Watch AI videos created with Happy Horse on Happy Horse AI — story scenes, text-to-video clips, image-to-video motion, product demos, and cinematic 1080p outputs.
Happy Horse is a next-generation AI video model developed by the Alibaba ATH (Taotian) Future Life Lab team. Released in April 2026, Happy Horse anonymously reached #1 on the Artificial Analysis Video Arena for both text-to-video (Elo 1333) and image-to-video (Elo 1392) — surpassing closed-source models including Seedance 2.0, Kling 3.0 Pro, and PixVerse V6. Alibaba publicly confirmed authorship after the model went viral, a story covered by CNBC. Unlike traditional video models that generate silent clips, Happy Horse produces video and synchronized audio in a single forward pass — phoneme-level lip-sync in 7 languages, ambient Foley, and cinematic music. Built on a 15B-parameter unified Transformer with DMD-2 distillation, Happy Horse 1.0 supports text-to-video, image-to-video, reference-based generation, and advanced editing. Happy Horse AI is an independent creation platform that lets you use Happy Horse directly in the browser — no download, no GPU, no waiting on open-source weight releases.

The Model
A neutral technical overview of Happy Horse — the AI video model that powers Happy Horse AI. Also known as Happy Horse 1.0.
Happy Horse is a 15-billion-parameter video generation model released in April 2026. The release name is Happy Horse 1.0, commonly shortened to Happy Horse. The model was developed by the Alibaba ATH (Taotian) Future Life Lab team and was first submitted anonymously to the Artificial Analysis Video Arena before Alibaba confirmed authorship. Happy Horse has since dominated the leaderboard and attracted coverage from CNBC and the broader AI research community.
The Artificial Analysis Video Arena uses blind user voting — two outputs are shown side by side and users pick the preferred one. Votes feed into an Elo rating. Happy Horse currently holds Elo 1333 on text-to-video (no audio) and Elo 1392 on image-to-video (no audio), placing Happy Horse at #1 in both categories. With audio, Happy Horse holds #2 at Elo 1205 and 1161 respectively. All positions as of April 2026.
Most video models treat audio as a post-processing step. Happy Horse generates video and audio jointly inside a single 40-layer Transformer — the first and last 4 layers use modality-specific projections, the middle 32 layers share parameters across all modalities. Lip-sync is aligned at the phoneme level in 7 languages (English, Chinese, Japanese, Korean, German, French, Cantonese), with a reported Word Error Rate of 14.60%. A DMD-2 distillation stage reduces denoising to 8 steps, so Happy Horse 1.0 produces 1080p output fast enough for iterative creative work.
The Happy Horse GitHub and Hugging Face links are marked "coming soon" at the time of writing, so the official weights are not yet public. The fastest way to actually use Happy Horse right now is in the browser on Happy Horse AI — no download, no setup, first video free after sign-up.
Happy Horse delivers top-ranked motion quality, scene coherence, and prompt accuracy — validated by blind user voting on Artificial Analysis as of April 2026. Use Happy Horse online via Happy Horse AI.
