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

### Text-to-video (t2v) — newest first

**HappyHorse 1.0** — `happyhorse/happyhorse-1-0/text-to-video` *(default)*
> Currently #1 on Artificial Analysis Video Arena. Native synchronized audio generated in-pass (no separate Foley step). Native 1080p, up to ~15s, strong multi-shot character consistency.
> Pick for: general-purpose t2v, ad creative with audio, social-media clips, multi-shot narratives.
> Avoid for: audio-driven lip-sync to a specific voiceover MP3 — use **Wan 2-7**.

**Kling 3.0 4K** — [`kling/kling-3.0/4k/text-to-video`](https://www.runcomfy.com/models/kling/kling-3.0/4k/text-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)
> Kling's latest, 4K output, strong multi-shot character identity, premium camera language.
> Pick for: hero shots, final-delivery 4K cuts, multi-shot character narratives.
> Avoid for: cost-sensitive iteration — drop to **Kling 2-6 Pro** or **Standard** i2v.

**Seedance v2 Pro** — `bytedance/seedance-v2/pro`
> ByteDance flagship — multi-modal (up to 9 reference images, 3 reference videos, 3 reference audio), in-pass synchronized audio, cinematic motion refinement, lens language honored.
> Pick for: cinematic ad frames, multi-reference composition (subject + scene + audio refs), 21:9 anamorphic looks.
> Avoid for: simple "single prompt → clip" jobs — overpowered, slower.

**Seedance v2 Fast** — [`bytedance/seedance-v2/fast`](https://www.runcomfy.com/models/bytedance/seedance-v2/fast?utm_source=skills.sh&utm_medium=skill&utm_campaign=ai-video-generation)
> Faster variant of
