Qwen 3.5 Medium

The medium tier of Qwen 3.5 is Alibaba's flagship open lineup, offering both dense and mixture-of-experts models that punch well above their parameter counts on coding, math, and vision benchmarks.

From a 27B dense model to a 397B MoE, the range scales from single-GPU setups to multi-GPU servers, all natively multimodal and with switchable reasoning modes.
