ComfyUI-ModelUtils

A collection of ComfyUI custom nodes for inspecting, modifying, merging, and creating model files. Supports Models, TextEncoders, LoRAs, Checkpoints, and Embeddings.

Features

  • MetaKeys – Inspect and display metadata and tensor keys from model files
  • RenameKeys – Batch rename tensor keys using pattern matching
  • PruneKeys – Remove unwanted layers/keys from models
  • Mergers – Combine 2 or 3 models with configurable blend modes and ratios
  • LoRA Extraction – Extract LoRA adapters from model pairs using various SVD rank selection methods (Fixed, Ratio, Quantile, Knee-detection, Frobenius-norm)

    • Example Workflows

    📥 GetMetaAndkeys.json

    📥 LoRA_Extract_nodes.json

    📥 Merging_Examples.json

    📥 RenameKeysInModel.json

    The LoRA extraction functionality was inspired by and references the excellent work from:

  • kohya-ss/sd-scripts – Training scripts for Stable Diffusion
  • KohakuBlueleaf/LyCORIS – Advanced LoRA techniques
  • bmaltais/kohya_ss – Windows-friendly GUI for sd-scripts
