}HappyHorse 1.1 Reference
HappyHorse 1.1 reference-to-video. image_urls is required (1-9 images) — this model blends reference images and does not support pure text-to-video. Reference each image in the prompt as [Image 1], [Image 2], etc.
Pricing — per second of generated video, in tokens (USD at $0.02/token). Limited-time offer: 20% below official pricing.
| resolution | tokens/s | our price /s | official /s |
|---|---|---|---|
| 720p | 5.2 | $0.104 | $0.13 |
| 1080p | 7.2 | $0.144 | $0.18 |
Example: a 5s 720p video costs 26 tokens (= $0.52).
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.
