A K-pop performer with long silver hair in a glossy pink-and-silver mini-dress, mid-dance on a neon-lit stage. Camera tracks slightly upward as she lands a pose, stage lights flare in the background, slow-motion at the beat drop, vertical 9:16 frame.
A man in a mustard-yellow t-shirt sprints away from camera down a long, brightly-lit modern hotel corridor. Handheld camera follows just behind in a single take, motion blur on the walls, warm overhead lighting, urgent breathing audio. 16:9, 6 seconds.

Happy Horse 1.0 is an open-source AI video generation model from Alibaba's Taotian Future Life Lab (led by Zhang Di, former Kuaishou Kling head). It is a 15-billion parameter model that jointly generates video and synchronized audio in a single pass, released April 2026.
As of April 2026, Happy Horse 1.0 topped the Artificial Analysis benchmark with Elo 1333 on text-to-video (115 points ahead of Seedance 2.0) and Elo 1392 on image-to-video. It is the highest-ranked open-source video model on independent third-party benchmarks.
Happy Horse 1.0 was developed by Alibaba's Taotian Future Life Lab — Alibaba's e-commerce algorithm hub, led by Zhang Di who previously led Kuaishou's Kling AI video team. The lab joined Alibaba at the end of 2025.
Seven languages: English, Mandarin Chinese, Cantonese, Japanese, Korean, German, and French. The model generates lip-synced dialogue plus ambient soundscapes in the same pass as the video.
Happy Horse generates synchronized video + audio in one pass (Seedance generates video only). On the Artificial Analysis text-to-video benchmark, Happy Horse leads Seedance 2.0 by 115 Elo points. Seedance has a longer track record and a larger creator-prompt library; Happy Horse is newer with stronger raw quality and audio capability.
Both are open-source 2026 releases with audio + video joint generation. LTX 2.3 targets 4K resolution and 50fps; Happy Horse targets up to 1080p with stronger benchmark ranking. LTX has up to 20-second clips; Happy Horse caps at 15 seconds. Both support commercial use under permissive licenses.
Open PromeAI's image-to-video workspace, pick 'Happy Horse 1.0' in the model dropdown, set aspect ratio + duration (up to 15s) + resolution (up to 1080p), write a prompt — include dialogue in your target language if you want lip-synced audio, and click Create.
Alibaba has promised a complete open-source release including base model, distilled model, super-resolution module, and inference code under a commercial-friendly license. The PromeAI integration provides hosted access without requiring you to self-host.
