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.
Announced in November, Grok is an AI assistant similar to ChatGPT that is available to X Premium+ subscribers who pay $16 a month to the social media platform formerly known as Twitter. At its heart is a mixture-of-experts LLM called “Grok-1,” clocking in at 314 billion parameters. As a reference, GPT-3 included 175 billion parameters. Parameter count is a rough measure of an AI model’s complexity, reflecting its potential for generating more useful responses.
