Alibaba launches HappyHorse‑1.0

A text prompt is the written instruction you give an artificial intelligence model, and a text-to-video model turns that instruction into moving images the way an image generator turns a sentence into a picture. An image-to-video model starts with a still image and then animates it into a short clip instead of inventing every frame from scratch. (artificialanalysis.ai) That field has turned into a speed race between cloud companies because video generation is expensive to run and businesses want it inside the same platform where they already buy computing power. Alibaba Cloud already sells video generation through its Model Studio service, which lists text-to-video, image-to-video, reference-to-video, video editing, lip-syncing, and character-swapping tools in one enterprise product catalog. (alibabacloud.com, alibabacloud.com) Alibaba has now confirmed that the mysterious model called HappyHorse-1.0 belongs to Alibaba, after it appeared on public rankings without a clear owner around April 7 and then jumped to the top within days. CNBC reported on April 10 that the model led blind-test rankings for both text-to-video and image-to-video generation before Alibaba acknowledged it was behind it. (cnbc.com, technode.com) Those rankings come from Artificial Analysis, which runs a “Video Arena” where models are compared through human preference votes instead of company marketing demos. On April 10, the site showed HappyHorse-1.0 at 1,355 Elo in text-to-video, ahead of ByteDance’s Dreamina Seedance 2.0 at 1,273 and ahead of Google Veo 3 at 1,221. (artificialanalysis.ai) The reveal also answered who inside Alibaba built it. TechNode reported on April 10 that Alibaba said HappyHorse was developed by the AI Innovation Unit under its ATH subsidiary and that the model was in internal testing with application programming interface access coming soon. (technode.com) That “application programming interface” is the software doorway companies use to plug a model into their own apps, ad tools, or editing systems without waiting for a consumer app. CNBC reported that Alibaba plans to offer HappyHorse through Alibaba Cloud for enterprise customers, which points to the cloud business as the main distribution channel. (cnbc.com) Alibaba has been building toward this for more than a year. In September 2024, Alibaba Cloud announced a new text-to-video model as part of a broader push around Qwen and cloud infrastructure, and by March 23, 2026, its documentation showed a mature menu of enterprise video tools rather than a single demo model. (alibabacloud.com, alibabacloud.com) Alibaba’s older Wan line is still in the market too, which makes HappyHorse look less like a one-off experiment and more like a second serious bet. Artificial Analysis still lists Alibaba Wan 2.6 on the same leaderboard, while Alibaba Cloud published a new Wan2.7-Video announcement on April 7, 2026, just days before HappyHorse was unmasked. (artificialanalysis.ai, alibabacloud.com) What changes now is who gets the tool first. A cloud-first rollout means advertising agencies, e-commerce teams, game studios, and media companies can buy generation capacity as a business service, which is usually faster to monetize than building a mass-market video app from zero. (alibabacloud.com, cnbc.com) It also puts more pressure on the rest of the leaderboard. On April 10, Artificial Analysis showed a market where ByteDance, Google, OpenAI, Runway, Kling, PixVerse, and Alibaba were all packed into the same table, and HappyHorse moved Alibaba from being one strong entry among many to the model at the top of the board.
