Ministral 8B

by Mistral

Mistral's efficient 8 billion parameter model delivers solid reasoning, world knowledge, and function-calling capabilities with a 128k token context window. Built for rapid inference and low memory overhead, Ministral 8B serves developers seeking a lightweight alternative to larger models while maintaining language understanding and instruction following. The model is succeeded by Ministral 3 8B (released December 2025), which expands context to 256k tokens, adds vision, and supports structured output. For new deployments, Ministral 3 8B is the recommended option.
