bitHuman

Surface	bitHuman product
Live	Real-time Avatars (ultra-low latency, ~200ms)
Render	Video Generation

Both surfaces use the same BITHUMAN_API_KEY. SDK: bithuman-go.

Live

Ultra-low latency real-time avatars — the lowest-latency option of the three providers (video quality is good rather than excellent, and voice cloning is not available).

provider, err := omniavatar.GetLiveProvider("bithuman",
    omniavatar.WithAPIKey(os.Getenv("BITHUMAN_API_KEY")),
    omniavatar.WithExtension("agent_id", "agent_xxx"),
)

Option	Description
agent_id	bitHuman agent ID (required)

Render

Asynchronous talking-head generation using bitHuman agents.

provider, err := omniavatar.GetRenderProvider("bithuman",
    omniavatar.WithAPIKey(os.Getenv("BITHUMAN_API_KEY")),
    omniavatar.WithExtension("agent_id", "agent_xxx"),
)

Option	Level	Description
agent_id	provider	Default agent ID
voice_id	request	TTS voice for Script input

Audio Upload

The bitHuman render provider implements render.AudioUploader via the bitHuman file API (base64 upload returning a hosted URL). Common audio formats are accepted; the MIME type is derived from the filename extension.

Limitations

Width, height, and background options are not supported by the bitHuman video API and are ignored by this provider.
