Strengths & weaknesses
Strengths
- Editable 3D outputs (mesh, 3DGS, point cloud) rather than transient video
- Open weights and inference code; free online trial
- Generated worlds support first/third-person navigation with physics-based collision; render in real time on consumer GPUs
Weaknesses
- Licence excludes the EU, UK and South Korea and needs Tencent's permission above 1M MAU
- Components were released in stages (full world-generation code only from 2026-05-18)
Staged release: 2026-04-16 tech report + WorldMirror 2.0 weights; 2026-05-11 HY-Pano 2.0; 2026-05-18 world-generation code + WorldStereo 2.0 weights. GitHub README announces an 'HY World 2.1' update (July 2026) linked to the product page, with no model card or weights — not added as a separate entry. commercialUse true with conditions: licence grant is royalty-free within the Territory (worldwide excl.
