About Qwen3.8-27B

Qwen3.8-27B is the compact member of Alibaba’s Qwen3.8 generation — 27 billion parameters, dense, open under Apache 2.0 — and it punches well above its size. Alibaba reports 61.7% on SWE-bench Pro, above its own figure for Claude Opus 4.6, plus 89.2% on GPQA Diamond and 84.3% on the OSWorld computer-use test.

It reads images and video as well as text, holds 262K tokens natively, and thinks by default with adjustable effort. Its design mixes fast linear-attention layers with full attention, which keeps long inputs cheap to process.

Where to be careful

Every headline score is Alibaba’s own.

Stretching it to a million tokens can hurt quality on shorter texts.
