Key point
Mistral AI has released Codestral, a 22B-scale open-weight code generation model supporting over 80 programming languages.
Details
Mistral AI has unveiled Codestral, its first code-specific model. Codestral is a 22B-scale open-weight generative AI model specialized for code generation tasks.
The model supports over 80 programming languages, ranging from popular languages like Python, Java, C, C++, JavaScript, and Bash to more specialized ones such as Swift and Fortran. Developers can use it to perform tasks such as:
- Completing code functions and writing partial code
- Writing test code
- Completing code via the Fill-in-the-middle (FIM) mechanism
Codestral offers an optimal balance between performance and latency, and notably supports a wide context window of 32k. This outperforms competing models (4k–16k) and has demonstrated excellent results on the RepoBench benchmark, which requires long-term dependencies.
Codestral is currently available for download via HuggingFace, under the Mistral AI Non-Production License, which permits use for research and testing purposes. It is also available through a dedicated endpoint (codestral.mistral.ai).
