Musk Open-Sources Grok 2.5: Chinese Companies Are xAI’s Biggest Rivals

Musk announced that xAI has open-sourced Grok 2.5, and Grok 3 will also be open-sourced in six months. Grok 2.5 is available for download on HuggingFace, consisting of 42 files with a total size of about 500GB, and requires eight GPUs with more than 40GB of memory each to run. The model previously outperformed Claude and GPT-4 on the LMSYS leaderboard, demonstrating strong performance across multiple domains. The open-source license is relatively strict, allowing only non-commercial use.
