The Zhang Di Connection
The story of HappyHorse vs Kling is fundamentally a story about Zhang Di (张迪). As VP of Kuaishou, Zhang Di led the development of the original Kling video model, which was one of the most prominent AI video generators in China.
At Alibaba, Zhang Di built HappyHorse 1.0 from the ground up. The model first appeared anonymously on the Artificial Analysis Video Arena on April 7, 2026, and quickly surpassed Kling 3.0 in the rankings. This talent migration represents a significant shift in China's AI video landscape.
Key Differences
1. Unified Audio Generation
HappyHorse 1.0 generates video and audio together in a single unified pass — sound effects, music, and dialogue are naturally synchronized to the visual content. Kling 3.0 generates video only, requiring separate tools for audio.
2. Multi-Shot Storytelling
HappyHorse can maintain character identity across multiple shots for coherent narrative videos. Kling 3.0 does not offer this capability, limiting it to single-shot generation.
3. Availability
Kling 3.0 is publicly available through Kling.ai with API access. HappyHorse 1.0 is not yet publicly available as of April 2026.
Final Verdict
HappyHorse 1.0 is the stronger choice for those seeking the absolute highest quality and unified audio-video generation. However, for creators who need a tool today, Kling 3.0 remains the practical choice with its established ecosystem and public availability.
