Pros
  • Huge zoo of generative and restoration models in one consistent codebase
  • Strong evaluation and benchmarking tooling for research workflows
  • Open source under OpenMMLab with active GitHub project
  • Covers both image and video tasks, including frame interpolation
  • Fully open weights
  • Run locally
  • Massive ecosystem (LoRAs, ControlNet)
  • Fine-tunable for custom domains
Cons
  • No hosted product or UI; requires PyTorch and a GPU
  • OpenMMLab config system has a steep learning curve
  • Diffusion community has largely moved to diffusers and ComfyUI
  • Some submodules lag behind upstream model releases
  • Setup is technical
  • Default quality below Midjourney
