What is Open-Sora-Plan-v1.3.0?
Open-Sora-Plan v1.3.0 is an ambitious open-source project aimed at recreating OpenAI's Sora capabilities. This version introduces significant improvements including WFVAE (Waterfall VAE), prompt refiner, and innovative data filtering strategies. The model can generate high-quality videos with dimensions up to 93x480p using just 24GB of VRAM.
Implementation Details
The model implements a sophisticated 3D attention architecture, moving beyond the traditional 2+1D approach. It features a high-performance CausalVideoVAE capable of compressing videos by 256 times (4×8×8) while maintaining quality. The architecture employs sparse attention mechanisms for efficient processing of spatial-temporal information.
- 3D full attention architecture for better spatiotemporal feature capture
