About Happy Horse AI
Why this site exists
On 2026-04-07, a new AI video model called HappyHorse-1.0 appeared on the Artificial Analysis text-to-video and image-to-video leaderboards — and immediately took the #1 spot on both, beating ByteDance Seedance 2.0, SkyReels V4, Kling 3.0, grok-imagine-video, and PixVerse V6.
What made the launch unusual is that the developer published nothing else. No website. No paper. No API endpoint. No GitHub release. Just two leaderboard entries with the developer field set to "HappyHorse" and an API status of "Coming soon".
Within 48 hours, more than 18 templated SaaS-clone sites had spun up across the happyhorse* / happy-horse* / happyhorseai* domain namespace, almost all of them recycling the same generic copy: vague superlatives, undated leaderboard claims, and recycled marketing language. None of them cited the leaderboard with a date. Several of them quietly use Google Veo or ByteDance Seedance under the hood and present themselves as HappyHorse-1.0.
We built happy-horse-ai.pro to be the opposite of those sites.
What this site is
This is an unofficial, independent informational site about HappyHorse-1.0. It is run by independent contributors and is not affiliated with the developer of HappyHorse-1.0.
We do exactly three things:
- Show the verified leaderboard data — every numeric claim on this site links to its source on artificialanalysis.ai and carries a "data verified on" date that ages visibly if it goes stale.
- Tell you what is not known — model architecture, parameter count, training data, supported resolutions, lip-sync support, license, pricing, API endpoint. We list these as unknowns rather than making them up.
- Let you join a waitlist so we can email you exactly once, when the official API actually ships.
That's the whole site. There is no video generator here. There is no upsell. There are no accounts. There is no Google Analytics. There are no cookies.

Who runs this
This site is built and maintained by independent contributors who follow the open AI video space. We do not represent the HappyHorse-1.0 team in any way. If the official team would like to contact us, please write to the email below — we will respond within 7 days and are happy to take down or correct anything they ask us to.
When the API ships
The moment the official HappyHorse-1.0 API becomes publicly available, we will:
- Update this site to link directly to the official source.
- Email everyone on the waitlist exactly once.
- Re-evaluate whether this site is still useful, or whether we should redirect to the official one.
