Alibaba just open-sourced a world model that lets AI agents train inside a simulator
Alibaba's Qwen team released Qwen-AgentWorld, a language world model that simulates agent environments across seven domains. Its three-stage pipeline, CPT, SFT, RL, produces a simulator that beats GPT-5.4 on fidelity and enables agents to train via mental rehearsal rather than costly real-environment rollouts.
