XY Inputs: ModelMergeBlocks //EasyUse (XYplot_ModelMergeBlocks) - ComfyUI-Easy-Use

Description

This node builds X/Y plot data for comparing model merge block configurations between two checkpoints. Connect the X_Y output to the X or Y input of an XY Plot node to generate a grid of images that vary by the merge block values you specify.

It is a data-generation node only: it does not load or merge models by itself. The actual checkpoint loading and model merging happen later in the sampling/plot pipeline using the parameters captured here.

Inputs

All inputs are required.

Input	Type	Default	Description
`ckpt_name_1`	COMBO	—	First checkpoint to use in the model merge.
`ckpt_name_2`	COMBO	—	Second checkpoint to use in the model merge.
`vae_use`	COMBO	`Use Model 1`	Which checkpoint's VAE to use with the merged model.
`preset`	COMBO	`preset`	Merge preset that determines how the merge blocks are interpreted and how `values` should be parsed.
`values`	STRING	—	Values describing the merge block setup to evaluate.

Input details

ckpt_name_1 and ckpt_name_2 select the two checkpoints to merge. Both are required; there is no default checkpoint.
vae_use controls which VAE is attached to the merged result. The default is Use Model 1, but the other checkpoint's VAE can also be selected, making it possible to keep a specific VAE independent of the merge source.
preset selects the merge configuration used to translate the input values into model merge block settings. The available presets are provided by the ComfyUI-Easy-Use installation.
values is the parameter sweep for the XY plot. Its expected syntax follows the selected preset: simple presets may take a comma-separated list of numeric merge ratios, while block-based presets may use block:value pairs to target specific merge blocks.

Outputs

Output	Type	Description
`X_Y`	`X_Y`	XY plot data object. Pass this to the X or Y input of an XY Plot node.

Usage Notes

This node does not produce an image, model, or latent. It only produces X_Y data for use with a separate XY Plot node.
To run a straightforward merge-weight comparison, set both checkpoints, choose a VAE, leave preset as preset, and enter the merge values to test in values.
For block-specific sweeps, select a preset that exposes block information and use the matching block:value syntax in values.
Make sure values is non-empty and correctly formatted for the selected preset; an empty or invalid values string will cause the XY plot step to fail.
Since no merged model is created until the XY Plot pipeline runs, this node is inexpensive to rewire and evaluate.
