Mistral AI released Mistral 3, a family of open-weight models (the model files anyone can download) under the permissive Apache 2.0 licence. Mistral Large 3 has 675 billion parameters (the numbers a model learns in training), but as a sparse mixture-of-experts model it uses only 41 billion of them at a time; it was trained on 3,000 NVIDIA H200 GPUs. The smaller Ministral 3 models come in 3 billion, 8 billion and 14 billion parameter sizes for use on local and edge devices.
