On Sunday, Elon Musk's AI firm xAI released the base model weights and network architecture of Grok-1, a large language model designed to compete with the models that power OpenAI's ChatGPT. The open-weights release through GitHub and BitTorrent comes as Musk continues to criticize (and sue) rival OpenAI for not releasing its AI models in an open way.
