Frequently Asked Questions

Common questions about HappyHorse 1.0 video generation

HappyHorse 1.0 is Alibaba's flagship AI video model, ranked #1 on the Artificial Analysis leaderboard as of April 2026. Built on a single-stream Transformer architecture with approximately 15B parameters, it delivers state-of-the-art motion stability, prompt adherence, and visual fidelity across a unified pipeline.
HappyHorse exposes 5 endpoints covering the full creative lifecycle: text-to-video, image-to-video, reference-to-video (using subject or style references), prompt-driven video editing, and video extension. All endpoints support 720p and 1080p output with durations from 3 to 15 seconds.
Generated clips can run from 3 to 15 seconds, with a default of 5 seconds. Pricing scales linearly with duration, so a 10-second clip costs exactly twice as much as a 5-second clip at the same resolution.
HappyHorse supports five aspect ratios: 16:9 (landscape), 9:16 (portrait), 1:1 (square), 4:3 (classic), and 3:4 (portrait classic). This covers cinematic, social, and traditional formats out of the box.
HappyHorse uses straightforward per-second pricing: 20 credits per second at 720p and 35 credits per second at 1080p. Total cost equals credits-per-second multiplied by duration. For example, a 5-second 720p clip costs 100 credits, and a 5-second 1080p clip costs 175 credits.
As of April 2026, HappyHorse 1.0 ranks #1 on the Artificial Analysis leaderboard for both text-to-video and image-to-video, ahead of Seedance 2.0 and Wan 2.7. Its single-stream Transformer architecture delivers particularly strong motion stability and prompt adherence compared to dual-branch and MoE-style competitors.
