Qwen-AgentWorld (language world models for agents)

Alibaba (Qwen) · 22 June 2026

Language world models (35B-A3B and 397B-A17B) that simulate agent environments across seven domains, trained on 10M+ interaction trajectories.

Generalises WebWorld to models that predict an environment's next state with long chain-of-thought, trained in three stages (continued pretraining, SFT, RL with rubric-and-rule rewards) and scored on AgentWorldBench. Only the 35B-A3B checkpoint is on Hugging Face.
