(Bloomberg) — OpenAI Chief Executive Officer Sam Altman rebuffed Elon Musk’s $97.4 billion offer to take control of the artificial-intelligence startup for the second time in less than a day, accusing the world’s richest man of making the bid just to gain a competitive advantage.

“I think he is probably just trying to slow us down. He obviously is a competitor,” Altman said in an interview with Bloomberg Television Tuesday on the sidelines of the Paris AI summit. “I wish he would just compete by building a better product, but I think there’s been a lot of tactics, many, many lawsuits, all sorts of other crazy stuff, now this.”
