HunyuanVideo
Tencent · Video · 13B
HunyuanVideo is one of the stronger open text-to-video models, generating up to 720p at up to 129 frames. It is firmly a high-VRAM model: the card states a minimum of 45GB for 544p output and 60GB for 720p, with an 80GB card recommended for best quality, though FP8 weights cut memory by around 10GB. It runs from the official repo or through diffusers. The licence is a custom Tencent community licence, so it is classified here as conditional rather than freely permissive. A much lighter HunyuanVideo 1.5 exists separately for those who cannot meet these memory requirements.
Strengths
- Strong quality among open text-to-video models
- Up to 720p and 129 frames
- FP8 weights available to reduce memory somewhat
Weaknesses
- High VRAM: 45GB minimum, 60GB for 720p, 80GB recommended
- Licensed territory excludes the UK, EU and South Korea, so UK users are not licensed to use the model or its outputs
- A custom Tencent community licence, not standard open source
- Not runnable on consumer cards without the lighter 1.5 version
