## Pick the right model for the user's intent

Listed newest first. The agent classifies user intent — pre-recorded audio file or just a script? Photoreal portrait or stylized character? Single shot or cinematic composition? — and picks one route below.

**OmniHuman** — `bytedance/omnihuman/api` *(default)*
> ByteDance audio-driven full-body avatar. Feed one portrait + one audio file, get back a video where the subject speaks / sings / gestures naturally. Listed on RunComfy's `/feature/lip-sync` as the curated default.
> Pick for: UGC voiceover, virtual presenter, dubbed product demo, multi-language clips from same portrait.
> Avoid for: no audio file available (need to generate speech from a script) — use **HappyHorse 1.0**.

**HappyHorse 1.0** — `happyhorse/happyhorse-1-0/text-to-video` (t2v) · `happyhorse/happyhorse-1-0/image-to-video` (i2v)
> Arena #1 t2v / i2v with in-pass audio generated from prompt. No external audio file required — quote the spoken line inside the prompt.
> Pick for: written script with no audio file, "write a script → get a video", concept clips, i2v talking-head from an existing portrait.
> Avoid for: precise lip-sync to a specific MP3 — audio is regenerated each call, not locked.

**Seedance v2 Pro** — `bytedance/seedance-v2/pro`
> ByteDance multi-modal flagship — up to 9 reference images, 3 reference videos, 3 reference audio tracks composed in one pass with cinematic motion / lens / lighting control.
> Pick for: cinematic monologue with reference subject +
