With fal you have the option to pick between 720p or 1080p resolution and it supports formats like 16:9, 9:16, 1:1, 4:3, 3:4 to ensure your content fits various social platforms. fal also guarantees full commercial rights for all generated outputs. fal's lightning inference speed is optimized with the latest AI infrastructure technology, making it one of the fastest ways to generate content via the HappyHorse-1.0 API. Official Happy Horse API EndpointsYou can access the official API via fal with 4 API endpoints. You can get an API key from the API Keys page in your dashboard at fal.ai:<ul type="disc"> <li>https://fal.ai/models/alibaba/happy-horse/image-to-video</li> <li>https://fal.ai/models/alibaba/happy-horse/reference-to-video</li> <li>https://fal.ai/models/alibaba/happy-horse/text-to-video</li> <li>https://fal.ai/models/alibaba/happy-horse/video-edit</li> </ul>About HappyHorse-1.0HappyHorse-1.0, built by Alibaba's Taotian Future Life Lab under the Alibaba Token Hub division, is the first video model to reach the top of the Artificial Analysis leaderboard rankings based on blind human preference votes: users compare two unlabeled clips and pick the better one, with no knowledge of which model produced either. The model earned an Elo of 1333 in Text-to-Video and 1392 in Image-to-Video (no audio), placing it above every other video generation model currently benchmarked.HappyHorse-1.0 was led by Zhang Di, a 15-year AI industry veteran who previously served as VP at Kuaishou and technical architect of Kling AI, before rejoining Alibaba in late 2025. A fal spokesperson noted that &#34;HappyHorse is known for producing 1080p video with synced audio, strong lighting, and realistic, emotional, and consistent detail.&#34;The model's core architecture is a unified 40-layer self-attention Transformer that generates video and audio jointly in a single forward pass, with no cross-attention modules and no separate audio post-processing step. The result is synchronized audiovisual output with native lip-sync support across seven languages: English, Mandarin, Cantonese, Japanese, Korean, German, and French. The team claims approximately 38-second generation time for 1080p output on a single NVIDIA H100 GPU.Happy Horse Use CasesThe model supports use cases ranging from product promos and social content to multi-shot sequences with consistent character identity across frames. Camera direction fidelity, including cues like &#34;slow dolly push-in,&#34; &#34;overhead crane shot,&#34; and &#34;breeze versus strong wind,&#34; are some examples of key differentiators for developers building video production workflows.
