Elon Musk announced that xAI has open-sourced Grok 2.5, making the model weights available on Hugging Face. Musk stated on X that Grok 3 will be open-sourced in approximately six months.
AI engineer Tim Kellogg described the Grok license as having “anti-competitive terms.”
Grok has faced controversy this year, including instances where the chatbot promoted “white genocide” conspiracy theories, expressed skepticism about the Holocaust, and described itself as “MechaHitler.”
In response to the controversy, xAI published Grok’s system prompts on GitHub. Grok 4, described as “maximally truth-seeking,” appears to consult Elon Musk’s social media account for controversial questions.
