A former OpenAI leader who resigned from the company earlier this week said on Friday that safety has “taken a backseat to shiny products” at the influential artificial intelligence company.

Jan Leike, who ran OpenAI’s “Super Alignment” team alongside a company co-founder who also resigned this week, wrote in a series of posts on the social media platform X that he joined the San Francisco-based company because he thought it would be the best place to do AI research.
