On the afternoon of April 8, the stock price of Alibaba-W (9988.HK) surged nearly 8%, reaching HK$127.9. The day before, a mysterious model named 'Happy Horse' appeared on the AI video evaluation platform Artificial Analysis, surpassing Seedance2.0 to claim the top spot globally. It is reported that 'Happy Horse' leads in terms of visual consistency, motion naturalness, and audio synchronization, while its price is only half that of its competitors. The company behind this model remains unclear, but there is widespread speculation in the industry that it may originate from a Chinese team, with some market observers guessing it could be from Alibaba's Tongyi Lab.
