UI-Venus-2, an AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → for mobile, web and desktop interfaces, checks recorded interactions against visible evidence when selecting training data. Its technical report describes breaking a task into observable milestones and examining screenshots to determine which were reached.
For example, a trace that enters the right group and fills in a post but runs out of steps before confirming publication is labeled partial rather than failed. Such traces can be reviewed and repaired, while completed traces enter a higher-quality candidate pool. The mechanism separates unfinished but useful interactions from successful ones before they are used to develop the agent.
