Devstral-2 123B — 显存、速度与本地部署

作者: Jakub Rusinowski · 最后更新:

The flagship coding agent, and dense — Mistral deliberately did not build this one sparse, so all 123B stream per token and throughput scales accordingly. Scores 71.6% on SWE-bench Verified, the best open-source coding-agent result at release. Requires about 75 GB at Q4_K_M, so a dual-GPU workstation. Apache 2.0.

Devstral-2 123B 在 Q4_K_M 下约需 75 GB 显存——量化权重加框架开销,不含 KV 缓存。在 Apple Silicon 上,这部分来自统一内存。

我的 GPU 能运行 Devstral-2 123B 吗?

Devstral 的其他尺寸

Devstral-2 123B — 常见问题

How much VRAM does Devstral-2 123B need?

About 75 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.

Does Devstral-2 123B run on an RTX 4090 (24 GB)?

No. Devstral-2 123B needs about 75 GB at Q4_K_M, more than a single RTX 4090's 24 GB. It needs a larger card, several GPUs, or Apple Silicon with enough unified memory — or it runs with part of the weights offloaded to system RAM, which is much slower.

How do I run Devstral-2 123B locally?

Install Ollama and run `ollama run devstral:123b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.

What other sizes does Devstral come in?

Devstral-2 123B (75 GB), Devstral 2 22B (14 GB), Devstral Small 2505 24B (15 GB), Devstral Small 2 24B (15 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
