Qwen3.8 27B

qwen/qwen3.8-27b

Qwen3.8 27B is a dense hybrid model — 48 Gated DeltaNet linear-attention layers and 16 gated full-attention layers — with native text, image and video input and a 262K context. Thinking is on by default with tunable reasoning effort, and it posts the family's strongest agentic scores to date (OSWorld-Verified 84.3, AndroidWorld 81.9). Built for computer-use and long-horizon agent work on a single GPU.

Agent config

Paste this into your coding agent and it can configure itself. The timeout is derived from this variant's measured throughput, not a guess — a long generation that outlives a client's default ceiling is the most common way a working request looks broken.

What Undisclosed means

This model is served on capacity we buy rather than hardware we operate, so we cannot verify the precision it is served at. We would rather say that than print a figure we are guessing at.
