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.

The cheapest GPU that runs Qwen3.8 locally (min 18 GB VRAM) is the AMD Radeon RX 7900 XT (20 GB).
Install Ollama then run: ollama run qwen3.8:27b
Minimum VRAM: 18 GB. For best results use Q4_K_M quantization.
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.
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.
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.
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.
