MathΣtral | Mistral AI

Mistral AI launched Mathstral, an instruction-tuned 7B model built for advanced math and STEM reasoning.

Developed with Project Numina, the model was released to the science community with open weights on HuggingFace.

Mathstral shows strong benchmark results on tests like MATH and MMLU, with further gains from extra inference-time compute, majority voting, or reward-model selection.

The release gives researchers and developers a specialized open model for harder reasoning tasks without needing a larger general-purpose system.
