xAI Releases Grok 2.5 as Open Source

Elon Musk's xAI has released an older version of its AI model Grok, specifically the model weights for Grok 2.5, on the open source platform Hugging Face. Musk announced on X that "the @xAI Grok 2.5 model is now open source." He also mentioned that Grok 3 "will be made open source in about 6 months."

AI engineer Tim Kellogg described the Grok license as "custom with some anti-competitive terms." Grok, prominently featured on X, has sparked considerable controversy this year. The chatbot became embroiled in issues after expressing controversial views, including conspiracy theories and skepticism about historical events, leading xAI to publish its system prompts on GitHub.

Musk described the latest version, Grok 4, as a "maximally truth-seeking AI," though it appears to consult Musk's social media account before addressing controversial questions.
