## What it is
CogVideo/CogVideoX is an open-source family of text-to-video and image-to-video generation models from Zhipu AI (THUDM), with inference and fine-tuning code in Python. It includes model weights on Hugging Face, diffusers integration, LoRA fine-tuning, and demo tooling.

## Use cases
- generate videos from a text prompt
- convert an image into a short video
- fine-tune a video generation model on custom data
- run text-to-video inference on a local GPU
- compare open-source alternatives to Sora
- build an app that animates still images

## When to choose
- you need open weights for text-to-video or image-to-video generation
- you want to fine-tune a video diffusion model with LoRA on consumer GPUs
- you want diffusers-compatible video generation models

## When to avoid
- you need commercial-grade, hosted video generation without managing GPUs
- you only need image generation, not video
- you lack a capable GPU for inference or training

## Facets
- artifact type: library
- maturity: active
- function: machine-learning, deep-learning, video-processing, image-processing, llm-inference, llm-training
- domain: artificial-intelligence, deep-learning, image-processing, machine-learning
- platform: python
- tags: text-to-video, image-to-video, video-generation, diffusion-models, cogvideox, sora, model-weights, diffusers, video, gpu, linux
