Tencent uploaded UI-Mate-27B and UI-Mate-9B to Hugging Face (Apache-2.0, built on Qwen3.6-27B and a 9B backbone, supervised-fine-tuned with online RL): they observe live screenshots and emit structured pyautogui-compatible keyboard and mouse actions. UI-Mate-27B scores OSWorld-Verified 77.0, WindowsAgentArena 66.2, and OSWorkerBench strict 41.00 / progress 76.86; one-shot demonstration guidance alone doubles OSWorkerBench-Subset strict success (17.17 to 35.35) and lifts OSWorld-Subset progress 40.27 to 65.75.

Why it matters

One of the strongest open GUI-agent weights released in 2026; the demonstration guidance lever gives a concrete handle for desktop-automation research and tooling on top of a permissive Apache-2.0 checkpoint.

Importance: 3/5
