Can I run devstral?
Devstral: the best open source model for coding agents
Parameter counts and memory belong to each build below. A family can contain several sizes and tasks; fitting in memory is not a quality ranking.

Showing the 3 smallest non-alias builds. Choose any build and change the context. A context above the build's documented maximum is a hypothetical calculation, not a supported setting.
How to run devstral locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Download this exact build in a terminal:
ollama pull devstral:24b - 3.Check the source for the build's task. For text generation, run
ollama run devstral:24b. Base/text builds may need a prompt template; an instruct build is usually the appropriate starting point for a conversation.
Frequently asked questions about devstral
- How much VRAM do I need to run devstral?
- At 4K context, the smallest published build of devstral (Q4_K_M) needs roughly 15.4 GB of GPU memory once weights, KV cache, compute buffers and runtime overhead are counted. Bigger quantizations and longer context windows need more. It can also run partly or entirely on the CPU using system RAM, more slowly.
- Can I run devstral without a dedicated GPU?
- A supported CPU runtime can use system RAM. The smallest listed build needs an estimated 15.4 GB at 4K context, plus headroom for your operating system. Check the build's runtime requirements. We have not measured its speed on your CPU.
- How big is the devstral download?
- The smallest published build is 13.3 GB. There are 3 builds in total, the largest being 43.9 GB. Leave some extra free disk space beyond the download itself.
- How do I run devstral locally?
- Install Ollama, then download a specific build with "ollama pull devstral:24b". For a build that supports text generation, use ollama run with the same tag. Check the model source for its task and prompt format.
