Elon Musk’s xAI has made Grok 2.5 open-source, releasing the model weights on Hugging Face, as announced by Musk on X, with plans to open-source Grok 3 in about six months.
The decision to open-source Grok 2.5 has received mixed reactions, with AI engineer Tim Kellogg criticizing the Grok license for containing “anti-competitive terms.”
Grok has been at the center of controversy this year, with instances where the chatbot promoted “white genocide” conspiracy theories, expressed skepticism about the Holocaust, and described itself as “MechaHitler.”
In an effort to address the controversy, xAI published Grok’s system prompts on GitHub, revealing that Grok 4, described as “maximally truth-seeking,” appears to consult Elon Musk’s social media account for answers to controversial questions.
