SAN FRANCISCO, Calif. – April 10, 2026 – <\/strong>A previously unknown artificial intelligence video generator named Happy Horse<\/a> 1.0 has reached the No. 1 position on the Artificial Analysis Video Arena, the leading independent benchmark for ranking AI video generation models. According to current public data, Happy Horse 1.0 holds an Elo rating of 1,374<\/strong> on the text-to-video (no-audio) leaderboard, ahead of ByteDance Seed’s Dreamina Seedance 2.0 720p at 1,273 — a separation of 101 points.<\/p>\n

The lead has been built across 7,932 blind user comparisons<\/strong>, with a 95% confidence interval of ±9. The same model has also reached No. 1 on the with-audio leaderboard<\/strong> (Elo 1,222), making Happy Horse 1.0 the only AI video generator currently topping both Artificial Analysis tracks simultaneously.<\/p>\n

On preference-based benchmarks, a 100-point Elo gap paired with a 95% confidence interval that does not overlap with the next-ranked model is generally treated as a decisive separation rather than statistical noise. In the Video Arena’s tracked history, that pattern has typically signaled a meaningful step change in model quality rather than short-term sampling variance.<\/p>\n

Happy Horse 1.0 currently leads a competitive field that includes Skywork AI’s SkyReels V4 (Elo 1,244), KlingAI’s Kling 3.0 1080p Pro (1,242), xAI’s grok-imagine-video (1,230), Runway Gen-4.5, Google Veo 3.1, and OpenAI Sora 2 Pro. Artificial Analysis ranks all entries using blind pairwise voting, in which users compare two unlabeled videos generated from the same prompt and select the one they prefer. The methodology is widely viewed as the video-generation equivalent of LMArena, the long-running benchmark for large language models.<\/p>\n

Happy Horse 1.0’s strength reportedly comes from its prompt adherence<\/strong>, scene continuity<\/strong>, and cinematic motion realism<\/strong> in high-definition video synthesis — three dimensions where most current AI video generators have struggled to keep pace with user expectations. The model also delivers native audio-video joint output, a capability that has historically lagged behind silent video generation in arena testing.<\/p>\n

As of publication, no organization has officially claimed authorship of Happy Horse 1.0. The most widely circulated theory in Chinese-language technology media links the model to a new research team reportedly led by Zhang Di<\/strong>, a vice president at Kuaishou and the head of its large-model team — the group that oversees the Kling video generation effort. According to those reports, Zhang reportedly joined Alibaba in late 2025 to head a research unit known as the Future Life Lab inside the company’s Taotian Group. The attribution has not been independently confirmed by Alibaba or by any party associated with Happy Horse 1.0.<\/p>\n

If the attribution is accurate, the development would mark an unusual narrative arc in the AI video industry: a senior leader who oversaw one of the top-ranked closed video models on the same leaderboard would now be associated with a model that has surpassed it in blind user testing.<\/p>\n

Artificial Analysis lists the broader API status of Happy Horse 1.0 as “Coming soon,” and project documentation indicates plans for wider community access. A public early-access interface for testing the model is currently available at HappyHorses.io<\/a>, where users can test the leading AI video generator in their browser without registration. Leaderboard rankings are dynamic and may shift as additional user votes are collected.<\/p>\n

About HappyHorses.io<\/strong><\/p>\n

HappyHorses.io is an early-access portal and public testing interface for the Happy Horse 1.0 AI video generation model. The platform provides creators, developers, and researchers with browser-based access to the current No. 1 model on the Artificial Analysis Video Arena, supporting both text-to-video and image-to-video generation in cinematic high-definition output.<\/p>\n

About the Artificial Analysis Video Arena<\/strong><\/p>\n

The Artificial Analysis Video Arena is an independent crowd-preference benchmark for AI video generation models. It ranks systems using Elo scores derived from blind, side-by-side user comparisons — a methodology designed to be resistant to self-reported scores or curated demo material. Live rankings are publicly available at artificialanalysis.ai.<\/p>\n
