Elon Musk confirms xAI used OpenAI’s models to train Grok

Elon Musk testified in a California federal court that his AI startup, xAI, used OpenAI's models through a process called model distillation to train its own AI, Grok. The practice, common in the industry, involves a larger 'teacher' model transferring knowledge to a smaller 'student' model, though it can raise legal and ethical concerns.
