Yesterday, Elon Musk took the stand in federal court.

Under oath. In front of a judge. In his own lawsuit against OpenAI.
And he admitted xAI used OpenAI’s models to train Grok.
Read that again.
The man suing OpenAI for billions — claiming they betrayed their nonprofit mission and stole the future of AI — just confessed that his own company used their tech to build Grok, the chatbot now sitting inside every Tesla.
His defense? “Everyone does it.” 🧠
This practice is called distillation. You take a powerful AI model, ask it millions of questions, and use its answers to train your own cheaper version. It’s how DeepSeek shocked the world. It’s what OpenAI, Google, and Anthropic are scrambling to block.
And now Musk has admitted xAI did it too.
Let that sink in:
→ He sues OpenAI for going for-profit.
→ He builds a for-profit competitor.
→ He trains that competitor on OpenAI’s models.
→ Then tells a federal judge it’s “standard practice.” ⚡
The plaintiff just became the strongest witness for the defense.
This trial isn’t really about Musk vs. Altman anymore. It’s about the question nobody in Silicon Valley wants answered:
Who actually owns the intelligence coming out of these labs — the companies that built it, or anyone clever enough to copy it?
Whatever the jury decides, the AI industry will never look the same.
