About THUDM/CogVideo

THUDM/CogVideo is an open-source repository for the CogVideo (ICLR 2023) and CogVideoX series models for text-to-video and image-to-video generation. It includes inference and fine-tuning code using SAT and Diffusers implementations, plus tools for LoRA fine-tuning, DDIM Inverse, prompt optimization, and video captioning with CogVLM2-Caption. The CogVideoX series also supports video continuation.

Online demos are listed for Hugging Face Space and ModelScope Space. Local use requires compatible GPUs, such as GTX 1080TI-class hardware for CogVideoX-2B and RTX 3060-class hardware for CogVideoX-5B, with specific dependency setup.
