Qwen3.8 — Alibaba Cloud 的本地 AI 模型

作者: Jakub Rusinowski · 最后更新:

Alibaba's August 2026 wave. The 27B is a natively multimodal dense model under Apache 2.0 with a 262K context that extends to 1M via YaRN — small enough for one consumer card, which is the combination most of this site's visitors are looking for. Qwen3.8-Max sits at the other extreme: 2.4T parameters with roughly 95B active, open-weighted under its own licence. Qwen3.8-Flash-Next is neither — an experimental preview of the Qwen4 architecture, 180B resident but only 6B active, under the Qwen Community License rather than Apache.

变体

Qwen3.8 最小的变体在 Q4_K_M 下约需 18 GB 显存——量化权重加框架开销,不含 KV 缓存。

我的 GPU 能运行 Qwen3.8 吗?

Qwen3.8 — 常见问题

How much VRAM does Qwen3.8 need?

Qwen3.8 needs about 18 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Qwen3.8 27B (18 GB, Q4_K_M); Qwen3.8-Max (1450 GB, Q4_K_M); Qwen3.8-Flash-Next (109 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.

Can I run Qwen3.8 on an RTX 4090 (24 GB)?

Yes — Qwen3.8 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 Qwen3.8?

Q4_K_M is the best balance of quality and VRAM for Qwen3.8 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 Qwen3.8 with Ollama?

Install Ollama, then run: ollama run qwen3.8:27b. This downloads Qwen3.8 and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
