# OmniHuman API

OmniHuman API access for audio-driven talking-head video, human identification, and subject-mask detection.

**Provider:** Bytedance
**Modality:** Utility
**Catalog:** 3 variants

OmniHuman generates talking-head video from a source image and driving audio. Helper endpoints can identify human regions and return subject masks that can be passed into the audio-to-video request.

## FAQ

### Which variant should I start with?

Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.

### Is there a free tier?

New accounts get free first calls on every model. After that, pay per call.

### Do you stream results?

Where streaming is available, RunAPI streams end-to-end.

### How are failures billed?

Failed generations are not charged.

### Are outputs cached?

Generated outputs are stored and retrievable by task ID. Inputs are not cached.

### Can I use commercially?

Yes — commercial use is included for every variant unless a model license explicitly restricts it, which is called out on the variant page.

### What about rate limits?

Per-key rate limits scale with usage tier. See pricing page for current limits.

### Where can I report issues?

Open an issue on the public GitHub repo or email support.
