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`

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`

Faster variant of Seedance v2 Pro, same multi-modal capabilities. Pick for: iteration on Seedance v2 compositions before locking a final on Pro. Avoid for: hero-shot final delivery.

Wan 2-7 — wan-ai/wan-2-7/text-to-video

Open-weights flagship, audio_url field for audio-driven lip-sync, pairs natively with Wan image models. Pick for: dialog scenes where mouth must sync to a specific voiceover file; open-weights pipeline requirement. Avoid for: in-pass audio generation (no MP3 input) — use HappyHorse 1.0.

Kling 2-6 Pro — `kling/kling-2-6/pro/text-to-video`

Previous Kling tier — still strong quality at much lower cost than 3.0 4K. Pick for: production at scale where 3.0 4K is too expensive. Avoid for: top-tier hero shots — use Kling 3.0 4K.

Seedance 1-5 Pro — `bytedance/seedance-1-5/pro/text-to-video`

Previous Seedance generation, cheaper. Pick for: identity-stable batches between 1-5 generations; cost-sensitive baseline. Avoid for: new work — prefer Seedance v2 Pro or Fast.

Image-to-video (i2v) — newest first

HappyHorse 1.0 I2V — happyhorse/happyhorse-1-0/image-to-video (default)

Animate any still with in-pass audio described in prompt, strong identity preservation. Pick for: animating a generated portrait or product still, vertical social clips, voiceover-described audio. Avoid for: physics-accurate object motion — use Veo 3-1.

Veo 3-1 — `google-deepmind/veo-3-1/image-to-video`

Google's flagship — physics-respecting motion, strong object permanence ("rotates 180 degrees" = 180°), pairs with extend-video for longer clips. Pick for: product spins, physics-accurate motion, scenes where "no other motion" must hold. Avoid for: audio-driven dialog — use Wan 2-7 or HappyHorse.

Veo 3-1 Fast — `google-deepmind/veo-3-1/fast/image-to-video`

Faster Veo 3-1 variant. Pick for: iteration on Veo compositions. Avoid for: hero delivery — use full Veo 3-1.

Kling 3.0 4K I2V — `kling/kling-3.0/4k/image-to-video`

Multi-shot character identity, 4K output from a still. Pick for: 4K hero shots, character-narrative cuts. Avoid for: cost iteration — drop to Pro or Standard.

Kling 3.0 Pro I2V — `kling/kling-3.0/pro/image-to-video`

Default Kling 3.0 quality tier. Pick for: high-quality i2v at moderate cost. Avoid for: 4K final delivery.

Kling 3.0 Standard I2V — `kling/kling-3.0/standard/image-to-video`

Cheapest 3.0 i2v tier. Pick for: concepting / drafts on Kling 3.0. Avoid for: final delivery.

Hailuo 2-3 Pro — `minimax/hailuo-2-3/pro/image-to-video`

MiniMax Hailuo latest — natural motion, strong on real-world subjects. Pick for: lifelike motion of real-people / real-product subjects. Avoid for: stylized characters — use Kling or Dreamina.

Dreamina 3-0 Pro — `bytedance/dreamina-3-0/pro/image-to-video`

ByteDance Dreamina i2v — illustration / stylized character lean. Pick for: animating illustrated heroes, painterly stills. Avoid for: photoreal motion.

Seedance 1-0 Pro Fast — `bytedance/seedance-1-0/pro/fast/image-to-video`

Older Seedance i2v generation, cheap. Pick for: cost-sensitive batch i2v on Seedance. Avoid for: new work — Seedance v2 Pro is more capable (t2v + i2v + multi-modal).

Extend an existing video — newest first

Veo 3-1 Extend — `google-deepmind/veo-3-1/extend-video`

Continue an existing Veo clip with consistent motion / lighting / identity.
