OmniHuman AI Avatar
OmniHuman is ByteDance's audio-driven human video model: give it a portrait and speech, and it animates the face and upper body in sync. It is the engine behind our talking avatar. The composer below is in Avatar mode and needs a portrait plus uploaded or generated audio; the spec table is live from the registry.

Frequently asked
- Does it work with illustrated faces?
- Often, yes; results improve the more human-like the face is.
- Can I use it for a saved character?
- Yes. Attach the character in Avatar mode and its reference portrait is used.
- Do I have to pick an AI model?
- No. Choose a style preset such as Fast, Cinematic or Story and the router selects the best available model for that intent, aspect ratio, duration and the inputs you attached. If a model is degraded, the router falls back to a comparable one without charging you twice. Advanced users can still pin a specific model.
- How much does a generation cost?
- Every generation is quoted in credits before you confirm, based on the routed model, duration and resolution. Credits are reserved when you start and released automatically if the generation fails, so you only pay for what completes. Plans start at $4.99 a week and include a credit allowance; subscribers can top up with credit packs.
- What happens if a generation fails?
- The reserved credits are released back to your wallet immediately. If the failure was on the provider side and a fallback model can serve the same request, the router retries automatically and you are still charged once.
