OpenAI Co-Founder Returns to Startup After Monthslong Leave

OpenAI co-founder Greg Brockman has returned to the artificial intelligence startup three months after taking a leave from his role as president, bringing a key figure back to the C-suite amid an exodus of top executives.

Brockman announced he has officially started working again at OpenAI in an internal memo to staffers on Tuesday, according to a person familiar with the matter, who spoke on condition of anonymity to discuss company matters. In his memo, Brockman said he has been working with Chief Executive Officer Sam Altman on creating a new role for him to focus on significant technical challenges.
