Twitch co-founder, Emmett Shear, has confirmed his appointment as OpenAIโ€™s new CEO on Monday, days after the AI firm fired Sam Altman.

โ€œToday I got a call inviting me to consider a once-in-a-lifetime opportunity: to become the interim CEO of @OpenAI. After consulting with my family and reflecting on it for just a few hours, I accepted,โ€ he said in a post on X, formerly Twitter.

OpenAIโ€™s board sacked its former CEO Altman on Friday, prompting other high-profile departures from the company as well as a reported push by major investors to bring the co-founder back.

In his post, Shear denied that Altman had been fired over safety concerns.

โ€œBefore I took the job, I checked on the reasoning behind the change. The board did not remove Sam over any specific disagreement on safety, their reasoning was completely different from that,โ€ he wrote.

โ€œIโ€™m not crazy enough to take this job without board support for commercializing our awesome models.โ€

An hour before Shearโ€™s post, Microsoft CEO Satya Nadella confirmed he was hiring Altman to lead an AI research team at the global tech titan.

โ€œWe look forward to getting to know Emmett Shear and OAIโ€™s new leadership team and working with them,โ€ Nadella added in a post on X.
