OpenAI president disputes Musk's claims in trial, revealing secret Tesla work and heated boardroom clashes.

OpenAI President Greg Brockman concluded his testimony in the ongoing Musk vs. Altman trial by disputing Elon Musk's version of OpenAI's early days and corporate structure. Brockman emphasized that OpenAI remains a nonprofit and revealed that Musk had OpenAI employees secretly work on Tesla's self-driving technology in 2017. The trial centers on Musk's lawsuit accusing OpenAI leaders of breaking their nonprofit vow, with Musk also alleging attempts to "steal a charity." Brockman described Musk as a polarizing figure who was often unavailable, and recounted a heated boardroom incident where Musk reacted angrily to equity negotiations. The trial will continue with further testimonies soon.
