As of 12:00 PM on April 10, 2026, it was unclear which AI research institution developed HappyHorse-1.0, and it was also completely unknown whether HappyHorse-1.0 was its official name or a codename.

Then, shortly after 1:00 PM on April 10, 2026, information on Artificial Analysis was updated, revealing that HappyHorse-1.0 was developed by Alibaba-ATH, Alibaba's AI division. However, Alibaba-ATH includes multiple AI research teams, including Tongyi Lab, which developed the Wan series of video generation AI, and it is unclear which research team developed Artificial Analysis.



The official X page for Artificial Analysis also highlights that HappyHorse-1.0 was developed by Alibaba Group. It also mentions that the API service will launch on April 30, 2026.




Additionally, Alibaba Group's official X account provides a link to another X account called HappyHorse (@HappyHorseATH) .




HappyHorse (@HappyHorseATH) has posted only one message, explicitly stating that they are part of Alibaba-ATH. At the same time, they state, 'We have not yet launched an official website. The website you have seen is not ours,' warning people not to access fake sites.




If you actually search for the phrase 'HappyHorse-1.0' on Google, you will find several websites that look like the official HappyHorse website. These sites have registration buttons for video generation services, but they are unrelated to HappyHorse, so please do not enter any personal information on them.
