  ## 🚀 Why Helios? (Compared to SVD, Sora, AnimateDiff, etc.)
  
  Helios offers a unique combination of real-time performance, minute-scale high-quality output, and efficiency for long video generation. Unlike many alternatives, it achieves this without relying on conventional anti-drifting strategies or standard video acceleration techniques, making it faster and more coherent for extended sequences.
