A mysterious AI video model that has ascended global leaderboards has been confirmed as a project from Chinese tech giant Alibaba, in a development that could boost the company’s artificial intelligence ambitions.
HappyHorse-1.0, which appeared on the benchmarking platform Artificial Analysis around April 7, without identifying its affiliations, climbed to the top of blind-test rankings for both text-to-video and image-to-video generation.
The developers revealed in a newly created X account Friday that HappyHorse was part of Alibaba’s ATH AI Innovation Unit and that the project was still under development. Alibaba confirmed to CNBC that the post was genuine.
The anonymous debut of the model had sparked online speculation about whether the developer was a tech giant such as Tencent or Alibaba or an independent developer.
The Hong Kong-listed shares of Alibaba closed 2.12% higher Friday after news of its involvement. Its stock rose 6.75% on Wednesday, lifted by a broader rally in technology stocks after U.S.-Iran tensions eased, alongside speculation that Alibaba was behind the mysterious model.
Alibaba has raced to expand its AI offerings amid intense competition in China, building on its flagship Qwen large language model and chatbot app.
While previous AI model series from Alibaba have included dedicated video generation capabilities, none have generated the same level of buzz or ranked as highly as Happy Horse has in just a matter of days.
HappyHorse-1.0 could strengthen Alibaba’s position in video generation, an area where competitors have faced setbacks.
OpenAI recently discontinued its Sora video generation app and platform, citing a strategic shift to focus on coding tools, corporate clients and AGI development amid high compute costs.
While OpenAI’s exit could cede more ground to Chinese competitors, ByteDance was recently forced to pause the rollout of its viral Seedance 2.0 following copyright disputes with major Hollywood studios and streaming platforms.
Alibaba Chief Executive Officer Eddie Wu has made AI development the overriding priority for the tech giant’s sprawling business, which also includes chip design and data centers.
Alibaba has previously integrated its AI models into its other e-commerce, advertising and entertainment products, and could be aiming to do the same with Happyhorse.
