xAI open sources base model of Grok, but without any training code

Elon Musk’s xAI has open sourced the base code of Grok AI model, but without any training code. The company described it as the 314 billion parameter Mixture-of-Expert model on GitHub.

In a blog post, xAI said that the model wasn’t tuned for any particular application such as using it for conversations. The company noted that Grok-1 was trained on a “custom” stack without specifying details. The model is licensed under Apache License 2.0, which permits commercial use cases.

Last week, Musk noted on X that xAI intended to open source the Grok model this week. The company released Grok in a chatbot form last year, accessible to Premium+ users of X social network. Notably, the chatbot could access some of the X data, but the open source model doesn’t include connections to the social network.

Many notable companies have open sourced some of their AI models including Meta’s LLaMa, Mistral, Falcon, and AI2. In February, Google also released two new open models called Gemma2B and Gemma7B.

Some AI-powered tool makers are already talking about using Grok in their solutions. Perplexity CEO Aravind Srinivas posted on X that the company will fine-tune Grok for conversational search and make it available to Pro users.

Musk has been in a legal battle with OpenAI and sued the company earlier this month over the “betrayal” of the nonprofit AI goal. Since then, he has called out OpenAI and Sam Altman on X multiple times.
