Mistral, a French AI startup backed by Microsoft, has unveiled Codestral, a generative AI model designed to assist developers in generating and interacting with code across over 80 programming languages. This powerful new tool offers a range of capabilities, from completing coding functions and writing tests to answering questions about codebases in natural language.
Codestral Key Features
- Codestral boasts an impressive training dataset encompassing over 80 programming languages, including popular ones like Python, Java, C++, and JavaScript, as well as specialized languages such as Swift and Fortran.
- The model excels at completing coding functions, writing tests, and finishing partial code using a fill-in-the-middle mechanism. It can also answer questions about a codebase in English, making it a versatile tool for developers.
- Mistral has integrated Codestral into its Le Chat conversational AI platform and offers a paid API for access. The model is also designed to work with various app frameworks and development environments, such as LlamaIndex, LangChain, Continue.dev, and Tabnine.

Licensing Restrictions
Despite being described as "open," Codestral's license imposes significant restrictions on its usage. The license prohibits the use of Codestral and its outputs for any commercial activities, with only a limited allowance for "development" purposes. Even this development exception comes with caveats, explicitly banning internal usage by employees in the context of a company's business activities. These licensing limitations may stem from the fact that Codestral was likely trained on copyrighted content, although Mistral has not confirmed or denied this speculation.

Performance and Practicality
At 22 billion parameters, Codestral is a computationally intensive model that requires substantial resources to run effectively. While it demonstrates competitive performance on certain benchmarks, it does not represent a significant leap over existing models in terms of capabilities. The practical application of Codestral may be limited by its licensing restrictions and the considerable computational power needed for optimal performance.

Market Strategy and Challenges
Mistral is positioning itself as a flexible alternative to major AI models from tech giants like OpenAI and Google, aiming to capitalize on the growing demand for customizable AI solutions. The startup is expanding its presence in the U.S. market, recently hiring Marjorie Janiewicz as its first U.S. general manager, and seeking a $6 billion valuation. However, the adoption of generative AI tools like Codestral comes with challenges, as studies have shown that such tools can introduce errors and security issues into codebases. Despite these concerns, the demand for efficient and accurate code generation tools continues to grow.
