Efficency-nodes Extend Guide: Simplify Your AI Image Workflows
This image was created using ComfyUI on the Cephalon AI platform.

ComfyUI is flexible but gets cluttered with repetitive node connections. The Efficiency-nodes extension fixes this by packing multiple functions into 2 core node types (loaders + samplers), cutting workflow complexity and saving time. It also adds features like HD restoration and XY parameter comparison charts.

Key Nodes in Efficiency-nodes

Efficiency Loaders
  • What it does: Combines 6+ standard nodes (Checkpoint loader, CLIP encoder, Latent, VAE, prompts) into 1 node.
  • Variants: "Efficiency Loader" (basic) + "Efficiency Loader (SDXL)" (for SDXL models).
  • Extras: Supports LoRA/ControlNet stacking (easily add multiple LoRAs/ControlNets without messy wiring).
Efficiency Samplers
  • What it does: An upgraded K Sampler with built-in VAE decoding + real-time preview (no extra "Preview Image" node needed).
  • Variants: "K Sampler (Efficiency)" (basic), "Advanced Efficiency" (more controls), "SDXL Efficiency" (for SDXL).
  • Extras: Works with scripts (e.g., HD upscaling) via a "Script" input port.

Quick Guide: Use Efficiency’s XY Chart

The XY Chart helps test 2 parameters (e.g., steps + samplers) at once. Here’s how:

Set up the base workflow

  1. Add "Efficiency Loader" (set model/VAE/prompts) + "K Sampler (Efficiency)" (keep default).
  2. Connect their ports.

Add the XY Chart node

  1. Link "Efficiency Loader"’s "Dependency" output to XY Chart’s "Dependency" input.
  2. Link XY Chart’s "Script" output to the sampler’s "Script" input.
  3. Set "Spacing" (image gap) to 5; set "Image Output" to "Plot".

Add parameter nodes

  1. Add "Steps" node: Set "Count=4", "Start Step=5", "End Step=20" (test 5/10/15/20 steps).
  2. Add "Sampler Scheduler" node: Set "Input Count=4", pick 4 samplers (e.g., euler, dpm_sde, dpmpp_2m, lcm).
  3. Link "Steps" to XY Chart’s X input; link "Sampler Scheduler" to XY Chart’s Y input.

Generate & compare

  1. Click "Add Prompt to Queue" — the XY chart will show results for all parameter combinations.
