}'Why HappyHorse 1.1
Four modes in one model family
Text-to-video, image-to-video, reference-to-video, and video extend — all under Alibaba HappyHorse 1.1. Switch between them by changing one model slug.
720p and 1080p output
720p starts at $0.53 per 5 seconds for fast iteration. 1080p starts at $0.94 per 5 seconds for final delivery. Pricing scales linearly with duration.
Sharper than HappyHorse 1.0
The 1.1 release improves cinematic motion, subject consistency, and prompt adherence — especially good for character continuity across reference-to-video and extend chains.
Unified Hypereal API
Same /v1/videos/generate endpoint as Seedance, Kling, Veo, Sora 2, and WAN 2.7. Switch model slugs to A/B compare without re-integrating.
Questions fréquemment posées
What is HappyHorse 1.1?
HappyHorse 1.1 is the latest release of Alibaba's cinematic AI video generation model, available on Hypereal in four modes: text-to-video, image-to-video, reference-to-video, and video extend.
Which HappyHorse 1.1 modes are available?
All four: T2V (text-to-video), I2V (image-to-video), Ref2V (reference-to-video), and video extend (continue an existing clip). They all share the same /v1/videos/generate endpoint.
How is HappyHorse 1.1 priced?
All modes share the same rate: $0.53 per 5-second 720p video or $0.94 per 5-second 1080p video. Pricing scales linearly with duration, so a 10-second clip costs 2x a 5-second clip.
How is HappyHorse 1.1 different from 1.0?
HappyHorse 1.1 improves cinematic motion, subject consistency, and prompt adherence over 1.0 while keeping the same per-second pricing. Both versions remain available — switch by changing the model slug.
Can I use multiple reference images?
Yes. happyhorse-1-1-ref2v accepts an images array of reference URLs for character or style consistency across the generated clip.
Can I extend an existing video?
Yes. Use happyhorse-1-1-video-extend to seamlessly continue from the last frame of an existing clip.
