About
UI-Mate-9B UI-Mate: Advancing Open-Weight Foundation GUI Agents with In-Context Demonstrations Show the workflow once. Let the agent adapt it to the task at hand. Tencent HY Frontier Project Page · GitHub · arXiv Overview 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. It executes a task from a natural-language instruction and live screenshots alone, planning from what is currently on screen and re-planning as the interface changes. Model Details - Parameters: 9B - Base model: Qwen3.5-9B - Input: task instruction, screenshots, and interaction history - Output: reasoning, a concise action description, and structured computer-use tool calls - Action space: mouse, keyboard, scrolling, waiting, user interaction, and task completion - Training: supervised fine-tuning followed by online reinforcement learning in executable GUI environments - License: Apache-2.0 UI-Mate is an agent checkpoint rather than a standalone visual-chat model. We recommend using the official prompt, response parser, and interaction harness from the UI-Mate repository. Highlights - Strong general computer-use performance at an efficient 9B scale. - Long-horizon execution across multiple applications. - Live-screen grounding instead of coordinate replay. - Structured actions compatible with pyautogui. - OpenAI-compatible serving and client interface. Evaluation See the project page for evaluation details and updates. Quick Start 1. Serve the model with vLLM vLLM automatically downloads the checkpoint from Hugging Face Hub on first launch. The default agent retains five screenshots in context. The server must therefore admit at least six images because the newest screenshot arrives before the oldest one is collapsed. Confirm that the endpoint exposes the expected model name: 2. Run the reference examples Run a complete recorded trajectory: Or provide your own screenshot: 3. Use the Python agent Intended Use and Limitations UI-Mate-9B is intended for research and development of screenshot-

How it works
Variants
Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.
Using it via the API
Once AxForge deploys ui-mate for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (ui-mate below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/chat/completions \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"ui-mate","messages":[{"role":"user","content":"Hello"}]}'
Licence
