What changed

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.

Context summary

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.

FAQ

Before you comment

A compact guide to source confidence, category boundaries, and reader participation before adding a note.

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.

Community

What should readers post in comments?

Useful comments add source links, corrections, release-status notes, comparison questions, or concrete reader context. Comments are public immediately, so readers should avoid private information and unsupported promotional claims.
