Andrej Karpathy, who

was also one of the AI firm's founding members left OpenAI in

February and started an AI-integrated education platform in

July.

Tesla CEO Elon Musk, who was also one of the co-founders of

OpenAI and left three years later, revived his lawsuit against

the company and CEO Sam Altman on Monday, saying that the firm

put profits and commercial interests ahead of public good.
