Tencent Hunyuan opens HY-World 2.0 for persistent 3D worlds
Tencent Hunyuan expanded HY-World 2.0 beyond its April release by publishing HY-Pano 2.0 inference code and weights on May 11, then world-generation inference code plus WorldStereo 2.0 weights on May 18.
Tencent's official HY-World 2.0 repository added HY-Pano 2.0 inference code and weights on May 11, 2026, then added world-generation inference code and WorldStereo 2.0 weights on May 18, 2026.
Why visitors should care
This keeps HY-World 2.0 current as a source-backed Tencent reference for generated 3D worlds. The May 2026 repo updates materially improve reproducibility and make the open technical surface stronger without turning HY-World 2.0 into a polished public creator product.

Definition
What does World Models Watch count as a world model?
The site tracks systems that model environments, actions, spatial structure, or persistent simulated state. Pure text chatbots and ordinary video generators are only included when they provide a clear bridge toward interactive or physical world modeling.
Category boundary
Why do some AI video systems appear on a world-model site?
Video models are included only when they help explain the path from generated clips to controllable spaces, physics-aware prediction, or agent-ready simulation. The site keeps that distinction explicit so video generation is not overstated as a finished world simulator.
Editorial policy
How does the site decide whether a release is reliable enough to list?
Primary sources carry the most weight: official product pages, research posts, papers, documentation, code repositories, and company announcements. Secondary media can be referenced, but it stays labeled as reported or adjacent unless independently confirmed.
