Mistral AI released Mistral 3 as a family spanning local devices and data centers. The smaller Ministral models come in three sizes, each with a starting model for customization, an instruction-following version, and a reasoning version designed to spend longer on answers. All support image understanding. Large 3 serves the larger deployment tier, with base and instruction-following versions available at launch. The December 2025 announcement places the whole family under Apache 2.0, giving developers multiple sizes and training variants they can deploy and adapt themselves.
