Quellenbeschreibung

No custom nodes needed! This is a very simple workflow for merging SDXL models by blocks/layers. You can load it, select 2 models, adjust the merge ratio, and you can start generating

As general info: IN blocks: contain concepts/composition/etc. OUT blocks: contain style/aesthetics The further away the blocks are from the middle, the closer they are to pixel level

SDXL has 20 blocks while SD1.5 has 26 blocks! Don't confuse them since most guides might show 26 blocks or IN11/OUT11 like in the image below. The merging logic stays the same though.

Here is an image from this article that helped me understand different blocks: Here is another great article by RestlessDiffusion giving a tutorial on block merging in A1111/Forge using the SuperMerger extension and showing the effects of different merge ratios:

KI-generierter Kommentar

KI-generierte Erklärung auf Grundlage von Quellen- und Konfigurationsdetails. Vorschläge sind klar gekennzeichnet.

Zweck

Use this ComfyUI workflow to merge two SDXL models by blocks or layers, adjust the merge ratio, and generate images.

Fluss

Load the workflow, select two models, adjust the merge ratio, and start generating.

Eingaben und Ausgaben

The main inputs are two SDXL models and a merge ratio.
The workflow includes image-preview and image-saving steps named PreviewImage and SaveImage.

Einrichtung

The workflow targets SDXL 1.0, and its description says no custom nodes are needed.

Abhängigkeiten

Listed node names include CheckpointLoaderSimple, CheckpointSave, CLIPMergeSimple, CLIPTextEncode, EmptyLatentImage, and KSamplerAdvanced.
Other listed node names are ModelMergeSDXL, PreviewImage, SaveImage, VAEDecode, and VAELoader.
Listed model entries are 4thTailAnimeHentai_050.safetensors, 4thTailAnimeHentai_v045.safetensors, ponyStandardVAE_v10.safetensors, and checkpoints/ComfyUI.

Konfiguration

IN blocks are described as containing concepts and composition, while OUT blocks are described as containing style and aesthetics.
Blocks farther from the middle are described as closer to the pixel level; SDXL has 20 blocks, while SD1.5 has 26.

Vorsichtsmaßnahmen

When following a block-merging guide, check whether its numbering refers to SDXL's 20 blocks or SD1.5's 26.
