ComfyDeploy: How FreeU_Advanced works in ComfyUI?

What is FreeU_Advanced?

This custom node provides advanced settings for FreeU.

How to install it in ComfyDeploy?

Head over to the machine page

  1. Click on the "Create a new machine" button
  2. Select the Edit build steps
  3. Add a new step -> Custom Node
  4. Search for FreeU_Advanced and select it
  5. Close the build step dialig and then click on the "Save" button to rebuild the machine

FreeU Advanced Plus

Let's say you and I grab dinner, and movie after lunch? 🌃📺😏

Input Parameters

  • model (MODEL): Model to patch
  • target_block (COMBO): Which block to target; input_block, middle_block, and output_block
  • multiscale_mode (COMBO): A list of available multiscale modes:
    • ["Default", "Bandpass", "Low-Pass", "High-Pass", "Pass-Through", "Gaussian-Blur", "Edge-Enhancement", "Sharpen", "Multi-Bandpass", "Multi-Low-Pass", "Multi-High-Pass", "Multi-Pass-Through", "Multi-Gaussian-Blur", "Multi-Edge-Enhancement", "Multi-Sharpen"]
  • multiscale_strength (FLOAT, Default: 1.0, Range: [0.0, 1.0], Step: 0.001): Strength of scaling
  • b1_slice (INT, Default: 640, Range: [64, 1280], Step: 1): The size of the array slice for b1 operation
  • b2_slice (INT, Default: 640, Range: [64, 640], Step: 1): The size of the array slice for b2 operation
  • b1 (FLOAT, Default: 1.1, Range: [0.0, 10.0], Step: 0.001): b1 output multiplier
  • b2 (FLOAT, Default: 1.2, Range: [0.0, 10.0], Step: 0.001): b2 output multiplier
  • s1 (FLOAT, Default: 0.9, Range: [0.0, 10.0], Step: 0.001): s1 Fourier transform scale strength
  • s2 (FLOAT, Default: 0.2, Range: [0.0, 10.0], Step: 0.001): s2 Fourier transform scale strength

Optional Parameters

  • b1_mode (COMBO): Blending modes for b1 multiplied result.
    • ['bislerp', 'colorize', 'cosine interp', 'cuberp', 'hslerp', 'inject', 'lerp', 'linear dodge', 'slerp']
  • b1_blend (FLOAT, Default: 1.0, Range: [0.0, 100], Step: 0.001): Blending strength for b1.
  • b2_mode (COMBO): Blending modes for b2 multiplied result.
    • ['bislerp', 'colorize', 'cosine interp', 'cuberp', 'hslerp', 'inject', 'lerp', 'linear dodge', 'slerp']
  • b2_blend (FLOAT, Default: 1.0, Range: [0.0, 100], Step: 0.001): Blending strength for b2.
  • threshold (INT, Default: 1.0, Range: [1, 10], Step: 1): The exposed threshold value of the Fourier transform function.
  • use_override_scales (COMBO): "true", or "false" on whether to use override_scales
  • override_scales (STRING, Default: [Multiline String]): Override scales. Create custom scales and experiment with results.
    • Example 10, 1.5 would create the multiscale_mode effect Sharpen
    • You can use #, // and ! to comment out lines.
