The weights are released under the Modified MIT License. Commercial use is allowed with conditions. Companies with global consolidated monthly revenue above US$20 million need a separate commercial license from Mistral AI.
The official weights on Hugging Face take about 128 GB in FP8. Running the model needs at least that much memory across GPUs and system RAM, plus room for the context cache; quantized versions need less.
