Elon Musk says xAI trained Grok using OpenAI models sparking fresh AI model copyright questions

Testimony points to distillation, not just imitation

Elon Musk testified that xAI trained Grok using OpenAI models, drawing attention to “distillation,” the method used to transfer capabilities into smaller systems. The claim intensifies scrutiny of how frontier AI labs protect their models while challengers argue they can learn from outputs. Legal and technical debates over copying, licensing, and competitive fairness are likely to intensify.
