This repository provides a curated collection of Google Colab notebooks designed to simplify the setup and usage of ComfyUI, a powerful node-based graphical user interface for Stable Diffusion. It targets users who want to leverage various Stable Diffusion models and ControlNet features without complex local installations, offering pre-configured environments for quick experimentation.

How It Works

The project offers a series of Colab notebooks, each pre-configured with specific ComfyUI versions, model checkpoints, and extensions. This approach eliminates the need for manual dependency management and hardware configuration, allowing users to immediately start generating images. The notebooks are structured to support a wide array of popular Stable Diffusion models, including specialized ones for anime, photorealism, and specific artistic styles, along with ControlNet preprocessors for advanced conditioning.

Quick Start & Requirements

• Install/Run: Open and run the desired ComfyUI Colab notebook directly in Google Colab.
• Prerequisites: A Google account is required to use Google Colab. GPU acceleration is automatically enabled within the Colab environment.
• Resources: Colab provides free GPU access, but usage limits may apply. Notebooks may download large model files.

Highlighted Details

• Extensive support for numerous Stable Diffusion models (e.g., Stable Diffusion v1.4, v2.1, Waifu Diffusion, Anything V3, DreamShaper).
• Integration of ControlNet and its associated preprocessors for advanced image generation control.
• Categorization of notebooks into "lite," "stable," and "nightly" builds, offering different feature sets and update frequencies.
• Includes specific notebooks for specialized models and techniques like inpainting and depth-to-image.

Maintenance & Community

• The project is actively maintained by "camenduru," with community suggestions and contributions acknowledged.
• Links to Twitter and Discord are provided for updates and community interaction.

Licensing & Compatibility

• The licensing of individual models used within the notebooks varies and is inherited from their respective Hugging Face pages. ComfyUI itself is typically under an MIT license.
• Compatibility for commercial use depends on the licenses of the underlying Stable Diffusion models and extensions.

Limitations & Caveats

The project relies on Google Colab's infrastructure, which may have usage limitations or changes. The "nightly" builds might be less stable due to frequent updates. Users should verify the licenses of specific models for commercial use.
