Load Checkpoint (Auto VAE/CLIP) – ComfyUI Custom Node

Load Checkpoint (Auto VAE/CLIP)

Loads a checkpoint and automatically swaps in an external VAE and/or CLIP, based on a simple mapping file. No more manually wiring a separate VAE loader for every model.

Features:

- Per-checkpoint mapping by exact file name

- Wildcard patterns (e.g. pony/*)

- Per-architecture defaults (e.g. @SDXL, @SD15)

- External CLIP for SD1.5, SD2 and SDXL

- "info" output showing what was actually loaded

- Without a mapping file, it works like the standard checkpoint loader

Setup:

Copy model_map.example.json to model_map.json in the folder ComfyUI-X4Lch3mist/auto_checkpoint/ and adjust it to your files.

Entries are matched in this order:

1. Exact checkpoint name, as shown in the dropdown

2. Wildcard pattern

3. Architecture, prefixed with @

VAE names refer to files in models/vae, CLIP names to files in models/text_encoders.

Installation:

1. Download and unzip

2. Move the folder "ComfyUI-X4Lch3mist" into ComfyUI/custom_nodes/

3. Restart ComfyUI

You'll find the node under X4Lch3mist/loaders.

Also using my Free Resolution Selector? Just unzip both into the same folder, they merge automatically.

GitHub version coming soon
