Alibaba has officially claimed ownership of the 'HappyHorse' AI video generation model, developed by its innovation division, ATH (Alibaba Token Hub). The announcement on April 10 follows days of market speculation about the model's origins. 'HappyHorse' has quickly risen to prominence, topping the text-to-video leaderboard on the evaluation platform Artificial Analysis with an Elo score of 1357. The model is noted for its ability to generate synchronized audio-visual content efficiently, potentially reducing post-production costs by over 50%. This development is part of Alibaba's broader strategic push into AI, marked by rapid product iterations and significant advancements in its AI capabilities. The company has recently launched several AI models, including Qwen3.6Plus, which set a global usage record. Alibaba's AI strategy aims to transition from fragmented efforts to a systematic approach, leveraging its full-stack AI capabilities to redefine its business foundation from e-commerce to AI-driven solutions.
