HappyHorse 1.0 is a next-generation AI video model ranked #1 on the Artificial Analysis Video Arena for both text-to-video (Elo 1333) and image-to-video (Elo 1392). It generates native 1080p video with advanced motion synthesis, multi-shot character consistency, and multilingual support across six languages.
The Artificial Analysis Video Arena ranks models through blind user voting — participants compare two videos generated from the same prompt without knowing which model made which, then pick the better result. Votes feed into an Elo rating system. It holds the highest Elo in both text-to-video and image-to-video (no audio) categories as of April 2026.
The model outputs native 1080p HD resolution. Video includes rich color grading, accurate lighting, and film-grade detail suitable for broadcast and professional production without additional post-processing.
Yes. The model generates synchronized audio alongside video in one pass — including dialogue, ambient sounds, and Foley effects. It ranks #2 in the with-audio categories on the Artificial Analysis leaderboard.
Six languages are natively supported: Chinese, English, Japanese, Korean, German, and French. Prompts in any supported language produce high-quality video with full linguistic nuance.
Multi-shot storytelling allows the model to generate video sequences with multiple shots while maintaining consistency in characters, wardrobe, visual style, and atmosphere across scene transitions — eliminating the need for manual editing between clips.
Yes. The model supports both text-to-video and image-to-video through a unified pipeline. Upload a static image to animate it with intelligent motion synthesis, or describe a scene entirely through text.
