Cheaper, Better, Faster, Stronger

Mixtral 8x22B is our latest open model. It sets a new standard for performance and efficiency within the AI community. It is a sparse Mixture-of-Experts (SMoE) model that uses only 39B active parameters out of 141B, offering unparalleled cost efficiency for its size.

Mixtral 8x22B comes with the following strengths:

It is fluent in English, French, Italian, German, and Spanish
It has strong mathematics and coding capabilities
It is natively capable of function calling; along with the constrained output mode implemented on la Plateforme, this enables application development and tech stack modernisation at scale
Its 64K tokens context window allows precise information recall from large documents

Truly open

We believe in the power of openness and broad distribution to promote innovation and collaboration in AI.

We are, therefore, releasing Mixtral 8x22B under Apache 2.0, the most permissive open-source licence, allowing anyone to use the model anywhere without restrictions.

Efficiency at its finest

We build models that offer unmatched cost efficiency for their respective sizes, delivering the best performance-to-cost ratio within models provided by the community.

Mixtral 8x22B is a natural continuation of our open model family. Its sparse activation patterns make it faster than any dense 70B model, while being more capable than any other open-weight model (distributed under permissive or restrictive licenses). The base model's availability makes it an excellent basis for fine-tuning use cases.
