FastVideo: a lightweight framework for accelerating large video diffusion models
FastVideo is an open-source framework for accelerating large video diffusion model. - hao-ai-lab/FastVideo
Scalable training with FSDP, sequence parallelism, and selective activation checkpointing, with near linear scaling to 64 GPUs. Fast-Hunyuan comparison with original Hunyuan, achieving an 8X diffusion speed boost with the FastVideo framework. We did not find significant improvement using multi-phase distillation, so we keep the one phase setup similar to the original latent consistency model's recipe.
