UI-Mate-9B is an open-weight foundation GUI agent for long-horizon work across applications and operating systems. It observes live screenshots, reasons over the visible state, and produces structured keyboard and mouse actions for native desktop interaction. The model is trained with supervised fine-tuning followed by online reinforcement learning in executable GUI environments. It is released under the Apache License 2.0.
UI-Mate-9B is a 9B-parameter model based on Qwen3.5-9B, fine-tuned for GUI agent tasks. It takes task instructions, screenshots, and interaction history as input, and outputs reasoning, action descriptions, and structured computer-use tool calls. The action space includes mouse, keyboard, scrolling, waiting, user interaction, and task completion. The model is served with vLLM and retains five screenshots in context, requiring the server to admit at least six images.
Developers outside China can now use a competitive open-weight GUI agent at 9B scale, reducing the cost and complexity of building desktop automation tools compared to larger models or closed APIs.
UI-Mate-9B enables businesses to automate desktop workflows with an open-weight model, avoiding per-API-call costs and allowing self-hosting for data privacy. Its Apache-2.0 license permits commercial use.
Adoption can be tracked through GitHub forks, Hugging Face downloads, and integration into open-source agent frameworks. Tencent may release larger variants or updates based on community feedback.
