Codestral 2508

Codestral 2508 is Mistral's language model specialized for code generation, completion, and manipulation tasks, released in August 2025 with a 256K token context window.

Strengths

It handles fill-in-the-middle code completion, performs well on code generation across multiple programming languages, and supports reasoning about code structure and intent.

Best for

Workflows involving code generation, refactoring, debugging, and code review where a model tuned specifically for programming tasks is needed.

Limitations

It is specialized for code rather than general-purpose reasoning, so it may underperform on non-coding tasks compared to general language models in Mistral's lineup.
