Mistral Large 3 675B-A41B — 显存、速度与本地部署
作者： Jakub Rusinowski · 最后更新：
PREVIEW — unverified. ~675B-total MoE with ~41B active per token, multimodal, Apache 2.0, 256K context. At Q4 it needs ~400 GB — an 8×80 GB server or equivalent. Apache 2.0 would make it one of the most permissive frontier-scale open weights if confirmed. Verify against the Hugging Face model card.
Mistral Large 3 675B-A41B 在 Q4_K_M 下约需 408 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。
按量化级别的显存与速度
计算基准：NVIDIA RTX 4090 (24 GB)。仅含权重与开销：该模型架构未公开，因此未计入 KV 缓存。

Mistral Large 3 675B-A41B — 常见问题
How much VRAM does Mistral Large 3 675B-A41B need?
About 408 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 Mistral Large 3 675B-A41B run on an RTX 4090 (24 GB)?
No. Mistral Large 3 675B-A41B needs about 408 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 Mistral Large 3 675B-A41B locally?
Install Ollama and run `ollama run mistral-large-3`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
