Magistral Small — Mistral AI 的本地 AI 模型

作者: Jakub Rusinowski · 最后更新:

Mistral's reasoning line: Mistral Small with long chain-of-thought added via SFT on Magistral Medium traces plus RL. Apache 2.0, vision-capable, and sized so the whole thing fits a single RTX 4090 or a 32 GB MacBook once quantized — which is the point. Reasoning traces degrade past roughly 40K tokens even though the context window runs to 128K.

变体

Magistral Small 最小的变体在 Q4_K_M 下约需 15 GB 显存——量化权重加框架开销,不含 KV 缓存。

我的 GPU 能运行 Magistral Small 吗?

Magistral Small — 常见问题

How much VRAM does Magistral Small need?

Magistral Small needs about 15 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Magistral Small 24B (15 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.

Can I run Magistral Small on an RTX 4090 (24 GB)?

Yes — Magistral Small runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.

What quantization should I use for Magistral Small?

Q4_K_M is the best balance of quality and VRAM for Magistral Small in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.

How do I run Magistral Small with Ollama?

Install Ollama, then run: ollama run magistral:24b. This downloads Magistral Small and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
