How can I optimize the efficiency of parameter configuration for ComfyUI workflows?

Background

Parameter debugging accounts for 70% of the time cost of AI workflow development, and traditional manual tuning is inefficient and experience-dependent.ComfyUI-Copilot's automated parameter optimization feature can significantly improve this pain point.

Core Solutions

• One-click optimization: After the workflow has run, click the "Optimize" button on the Copilot screen and the system will automatically adjust the following parameters based on the current output quality:
  • Sampler type (DPM++ 2M Karras recommended)
  • CFG scale value (Intelligent fit for 7-12 range)
  • Denoising intensity (dynamically calculated based on resolution)
• comparison experiment: Using the "compare [parameter_name]" command (e.g. "compare sampler"), Copilot generates a test grid with different combinations of parameters.
• History Learning: The system records the parameter combinations of successful workflows and automatically recommends the historically optimal configuration when similar tasks are detected.

practical skill

• For image generation, set a lower number of steps (15-20 steps) for parameter roughing, and then increase the number of steps for fine-tuning after determining the direction.
• Use the "explain parameters" command to get the technical description and recommended range for each parameter.
• When batch processing, establish the parameter change rules (e.g. "CFG from 7 to 10, step size 0.5″) by "set batch parameters" command.

Summary points

Copilot's parameter optimization system can reduce 4-6 rounds of manual debugging on average, and it is recommended to focus on the optimization of three core parameters: sampler, CFG, and denoise. Note that different models require different optimization strategies, you can use "query model profile" to understand the model characteristics.
