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 latest version introduces significant improvements including WFVAE (Waterfall VAE), prompt refiner, advanced data filtering, and sparse attention mechanisms. The model is capable of generating high-quality videos while being resource-efficient, supporting 93x480p resolution within 24GB VRAM.
Implementation Details
The model implements a sophisticated 3D attention architecture that replaces traditional 2+1D approaches. It utilizes CausalVideoVAE with high compression capabilities, able to compress videos by 256 times (4×8×8) while maintaining quality. The implementation includes a new sparse attention architecture for better spatiotemporal feature capture.
