What is CogVideoX?
The CogVideo/CogVideoX repository provides the code and models of the CogVideoX series of open-source video generation models. The series supports three tasks: text-to-video generation, video continuation, and image-to-video generation. CogVideoX1.5-5B supports higher-resolution 10-second videos, and the I2V model takes an image as a background input and combines it with a prompt to create a video. It also provides diffusers-based LoRA fine-tuning code and online demo spaces on Hugging Face and ModelScope.
