Qwen3.8-Max — 显存、速度与本地部署

作者: Jakub Rusinowski · 最后更新:

2.4 trillion parameters with roughly 95B active per token. Shipped as a service on 3 August 2026 with open weights following on 12 August under a model-specific Qwen3.8-Max licence, not Apache. Cluster-class self-hosting — about 1.45 TB at Q4_K_M — so for almost everyone this is an API model; it is listed here so the hardware checker can say so rather than stay silent.

Qwen3.8-Max 在 Q4_K_M 下约需 1450 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。

运行 Qwen3.8-Max

Qwen3.8-Max is not practical on a single consumer GPU: it needs about 1449.8 GB at Q4_K_M, more than any single device in our catalogue holds with headroom. How multi-GPU inference works, or rent a multi-GPU server by the hour:

Qwen3.8 的其他尺寸

Qwen3.8-Max — 常见问题

How much VRAM does Qwen3.8-Max need?

About 1450 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 Qwen3.8-Max run on an RTX 4090 (24 GB)?

No. Qwen3.8-Max needs about 1450 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 Qwen3.8-Max locally?

Install Ollama and run `ollama run qwen3-8`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.

What other sizes does Qwen3.8 come in?

Qwen3.8 27B (18 GB), Qwen3.8-Max (1450 GB), Qwen3.8-Flash-Next (109 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
