Devstral Small 2 · 24B

A December 2025 coding model for explaining code, suggesting changes, and interpreting screenshots.

  • 4 min read
  • ~32 GB RAM to start
  • 15 GB download

A coding-focused local model that can work with text and images. In desktop chat, paste the relevant code and error rather than expecting automatic repository access.

Where it works well

  • Software engineering tasks.
  • Code explanations and proposed edits.
  • Image inputs alongside code context.

Common use cases

  • Explain an error with its surrounding code.
  • Suggest a focused refactor.
  • Translate a UI screenshot into implementation notes.

Know its limits

  • Repository editing needs a compatible coding tool; desktop chat cannot edit your files by itself.
  • Test generated code and check dependency APIs.

Run it on your computer

Start with a compressed download and a short conversation. Our estimate is about 32 GB of total RAM or Mac unified memory, with room for the operating system. The listed 15 GB download is the model file, not its full running memory use.

Check the model’s supported runtime and hardware before loading it. System RAM on a PC and unified memory on a Mac are different from dedicated NVIDIA VRAM. A memory match doesn’t guarantee compatibility or speed. Choose a smaller model if responses are too slow.

Use a desktop app that supports the listed model format, such as LM Studio or Ollama. Download the exact local variant, load it in Chat, and start with one small task. Model downloads need internet; local chat can work offline once the model is downloaded.
