Why HappyHorse-1.0 Is #1
Leaderboard Performance
#1 in Blind Human Preference
HappyHorse-1.0 holds the top Elo rating on the Artificial Analysis Video Arena in both Text-to-Video and Image-to-Video (no audio). Rankings are based on blind preference votes from real users who do not know which model produced the output they are voting on.
Joint Audio-Video Generation
Video and Sound in a Single Pass
The model reportedly generates video and audio jointly in a single forward pass using a unified 40-layer self-attention Transformer with no cross-attention modules. This architecture produces synchronized audiovisual output without separate audio post-processing.
Inference Speed
1080p in Under 40 Seconds
The team claims approximately 38-second generation time for 1080p output on a single NVIDIA H100 GPU, and roughly 2 seconds for a 5-second clip at 256p. If verified, this would represent a significant speed advantage over current alternatives.

HappyHorse AI video model workflows
HappyHorse AI model
HappyHorse is positioned around HappyHorse-1.0, an AI video model for text-to-video and image-to-video generation with native synchronized audio. Use it when the final clip needs motion, dialogue, ambience, or Foley to feel connected from the first render.
- Use text prompts for concept shots and scene exploration.
- Use image inputs when a character, product, or composition must remain recognizable.
- Use native audio when dialogue, sound effects, or atmosphere matter.

HappyHorse API intent
HappyHorse API searches should land on a page that explains which model variant is available, what inputs are accepted, how duration and resolution are controlled, and how the output video and audio are returned.
- Check whether the endpoint supports text-to-video, image-to-video, or video edit.
- Log prompt, duration, resolution, input assets, and returned media URLs.
- Test audio behavior early if your product depends on lip-sync or sound timing.

FAQs
What is HappyHorse-1.0?expand_more
HappyHorse-1.0 is Alibaba's flagship AI video model with native synchronized audio generation. On fal.ai it is exposed through separate text-to-video, image-to-video, reference-to-video, and video-edit workflows under one Happy Horse 1.0 family.
How does joint audio-video generation work?expand_more
HappyHorse-1.0 processes audio and video tokens together in the same 40-layer Transformer, rather than generating video first and adding audio in a separate step. This allows the model to learn the natural correlation between sound and visual content — so lip movements match dialogue, Foley sounds align with on-screen actions, and ambient audio shifts as the scene evolves.
What video resolutions and durations are supported?expand_more
The current fal.ai Happy Horse 1.0 endpoints support 720p and 1080p. Text-to-video, image-to-video, and reference-to-video support 3 to 15 second outputs. Video edit keeps the source aspect ratio and matches the input duration, capped to the first 15 seconds.
Which languages does the lip-sync support?expand_more
HappyHorse-1.0 supports phoneme-level lip synchronization in 7 languages: English, Mandarin Chinese, Cantonese, Japanese, Korean, German, and French.
Can I generate videos without audio?expand_more
The current fal.ai Happy Horse generation endpoints produce native audio by default and do not expose an audio off switch. In video-edit mode you can choose `audio_setting: origin` to preserve the original input audio instead of regenerating it.
Can I use HappyHorse-1.0 for free?expand_more
Yes. After creating an account you receive free credits to try HappyHorse-1.0. For unlimited generations, higher resolution outputs, or longer clips, a paid plan is required.
