Model Card
HappyHorse 1.1 Reference-to-Video is a video generation model from Alibaba, built by the company's ATH (Alibaba Token Hub) AI Innovation Unit. Its reference-to-video (R2V) mode takes 1 to 9 reference images of characters or scenes together with a text prompt and composes them into a single video, keeping each subject's identity consistent across shots.
HappyHorse is a 15-billion-parameter unified self-attention Transformer that generates video and audio in one pass rather than as separate steps. Version 1.0 first appeared anonymously in the Artificial Analysis Video Arena in April 2026 before Alibaba was named as its creator; version 1.1 followed in June 2026 with stronger motion expressiveness, tighter multi-image consistency, and improved audio-visual sync.
Output runs 3 to 15 seconds at 720p or 1080p across multiple aspect ratios.

Qwen Image 3
Qwen Image 3 is Alibaba's third-generation text-to-image model from the Qwen team, released in July 2026 as a closed model with no public weights. It accepts prompts of up to 4,500 tokens, so a multi-panel layout such as an infographic grid or a nested interface mockup can be generated in a single pass. It renders text natively in 12 languages, including legible text as small as ten pixels and mathematical formulas with subscripts and superscripts. It also produces photorealistic detail such as skin pores and individual hair strands, and supports image editing that matches the original style. Alibaba has not published benchmarks for this release. Its predecessor, Qwen Image 2.0, ranked just behind GPT Image 2 and Nano Banana Pro on Alibaba's arena platform. It suits developers building posters, infographics, multilingual product visuals, and storyboards where long prompts and accurate text matter.

On the Text-to-Image Arena leaderboard it debuted at #5 with a score of 1,263, up from Qwen Image 2.0 Pro at #15 with 1,191. It suits developers building posters, infographics, and multilingual design assets that need accurate text.
VideoHappyHorse 1.1 Text-to-Video
HappyHorse 1.1 Text-to-Video is a video generation model from Alibaba's ATH (Alibaba Token Hub) AI Innovation Unit, generating video and synchronized audio together in a single pass rather than adding sound afterward. It builds on HappyHorse 1.0, with Alibaba reporting improvements in motion dynamics, subject consistency, prompt adherence, visual quality, and audio generation. The model outputs clips from 3 to 15 seconds at 720p or 1080p, in 16:9, 9:16, 1:1, 4:3, or 3:4 aspect ratios, with lip-synced dialogue, ambient sound, and effects generated alongside the visuals. Following its release in June 2026, it ranked No. 2 across Artificial Analysis's Video Arena leaderboards, behind Google's Veo 3.1.
