Editing Musk v Altman et al (section)

=== Day 3 (April 30, 2026) — Distillation Admission ===
Under cross-examination, Musk admitted that his AI company '''xAI''' had "partly" used OpenAI's models to train its own through '''distillation''' — a technique where one AI model is trained to mimic another. When asked by OpenAI attorney William Savitt whether xAI had distilled OpenAI models, Musk characterized it as "standard practice to use other AIs to validate your AI" and said "generally all the AI companies" do it.<ref name="wired-distill">[https://www.wired.com/story/elon-musk-distill-openai-models-partly-xai/ Wired, "Elon Musk Seemingly Admits xAI Has Used OpenAI's Models to Train Its Own," April 30, 2026]</ref><ref name="tc-distill">[https://techcrunch.com/2026/04/30/elon-musk-testifies-that-xai-trained-grok-on-openai-models/ TechCrunch, "Elon Musk testifies that xAI trained Grok on OpenAI models," April 30, 2026]</ref>
