Part 2. Details of HappyHorse 1.0 vs. Seedance 2.0 in Video Arena
As of mid-April 2026, HappyHorse 1.0 (Alibaba) has taken over as the top AI video model in the Artificial Analysis Video Arena and leads in visual quality (text-to-video and image-to-video) without audio. Seedance 2.0 (ByteDance) is a great choice for multi-modal and sound-integrated video generation.
Artificial Analysis follows a blind user vote system where you see two videos generated using two different models from the same text prompt or image, and you have to choose the one you find accurate without knowing which model created which video. The models are then ranked using an Elo system where the winner gains Elo points and the loser loses some. A higher Elo score means that the particular model is preferred/voted highly by users.
