Qwen WebWorld 32B/14B/8B: Open-Web World Model for Web Agent Training
Integrate the WebWorld 32B model from Hugging Face into your web‑agent training pipeline to achieve +9.9% MiniWob++ and +10.9% WebArena gains, and use it as a look‑ahead world model that outperforms GPT‑5.
Integrate the WebWorld 32B model into your agent training pipeline, benchmark against existing models, and evaluate look‑ahead search performance.
Summary
Qwen has released the WebWorld series, a large‑scale open‑web world model trained on 1M+ real‑world web interaction trajectories using a scalable hierarchical data pipeline. The model supports long‑horizon simulation of 30+ steps, multi‑format state representations—including A11y Tree, HTML, XML, Markdown, and natural language—and chain‑of‑thought activated reasoning for transition prediction. It generalises across domains such as code, GUI, and game environments. Benchmarks show a +9.9% improvement on MiniWob++ and +10.9% on WebArena, and the model outperforms GPT‑5 as a look‑ahead world model during inference. WebWorld is available in 32B, 14B, and 8B variants on Hugging Face.
The release provides developers with a powerful tool for training and evaluating web agents, offering richer state representations and higher‑fidelity simulation. By leveraging the hierarchical data pipeline, users can quickly integrate WebWorld into existing agent pipelines and achieve significant performance gains across multiple benchmarks.
