UI-Venus-2 Brings GUI Agents to Real-World Apps
๐กSee how UI-Venus-2 tackles cross-platform GUI automation, reward verification, and safe consequential actions.
โก 30-Second TL;DR
What Changed
Supports more than 170 multilingual mobile apps along with native desktop operating systems.
Why It Matters
UI-Venus-2 could make GUI automation more transferable beyond narrow benchmarks by improving environment diversity and reward reliability. Its open-source availability may help developers prototype agents for cross-platform workflows, although real-world reliability and safety still require independent validation.
What To Do Next
Download the open-source UI-Venus-2 release when available and benchmark it in a sandbox on three representative workflows across mobile, web, and desktop interfaces.
Key Points
- โขSupports more than 170 multilingual mobile apps along with native desktop operating systems.
- โขUses a unified closed-loop reasoning-action framework across mobile, web, and desktop interfaces.
- โขImproves reinforcement-learning signals with trace-level and sample-level evaluators, visual keypoints, and multi-model voting.
- โขAdds safety-aware controls for consequential actions during automated GUI execution.

๐ Enhanced Key Takeaways
- โขThe model utilizes the Qwen3.5-9B architecture as its foundational language backbone for GUI grounding.
- โขUI-Venus-2 achieved an 11.3% Attack Success Rate on the OSHarm benchmark, indicating a measurable improvement in safety against adversarial GUI inputs.
- โขThe agent introduces 'VenusBench-CAPTCHA' as a specialized benchmark to test agent robustness against security-oriented interface challenges.
- โขPerformance metrics include a 70.8 score on the OSWorld benchmark and 80.2 on AndroidWorld, outperforming several larger parameter-count models.
- โขThe training pipeline incorporates verification-augmented reflection, allowing the agent to distinguish between partial task progress and final completion to improve long-horizon recovery.
