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

Elon Musk testified in court that his AI startup xAI used OpenAI's models to train its own AI system called Grok through model distillation (a technique where a larger AI model teaches a smaller one by transferring knowledge). Model distillation is a common practice in the AI industry, though it can be used legitimately within a single company or potentially misused by competitors trying to copy a rival's AI performance.
