🚀 Bridging the Gap: The Legacy of Happy Horse, Seedance, and Sora—Reshaping the Landscape of AI Video Generation and a Practical Guide
As artificial intelligence video generation technology enters an explosive growth period, the market landscape underwent a dramatic shift in March 2026. Based on the latest industry developments, this article provides an in-depth comparison of the phenomenal model **Happy Horse 1.0** (Alibaba ATH's innovative model, representing a new peak of theoretical potential) and the stably deployed **Seedance 2.0** (representing current industrial-grade usability), while also analyzing the legacy and lessons left by the announced shutdown of **Sora**. The research finds that in terms of performance data, Happy Horse demonstrates a crushing theoretical advantage; however, from an engineering practice perspective, Seedance, with its ease of use and immediate availability of "director-level control," is currently the best choice for commercial implementation. The exit of Sora, meanwhile, signals that a model solely focused on "showcasing technical prowess" without a clear commercialization path is unsustainable.
