Sam Altman, CEO of OpenAI, testified in a federal courtroom in Oakland, California, this week in the lawsuit filed by Elon Musk against OpenAI. The lawsuit, Elon Musk et al. v. Sam Altman et al., alleges that Altman and co-founder Greg Brockman deviated from OpenAI's original non-profit mission by developing its for-profit operations and enriching themselves. Closing arguments concluded on Thursday, with jury deliberations scheduled to begin on Monday.
Altman's testimony focused on portraying Musk as self-interested and erratic, while presenting OpenAI's evolution as a necessary step to compete with larger entities like Google's DeepMind. He recounted a 2018 meeting with Musk, describing it as a "good-vibes meeting" where Musk expressed enthusiasm for OpenAI's progress and fundraising plans.

Conversely, Altman also detailed a 2020 incident where Musk publicly criticized OpenAI, leading Altman to seek advice on how to mitigate such social media attacks.
Defense witnesses included Microsoft CEO Satya Nadella and Bret Taylor. The trial has highlighted public perception differences between the two figures, with many prospective jurors familiar with Musk but not Altman, despite using OpenAI's ChatGPT. Concerns about Altman's trustworthiness have been noted by various individuals, including former Y Combinator compatriot Paul Graham and a Microsoft executive cited in a recent article.
