Elon Musk Testifies xAI Partly Distilled OpenAI Models to Train Grok
On 30 April 2026, Elon Musk told a California federal court that xAI used model distillation of OpenAI systems to help build its Grok chatbot— the first on-record admission by a major U.S. competitor of tapping a rival’s proprietary AI outputs.
Focusing Facts
- While under oath on 30 Apr 2026, Musk answered that xAI had "partly" distilled OpenAI models, calling it “standard practice” across the industry.
- OpenAI’s published terms forbid using its outputs for training competing models, making Musk’s statement a de-facto acknowledgment of a policy breach.
- The revelation lands eight days after an 23 Apr 2026 White House memo that accused Chinese actors of large-scale distillation attacks on U.S. AI labs.
