Mistral publishes the weights of its trillion-parameter Large 4 model

Mistral, the French AI company, has released the full weights of Mistral Large 4. The model has about one trillion parameters. Anyone can now download it and run it on their own hardware. Mistral says it is the strongest open model for coding and for security work such as finding and fixing vulnerabilities.

The weights are on Hugging Face under a modified MIT licence. Use, fine-tuning and commercial use are allowed. Companies that want to sell the model as a hosted cloud service need a separate licence. The release follows a preview earlier in October, and Mistral says three more weeks of training lifted its terminal benchmark score from 28 to 41 percent. The benchmark claims are the vendor's own. For teams that need to keep data in house, it widens the choice of large models they can host themselves.
