With 22 billion parameters and training across more than 80 programming languages, including Python, Java, C, C++, JavaScript, Bash, Swift, and Fortran, Mistral Codestral covers the breadth of languages developers encounter in production. Mistral Codestral's defining technical feature is fill-in-the-middle (FIM) support. Unlike instruction-only models that generate code from a prompt, FIM lets Mistral Codestral complete code within a partial snippet. Mistral Codestral can insert a function body, finish a conditional branch, or complete a class method given the surrounding context. This makes Mistral Codestral a natural fit for IDE integrations like Continue.dev and Tabnine, where code above and below the cursor is provided as context. Beyond completion, Mistral Codestral handles test generation and documentation authoring. Its context window of 128K tokens was over four times larger than those of competing models at launch, so Mistral Codestral can process full files rather than truncated snippets. ## [Copy link to heading](#what-to-consider-when-choosing-a-provider)What To Consider When Choosing a Provider - Configuration: Mistral Codestral's context window of 128K tokens was over four times larger than the 4K to 16K windows typical of competing code models at release. You can reason over entire files or multi-file snippets in a single request. - Zero Data Retention: Zero Data Retention is available for this model. It is offered on a per-provider and model basis. See the [documentation](https://vercel.com/docs/ai-gateway/security-and-compliance/zdr) for details. - Authentication: AI Gateway authenticates requests using an [API key](https://vercel.com/docs/ai-gateway/authentication-and-byok#api-key-authentication) or [OIDC token](https://vercel.com/docs/ai-gateway/authentication-and-byok#oidc-token-authentication). You do not need to manage provider credentials directly. ## [Copy link to heading](#when-to-use-mistral-codestral)When to Use Mistral Codestral ### Best for - IDE and editor plugins: Requiring fill-in-the-middle code completion - Automated test generation: Producing unit or integration tests from existing source code - Documentation generation: Writing inline docs and reference material for functions, classes, and modules - Code translation between languages: Converting source across languages, for example Python to TypeScript - Broad language coverage: Applications that need wide support in a single model ### Consider alternatives when - Agentic software engineering: You need multi-file orchestration (consider Devstral) - Semantic code search: Your primary requirement is search rather than generation (consider Codestral Embed) - Reasoning-heavy problem solving: You need deep reasoning alongside coding (consider Magistral) ## [Copy link to heading](#conclusion)Conclusion Mistral Codestral established Mistral's footprint in developer tooling when it launched. Mistral Codestral remains relevant for teams that need broad language coverage, fill-in-the-middle completion, and a context window of 128K tokens optimized for code. Mistral's coding model family builds on this foundation.
