Tongyi Qianwen releases its first native language world model Qwen-AgentWorld

ME AI News, according to Data Observation Beating monitoring, the Tongyi Qianwen team officially released Qwen-AgentWorld today. This is the first native language world model that sets environment modeling as a training goal starting from the continued pre-training stage, rather than an adaptation of a general large model in later stages. The model simultaneously covers seven major domains under a single framework: text-based environments (MCP, Search, Terminal, SWE) and GUI-based environments (Web, OS, Android), based on over 10 million real environment interaction trajectories, trained through CPT→SFT→RL three-stage process, achieving cross-domain knowledge transfer. Also open-sourced is the AgentWorldBench evaluation benchmark, where each test sample is paired with observed data obtained from real environment execution. The model and benchmark are now available on Hugging Face and ModelScope. In the AgentWorldBench evaluation, Qwen-AgentWorld-397B-A17B achieved the highest overall simulation quality, surpassing GPT-5.4, Claude Opus 4.8, and Gemini 3.1 Pro. The research team also explored two application paths of world modeling in intelligent agent training: as a decoupled environment simulator, where controllable simulation RL can shape agent behavior and significantly outperform RL trained only in real environments; and as a unified foundation model for intelligent agents, where LWM pretraining can transfer to multi-round agent tasks covering seven benchmarks, three of which are completely unseen during training, and without the need for RL fine-tuning on agent tasks. This preliminarily validates the potential of language world models as more powerful foundational models for intelligent agents.
