HappyHorse 1.1 Goes Global: Full API on Model Studio, Video Editing, and a Climb Past Seedance

Alibaba Cloud has opened HappyHorse 1.1's complete capability set via API on Model Studio — the 快乐马 line's biggest step since it topped the arena at 1.0: a new video-editing mode, integrated audio at no extra cost, a 40% two-week launch discount — and a No. 2 global video-arena rank, ahead of Seedance and Sora.

Direct answer

HappyHorse 1.1 is officially live via API on Alibaba Cloud Model Studio (VentureBeat; Model Studio docs), with four generation modes — text-to-video, image-to-video, subject/reference-to-video, and the new video editing — plus integrated audio at no additional cost. It costs $0.0988/s at 720p and $0.1278/s at 1080p per the OpenRouter listing (served by Alibaba Cloud International), before the 40% sitewide launch discount running two weeks.

What shipped, per official and platform sources

  • Full API on Model Studio, globally. Alibaba Cloud's announcement (carried by its official channels and VentureBeat) puts all 1.1 capabilities behind the standard Model Studio API for enterprise and developer use — the "globally available" moment for the line.
  • A fourth mode: video editing. 1.0 shipped T2V / I2V / reference-to-video; 1.1 adds editing, which VentureBeat frames as covering "the full spectrum of commercial video needs from ideation through production to post-production."
  • Integrated audio at no extra cost — one pass, one price, native audio-video.
  • Platform roll call, day one: OpenRouter (alibaba/happyhorse-1.1, served by Alibaba Cloud International), Together AI (I2V endpoint), WaveSpeedAI (including a video-extend variant), and getimg.ai (1.1 alongside 1.0, commercial rights included).
  • The ranking story. Per VentureBeat's arena coverage, HappyHorse rises to No. 2 globally as "OpenAI's Sora and ByteDance's Seedance fall away," with Veo 3.1 as the remaining Western rival — and Alibaba's data suggesting HappyHorse outperforms Veo on user-perceived quality.
