- 2.Run this in a terminal:
ollama run devstral-2:123b - 3.The weights download on first run, then an interactive prompt opens.
Frequently asked questions about devstral-2
- How much VRAM do I need to run devstral-2?
- At 4K context, the smallest published build of devstral-2 (Q4_K_M) needs roughly 100.1 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-2 without a dedicated GPU?
- Yes, but slowly. Without a GPU the model runs on the CPU using system RAM, which usually means a few tokens per second rather than dozens. You would need at least 100.1 GB of free RAM for the smallest build.
- How big is the devstral-2 download?
- The smallest published build is 69.8 GB. There are 3 builds in total, the largest being 232.9 GB. Leave some extra free disk space beyond the download itself.
- How do I run devstral-2 locally?
- Install Ollama, then run "ollama run devstral-2:123b" in a terminal. The weights download on first use and an interactive session opens.
