🇹🇼 Alibaba Happy Horse AI 影片模型解析:匿名空降排行榜第一,15B 參數打趴 Seedance 2.0,1080p 影片還自帶音效

Alibaba Happy Horse 是阿里巴巴在 2026 年 4 月匿名發布的 AI 影片生成模型,上線即空降 Artificial Analysis 影片排行榜第一名,打敗字節跳動的 Seedance 2.0。更戲劇化的是——沒人知道它是誰做的,直到阿里巴巴自己出來認領。就在 OpenAI 宣布關閉 Sora 的同時,中國這邊悄悄端出了一匹黑馬。

Happy Horse AI 是什麼?為什麼突然爆紅?

Happy Horse 1.0 是一個 150 億參數的開源 AI 影片生成模型,能從文字或圖片生成 1080p 影片,而且自帶同步音效。它用匿名身份上架排行榜,直接衝到第一名,引發整個 AI 圈猜測「這到底是誰做的?」最後阿里巴巴在 4 月 10 日揭曉身份,確認是旗下 Token Hub 創新事業部的作品。

Happy Horse 的技術規格有多強?

Happy Horse 1.0 的架構在同級模型中相當獨特:

  • 150 億參數,開源釋出
  • 40 層 Self-Attention Transformer:用統一架構同時處理影片和音訊
  • 文字轉影片 + 圖片轉影片:兩種模式都排名第一
  • 1080p 解析度:目前影片 AI 的頂規標準
  • 同步音效生成:一條管線搞定影音,不需要後製配音

在 Artificial Analysis Video Arena 排行榜上,Happy Horse 同時拿下文字轉影片和圖片轉影片的雙料冠軍,把字節跳動的 Seedance 2.0 擠到第二。

Happy Horse 和 Sora 比起來怎樣?

很諷刺的是,Happy Horse 爆紅的時間點剛好撞上 OpenAI 宣布關閉 Sora。Sora 燒了每天 1500 萬美元的算力成本,用戶從百萬跌到不到 50 萬,連迪士尼 10 億美元的合作案都因此告吹。而 Happy Horse 用 150 億參數就做到排行榜第一,還是開源免費的。AI 影片生成的王座,正在從美國轉向中國。

開發者現在可以用 Happy Horse 嗎?

目前 Happy Horse 還在 beta 測試階段,但阿里巴巴已經預告「近期」會開放 API 存取。模型本身是開源的,技術能力強的開發者現在就可以自己部署。對於想做影片 AI 應用但不想被 API 價格綁架的團隊,這是一個值得關注的選項。

不過話說回來,排行榜第一不代表實際使用一定好。匿名發布衝榜這招雖然行銷效果滿分,但真正的考驗是開放 API 後的穩定度和實際使用體驗——好不好用,試了才知道。


🇺🇸 Alibaba Happy Horse AI Video Model: Anonymous #1 Debut Beats Seedance 2.0 With 15B Params and Built-in Audio

Alibaba's Happy Horse is an AI video generation model that debuted anonymously in April 2026 and immediately claimed the #1 spot on the Artificial Analysis Video Arena leaderboard, beating ByteDance's Seedance 2.0. The dramatic reveal — nobody knew who made it until Alibaba claimed ownership on April 10 — coincided with OpenAI's announcement that it was shutting down Sora.

What Is Happy Horse AI and Why Did It Go Viral?

Happy Horse 1.0 is a 15-billion-parameter open-source AI video generation model that creates 1080p videos with synchronized audio from text or image prompts. It was submitted anonymously to benchmark leaderboards and shot straight to #1, sparking intense speculation across the AI community. Alibaba's Token Hub innovation unit eventually confirmed it as their creation.

What Are Happy Horse's Technical Specs?

The architecture stands out among current video AI models:

  • 15 billion parameters, fully open-source
  • 40-layer unified self-attention Transformer: processes video and audio jointly
  • Text-to-video and image-to-video: ranked #1 in both categories
  • 1080p resolution: current top-tier standard for video AI
  • Synchronized audio generation: single pipeline for both video and sound

On the Artificial Analysis Video Arena, Happy Horse topped both text-to-video and image-to-video rankings, pushing ByteDance's Seedance 2.0 to second place.

How Does Happy Horse Compare to Sora?

The timing is striking. Happy Horse went viral just as OpenAI announced Sora's shutdown. Sora was burning an estimated $15 million per day in compute costs, saw users drop from 1 million to under 500,000, and lost a $1 billion Disney partnership. Meanwhile, Happy Horse achieved #1 rankings with just 15B parameters and an open-source license. The AI video generation crown appears to be shifting from the US to China.

Can Developers Use Happy Horse Now?

Happy Horse is currently in beta testing, but Alibaba has announced API access is coming "in the near future." The model itself is open-source, so developers with sufficient compute can self-deploy now. For teams building video AI applications without wanting to be locked into expensive API pricing, this is worth watching.

That said, leaderboard rankings don't always translate to real-world reliability. The anonymous debut was brilliant marketing, but the real test will be stability and user experience once the API goes live.
