Fix Model Paths

ComfyUI Fix Model Paths 🦊

English | Русский

Fixes broken model paths in ComfyUI workflows by trying to find the same name, or the needed variant, in subfolders.

Installation

Copy or clone the plugin folder into:

ComfyUI/custom_nodes/

Restart ComfyUI.

No extra Python packages are required.

How to use

Fix the whole workflow

• Open the workflow in ComfyUI.
• Right-click an empty area of the canvas.
• Click Fix Model Paths 🦊.

The plugin will try to replace missing paths with matching local models.

Fix one node manually

Use this if the automatic fix cannot choose the right model.

• Right-click the broken node.
• Click Fix Node 🦊.
• Select the correct model in the node itself.
• Confirm the replacement:
  • either right-click the node again and click Save Fixed 🦊;
  • or click Save Fixed 🦊 in the menu that appears in the upper-left part of the node.

The saved fix will be reused next time.

Search for a missing model

Right-click a broken node and click Find Model 🦊.

This opens a web search for the missing model name.

Matching rules

Names are matched loosely: case and separators are ignored (flux_dev = FluxDev), and precision/quantization words (fp8, bf16, Q4_K_S, e4m3fn, scaled, ...) are ignored.

To adjust this, open:

Right-click canvas -> Model Name Rules 🦊

• Ignored words: add your own words such as kj or comfy-org, or switch built-in groups off.
• Aliases: treat one word as another, e.g. encoder = enc.
• Saved replacements: exact replacements saved by Save Fixed 🦊; remove the wrong ones.

Everything is edited with buttons, nothing to type as JSON. Your rules are stored in model_matching_rules.local.json (a .bak copy is kept on every save); old "model postfixes" are migrated into ignored words automatically. After Save Fixed 🦊 the plugin may offer to remember a replacement as a general rule. Version numbers (2509 vs 2511) never become rules.
