Overview
Qwen3.8-27B is the compact member of Alibaba's Qwen3.8 open-model series. It's a dense model with 27B parameters, built on the Qwen3.5 architecture.
Qwen aims it at coding, professional work, research and long multi-step agent tasks, and describes it as easy to deploy. Its vision support covers documents, diagrams and long videos.
The id comes from live GET https://api.luv13.ai/v1/models; every other fact comes from the maker's sources below. The context window is the maker's published figure, not a luv13 limit; luv13 hasn't published its own per-model limits.
Qwen writes the name as Qwen3.8-27B; luv13 lists it as Qwen 3.8 27B.
