Ministral 3 8B

by Mistral

Mistral's efficient 8 billion parameter model combines text and vision understanding with support for function calling and structured outputs, backed by a 256k token context window. Released December 2025, Ministral 3 8B is built for edge and local deployment while maintaining strong performance across reasoning, commonsense understanding, and instruction following. Designed specifically for on-device and edge scenarios, the model pairs an 8.4B language model with a 0.4B vision encoder. Unlike its predecessor, Ministral 3 8B adds vision understanding, making it a multimodal edge solution that supports dozens of languages including English, French, Spanish, German, Italian, Portuguese, Dutch, Chinese, Japanese, Korean, and Arabic.
