What is Mistral Codestral 2501?
Codestral 25.01 is Mistral AI’s upgraded code-generation model, released January 13, 2025. Featuring a more efficient architecture and improved tokenizer, it delivers code completion and intelligence about 2× faster than its predecessor, with support for fill-in-the-middle (FIM), code correction, test generation, and proficiency in over 80 programming languages, all within a 256K-token context window.
Who can use Mistral Codestral 2501 & how?
  • Developers & Engineers: Ideal for autocomplete in IDEs, generating snippets, tests, and FIM tasks in real time.
  • Technical Teams: Accelerate code reviews, bug fixes, and multi-language code generation.
  • Researchers & Benchmarkers: Evaluate state-of-the-art code LLMs in FIM tasks and speed benchmarks.
  • Enterprise DevOps: Deploy locally or in VPCs for secure, scalable code generation workflows.
  • Starter to Advanced Programmers: Use via Continue IDE plugins for VS Code or JetBrains to boost productivity instantly.

How to Use Codestral 25.01?
  • API Access: Available globally via Mistral’s “`codestral-2501`” endpoint on multiple platforms.
  • Integrate in IDEs: Select Codestral 25.01 in Continue plugin for VS Code/JetBrains for real-time code assistance.
  • Utilize FIM Mode: Use fill-in-the-middle prompts for snippet completion or test generation within existing code.
  • Leverage Long Context: Handle entire repositories or large files with 256K tokens context.
  • Self-Host: Support for local or private deployment to meet enterprise security and residency requirements.
What's so unique or special about Mistral Codestral 2501?
  • Twice the Speed: About 2× faster code generation than Codestral 24.05, thanks to architectural improvements.
  • FIM Benchmark Leader: Clear #1 on FIM tasks, with 95.3% average pass@1 across Python, Java, and JS.
  • Wide Language Support: Proficient in 80+ languages including Python, SQL, C++, JS, Bash, TypeScript, C#, Swift, and Fortran.
  • Huge Context Capability: 256K-token window supports large codebases or multi-file contexts seamlessly.
