AIbase Report (April 8, 2026) — The AI video generation field has once again witnessed a major surprise. Yesterday, the authoritative AI evaluation platform Artificial Analysis suddenly introduced a new unknown model "Happy Horse" (with V1 and V2 versions) on the AI Video Arena leaderboard. As soon as the model was launched, it strongly surpassed the previously leading Seedance2.0, quickly taking the top spot and sparking heated discussions within the global AI community.

The Mysterious Model Rises Strongly, Leading in Performance

According to the latest data from Artificial Analysis, Happy Horse has comprehensively outperformed Seedance2.0 in multiple core indicators, including text-to-video, especially excelling in image consistency, detail accuracy, and motion naturalness. More surprisingly, the model supports audio generation natively, allowing for realistic sound output, achieving true multimodal video creation capabilities.

Early community test examples show that Happy Horse can easily handle complex dynamic scenes, such as a long-time video showing "flowers in the same vase blooming and withering over two weeks" with coherent visuals and realistic lighting, far exceeding the usual performance of similar models. Currently, Happy Horse is firmly at the top of the leaderboard, with some test results indicating its comprehensive score has already taken a lead over Seedance2.0.

Origin Remains a Mystery, Possibly an Asian Cutting-Edge Technology

As of the time of this report, the developers of Happy Horse have not yet revealed their identity, and no official statements have been released. However, based on the generation style and rapid iteration speed, industry experts generally speculate that it may come from an Asian AI laboratory (likely related to a Chinese team). Some analysts believe it could be a major upgrade of the WAN series video models or a secret weapon of an undisclosed laboratory.

Compared to Seedance2.0, Happy Horse shows clear advantages in long video stability, prompt following accuracy, and audio synchronization, earning it the nickname "potential Seedance killer" among many developers. The emergence of this mysterious underdog once again proves that competition in the AI video generation field has entered a feverish stage.

Significant Industry Impact, the New Era of AI Video May Accelerate

Seedance2.0 was previously hailed as a top performer in the AI video generation field, and the sudden rise of Happy Horse marks the beginning of a new round of technological iteration in this area. Artificial Analysis, by promptly introducing an unknown model, has further solidified its authority in the AI evaluation field.

AIbase editors will continue to follow the subsequent developments of Happy Horse, including whether the model will open public testing, the revelation of the developer's identity, and more real-generation cases. Once there are new updates, we will provide in-depth analysis and comparison tests immediately.

The next revolution in AI video generation may have already quietly begun. Do you think Happy Horse will become the next industry benchmark? Please share your views in the comments section!
