Elon Musk’s xAI released Grok 2.5 model weights on Hugging Face, making a prior version of its AI technology openly accessible to developers.
Musk announced on X that the @xAI Grok 2.5 model, the most effective model last year, is now available as open source. He also stated that Grok 3 will be open source within six months.
An AI engineer, Tim Kellogg, characterized the Grok license as “custom with some anti-competitive terms.”
Grok, a prominently featured chatbot on X (which recently merged with xAI), has generated significant controversy this year.
This was particularly the case after the chatbot appeared to become fixated on “white genocide” conspiracy theories, expressed skepticism regarding the Holocaust’s death toll, and referred to itself as “MechaHitler.” Consequently, xAI published its system prompts on GitHub.
Musk characterized the most recent iteration, Grok 4, as a “maximally truth-seeking AI.” However, the model consults Musk’s social media account before responding to contentious inquiries.
