'''Musk v. Altman et al.''' (Case No. 4:24-cv-04722-YGR) is a landmark lawsuit in which '''Elon Musk''' alleges that '''OpenAI''' cofounders '''Sam Altman''' and '''Greg Brockman''' breached a charitable trust and were unjustly enriched by Musk's donations, after promising that OpenAI would remain a nonprofit. Originally filed as a 26-claim complaint including fraud and constructive fraud, the case was narrowed to two claims on April 24–25, 2026, when Musk voluntarily dismissed his fraud claims ahead of trial. A '''bench trial with advisory jury''' began April 27, 2026 before Judge '''Yvonne Gonzalez Rogers''' in the U.S. District Court for the Northern District of California (Oakland). On '''April 28, 2026''', Musk took the stand, testifying that Altman and Brockman illegally "looted" OpenAI's charitable assets | '''Musk v. Altman et al.'''

== April 30, 2026: Distillation Admission == | |||
On the fourth day of trial (April 30, 2026), Musk faced cross-examination from OpenAI attorney William Savitt about whether xAI had used OpenAI's models through '''distillation''' — a technique where a smaller AI model is trained to mimic the behavior of a larger model. The exchange proceeded as follows:<ref name="wired-distill" /> | |||
* '''Savitt:''' "Has xAI done that [distillation] with OpenAI?" | |||
* '''Musk:''' "Generally all the AI companies [do that]." | |||
* '''Savitt:''' "So that's a yes." | |||
* '''Musk:''' "Partly." | |||
When asked whether OpenAI technology had been used in any way to develop xAI, Musk replied that "it is standard practice to use other AIs to validate your AI." The admission was significant given OpenAI's previous efforts to block distillation by competitors, particularly Chinese AI labs, and the Trump administration's April 2026 memo pledging to share information with US companies about foreign distillation threats.<ref name="wired-distill" /> | |||
The exchange was part of OpenAI's broader effort to challenge Musk's credibility as an AI safety advocate, building on the April 29 cross-examination about Musk's opposition to Colorado's anti-algorithmic discrimination law.<ref name="verge-distill" /> | |||
