Runtime conditioning scale reduction must not be carried into persisted model or LoRA weights. Keep named merger presets at 1.0 and reserve scaling for explicit custom configuration.
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
