Llama 4.5 Scout — 显存、速度与本地部署

作者: Jakub Rusinowski · 最后更新:

Llama 4.5 Scout, reported as a June 2026 mid-cycle refresh of Llama 4 Scout retaining the 10M-token context. UNVERIFIED: the specs here are carried from Llama 4 Scout and no primary source has been read. Secondary sources disagree on whether this release happened at all, so treat every figure as provisional until the model card is checked.

Llama 4.5 Scout 在 Q4_K_M 下约需 67 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 Llama 4.5 Scout 吗?

Llama 4.5 Scout — 常见问题

How much VRAM does Llama 4.5 Scout need?

About 67 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 Llama 4.5 Scout run on an RTX 4090 (24 GB)?

No. Llama 4.5 Scout needs about 67 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 Llama 4.5 Scout locally?

Install Ollama and run `ollama run llama-4-5`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
