xAI makes Grok 2.5 open source
"xAI, Elon Musk's AI company, has released the Grok 2.5 model as open source. The model is available via the Hugging Face platform and can be downloaded and run locally by developers and researchers. The Grok 2.5 model was trained and used by xAI in 2024 and is now being made available as a community release. The package consists of 42 files with a total size of approximately 500 GB."
"The weights of Grok 2.5 are covered by the Grok 2 Community License Agreement. This license allows the model to be used and modified freely, but explicitly prohibits its use for training, creating, or improving other AI models. With this, xAI has opted for a hybrid approach: the code and weights are openly available, but their use remains restricted under certain conditions."
"This is not the first time xAI has publicly released a model. In March 2024, the company also made the raw base model of Grok-1 available. This was done without any specific fine-tuning. This positions xAI as the opposite of OpenAI, which only shares limited and less powerful variants of its ChatGPT models with researchers and companies. Musk positions Grok as an accessible alternative, although the model does require considerable computing power."
xAI released Grok 2.5 as open-source via Hugging Face, offering a roughly 500 GB package across 42 files that developers and researchers can download and run locally. Full deployment requires eight GPUs with at least 40 GB of memory each and the SGLang inference engine to run an inference server for chat applications. The Grok 2 Community License allows use and modification but explicitly forbids using the weights to train, create, or improve other AI models. xAI previously released the raw Grok-1 base model in March 2024 and positions Grok as a more accessible alternative to OpenAI. The model has faced stability and reliability issues, including offensive outputs tied to outdated code that was removed.
