Here’s a list of ControlNet models provided in the XLabs-AI/flux-controlnet-collections repository:

This project provides powerful ControlNet models for the Flux ecosystem, allowing users to control the image generation process more precisely, especially suitable for applications that require image generation based on edge detection or depth information.

InstantX Flux Union ControlNet

InstantX Flux Union ControlNet is a versatile ControlNet model designed for FLUX.1 development version. This model integrates multiple control modes, allowing users to control the image generation process more flexibly.

Main features:

1. Multiple control modes: Supports various control modes, including Canny edge detection, Tile, depth map, blur, pose control, etc.

2. High performance: Most control modes have achieved high effectiveness, especially Canny, Tile, depth map, blur, and pose control modes.

3. Continuous optimization: The development team is constantly improving the model to enhance its performance and stability.

4. Compatibility: Fully compatible with the FLUX.1 development version base model, easily integrating into existing FLUX workflows.

5. Multi-control inference: Supports the simultaneous use of multiple control modes, providing users with more fine-grained image generation control.

Usage:

1. Single control mode:

   • Load the Union ControlNet model
   • Select the desired control mode (e.g., Canny, depth map, etc.)
   • Set the control image and related parameters
   • Generate the image

2. Multi-control mode:

   • Load the Union ControlNet model as FluxMultiControlNetModel
   • Set different control images and parameters for each control mode
   • Apply multiple control modes simultaneously to generate the image

Notes:

• The current version is a beta version and may not be fully trained yet, so you may encounter some imperfections during use.
• Some control modes (such as grayscale control) may have lower effectiveness, so it’s recommended to prioritize high-effectiveness modes.
• Compared to specialized single-function ControlNet models, the Union model may perform slightly less well on certain specific tasks, but it offers greater flexibility and versatility.

Resource links:

• Model download: InstantX/FLUX.1-dev-Controlnet-Union-alpha

Note: After downloading the model, it’s recommended to rename the file to a more descriptive name, such as “flux_union_controlnet.safetensors”, for easier file management and identification in the future.

This Union ControlNet model provides a powerful and flexible image control tool for the FLUX ecosystem, especially suitable for users who need to implement multiple control functions in a single model. With continuous optimization and updates, it has the potential to become one of the most comprehensive and powerful ControlNet models on the FLUX platform.

InstantX Flux Canny ControlNet

In addition to the Union ControlNet model, InstantX also provides a ControlNet model specifically for Canny edge detection. This model focuses on using the Canny edge detection algorithm to control the image generation process, providing users with more precise edge control capabilities.

Main features:

1. Focus on Canny edge detection: This model is specifically optimized for Canny edge detection, allowing for better processing and utilization of edge information.

2. High-resolution training: The model was trained in a multi-scale environment with a total pixel count of 10241024, using a batch size of 88 for 30k steps.

3. Compatible with FLUX.1: Designed for the FLUX.1 development version, it can seamlessly integrate into FLUX workflows.

4. Uses bfloat16 precision: The model uses bfloat16 precision, which can improve computational efficiency while maintaining accuracy.

Usage:

1. Install the latest version of the Diffusers library.
2. Load the Flux Canny ControlNet model and FLUX.1 base model.
3. Prepare the input image and apply Canny edge detection.
4. Use the detected edges as control input to generate the image.
