New analysis: Alibaba’s HappyHorse topped the AI video leaderboard last week. The timing matters more than the score. It appeared during peak customer frustration with Bytedance’s pricing. Alibaba Cloud sales teams were already approaching Volcano Engine’s enterprise clients.

HappyHorse 1.0是阿里巴巴的旗艦AI影片模型,截至2026年4月在Artificial Analysis排行榜上排名第一。它基於單流Transformer架構,約150億參數,在統一管線中實現業界領先的運動穩定性、提示遵循能力和視覺保真度。
HappyHorse提供5個端點,涵蓋完整的創作流程:文字生影片、圖像生影片、參考生影片(基於主體或風格參考)、提示詞驅動的影片編輯,以及影片續寫。所有端點均支援720p和1080p輸出,時長可在3到15秒之間。
生成的片段時長可從3秒到15秒,預設為5秒。定價按時長線性計算,因此在相同解析度下,10秒片段的費用正好是5秒片段的兩倍。
HappyHorse支援五種長寬比:16:9(橫屏)、9:16(直屏)、1:1(正方形)、4:3(經典橫屏)和3:4(經典直屏)。開箱即用地涵蓋電影、社交和傳統格式。
HappyHorse採用直觀的按秒計費:720p每秒20積分,1080p每秒35積分。總費用等於每秒積分乘以時長。例如,5秒720p片段需100積分,5秒1080p片段需175積分。
截至2026年4月,HappyHorse 1.0在Artificial Analysis排行榜的文字生影片和圖像生影片兩項中均排名第一,領先於Seedance 2.0和Wan 2.7。其單流Transformer架構在運動穩定性和提示遵循方面相比雙分支和MoE風格的競品表現尤為突出。
