What is HappyHorse 1.0?

HappyHorse 1.0 is a 15-billion-parameter AI video generation model built by Alibaba's Taotian Future Life Lab. The model debuted in April 2026 and went straight to #1 on the Artificial Analysis Video Arena for both text-to-video (Elo 1333) and image-to-video (Elo 1392), ranked by blind human preference votes. Architecturally, it's a unified 40-layer self-attention Transformer that processes text, image, video, and audio tokens in a single sequence - which is why one forward pass produces a 1080p clip with synchronized dialogue, ambient sound, and Foley. It's now live on invideo alongside Kling 3.0, and Seedance 2.0.

How does HappyHorse compare to Sora 2, Veo 3.1, Kling 3, and Seedance 2.0?

On the Artificial Analysis Video Arena (blind human preference, no audio), HappyHorse 1.0 currently leads both text-to-video and image-to-video, with Sora 2, Veo 3.1, Kling 3, and Seedance 2.0 ranked below. Beyond rankings: Happy Horse generates audio in the same pass as the video (most competitors use a separate audio model); it offers four input modes including up to 9 image references and V2V editing (most offer text plus a single image); and lip-sync runs natively in 7 languages without a dubbing pass. Sora 2 still has unique strengths in long-form physics, Veo 3.1 in certain photorealistic looks, and Kling 3 in stylized aesthetics - invideo carries all of them so you can match the model to the shot.

What aspect ratios and clip lengths does HappyHorse 1.0 support?

HappyHorse 1.0 outputs in 16:9, 9:16, 1:1, 4:5, 4:3, 3:4, and 21:9 - covering YouTube, TikTok, Instagram Reels, Shorts, Facebook, LinkedIn, and broadcast formats. Resolution options run from 720p to 1080p. Maximum clip length per single generation is 15 seconds.

Which languages does HappyHorse 1.0 support for lip-sync?

Native lip-sync runs in seven languages: English, Mandarin, Cantonese, Japanese, Korean, German, and French. Happy horse 1.0 model achieves industry-leading low Word Error Rate, which means generated mouth shapes match the spoken words closely enough to ship dialogue scenes without a second dubbing pass.

How long does each HappyHorse generation take?

About 38 seconds for a 1080p clip, a roughly 5x speed advantage over typical diffusion-based competitors. The speed comes from DMD-2 distillation, which cuts denoising to just 8 steps.

Does HappyHorse AI work on mobile?

Yes. invideo runs natively on iOS and Android, and Happy Horse 1.0 generation is fully supported on mobile - you can prompt, upload reference images, generate, preview, and export from your phone. The mobile experience is optimized for vertical 9:16 generation, which is the dominant format for TikTok, Reels, and Shorts.

Can I use videos generated with HappyHorse commercially?

Yes. Videos generated on any invideo come with commercial usage rights. Paid ads, product launches, social campaigns, client work, monetized YouTube channels, and any other revenue-generating use case are all covered. Two things to verify before publishing: (1) any input assets you use must be assets you have rights to, and (2) some platforms (TikTok, Meta) and jurisdictions (EU AI Act) now require AI-generated content to be disclosed.
