Overview

• xAI uploaded Grok 2.5's source code to Hugging Face, allowing anyone to download, run, and modify the model locally.
• xAI’s license bars using Grok to train, create, or improve other AI models, curbing common forms of reuse.
• Musk said the newer Grok 3 will be made open source in about six months, a timeline observers note could slip.
• The move continues xAI’s practice of releasing older Grok versions publicly, contrasting with OpenAI’s more limited openings.
• xAI previously released the raw Grok‑1 base model in March 2024 and says it has addressed past antisemitic outputs blamed on deprecated code.
