HunyuanVideo: Tencent's Open-Source Video Model
Tencent's open-weight video model for local text-to-video experimentation, often used through ComfyUI repackages.
Quick answer
HunyuanVideo is Tencent's open-source video generation model line, with weights published on HuggingFace.
Worth it if you want an open local model and have the GPU for it — this is heavier than LTX-Video.
There is no per-video model fee for self-hosting, but cloud GPU rental or high-end local hardware can dominate the actual cost.
01HunyuanVideo vs HunyuanVideo 1.5
Both releases are open-weight. Pick based on tooling compatibility and VRAM budget.
| HunyuanVideo | HunyuanVideo 1.5 | |
|---|---|---|
| Positioning | Original open video model | Updated model line |
| Weights | Open · HuggingFace | Open · HuggingFace |
| Model fee | $0 | $0 |
02Generation modes
HunyuanVideo is primarily a local/open model workflow rather than a polished consumer app.

03Run locally
HunyuanVideo can run locally, but it is not the low-VRAM choice. If you rent compute, HuggingFace GPU examples start at $0.40/hour and 24 GB options start around $0.80–$1.00/hour.
VRAM by GPU
| Setup | Concrete cost | Best for | Notes |
|---|---|---|---|
| High-VRAM local GPU | $0 model fee + your hardware | Frequent local testing | Check model card for exact VRAM |
| Cloud GPU | HF examples: T4 $0.40/hr, L4 $0.80/hr, A10G $1.00/hr | Occasional large runs | Avoids buying a high-end card |
| Quantized community build | $0 model fee + setup time | Consumer GPUs | Quality/speed trade-off |
04Official pricing & registration
HunyuanVideo has no per-video model fee because the weights are open. To make the price concrete, use compute pricing: HuggingFace Spaces lists CPU Basic as free, Nvidia T4 small at $0.40/hour, Nvidia L4 at $0.80/hour and Nvidia A10G small at $1.00/hour.

06vs the competition
Short version: HunyuanVideo is better for heavier open-model experiments. LTX-Video is better when low VRAM and fast local iteration matter more.

Is HunyuanVideo open source?
Yes — weights are public on HuggingFace under the tencent organization.
Can HunyuanVideo run locally?
Yes, typically via ComfyUI repackaged builds. VRAM needs are significant; check the model card for exact figures.
How much does HunyuanVideo cost?
Self-hosting the open weights has no per-video model fee. Budget for GPU hardware, electricity or rented cloud GPU time.
