Elon Musk testifies that xAI trained Grok on OpenAI models

# Elon Musk Says xAI Copied OpenAI's Technology to Build Grok Elon Musk acknowledged in testimony that his AI company xAI trained its Grok chatbot using technology from OpenAI's models rather than building it entirely from scratch. This practice, called "distillation," is increasingly common among AI companies trying to compete affordably with tech giants, but it's raising legal concerns about whether smaller players are essentially copying the work of larger rivals. The issue highlights a brewing battle over who owns AI technology and whether smaller companies can legally use bigger competitors' models to jumpstart their own products.
