Strengths & weaknesses
Strengths
- Real-time streaming at 24 FPS with keyboard/mouse control
- Reconstituted context memory for long-term geometric consistency
- Open training code, inference code and weights; online demo
Weaknesses
- Only a 480p model released
- Licence excludes the EU, UK and South Korea and needs Tencent's permission above 1M MAU
Included alongside HY-World 2.0 because it is a separate, still-offered line (real-time video stream vs 3D asset generation). HF card: 'Now we only provide the 480p model' (secondary coverage claims 720p — not on primary pages). No max length stated ('infinite world extension'; default 125 frames). Built on HunyuanVideo 1.5. commercialUse true with the same territory/MAU conditions as HY-World 2.0.
