XY Inputs: ModelMergeBlocks //EasyUse:

The ModelMergeBlocks node is designed to facilitate the merging of two AI models by blending their respective components based on specified ratios. This node is particularly useful for AI artists who want to combine the strengths of different models to create a more versatile and powerful model. By adjusting the blending ratios, you can fine-tune the influence of each model on the final merged output, allowing for a high degree of customization and control over the resulting model's behavior and performance. The primary function of this node is to clone the first model and then integrate key patches from the second model, adjusting the blend ratios as specified by the user.

XY Inputs: ModelMergeBlocks //EasyUse Input Parameters:

model1

This parameter represents the first model to be merged. It serves as the base model that will be cloned and modified. The type of this parameter is MODEL.

model2

This parameter represents the second model to be merged. Key patches from this model will be integrated into the first model. The type of this parameter is MODEL.

input

This parameter controls the blending ratio for the input components of the models. It determines how much influence the input components of model2 will have on the final merged model. The value ranges from 0.0 to 1.0, with a default value of 1.0 and a step size of 0.01.

middle

This parameter controls the blending ratio for the middle components of the models. It determines how much influence the middle components of model2 will have on the final merged model. The value ranges from 0.0 to 1.0, with a default value of 1.0 and a step size of 0.01.

out

This parameter controls the blending ratio for the out components of the models. It determines how much influence the out components of model2 will have on the final merged model. The value ranges from 0.0 to 1.0, with a default value of 1.0 and a step size of 0.01.

XY Inputs: ModelMergeBlocks //EasyUse Output Parameters:

MODEL

The output parameter is the merged model, which is a combination of model1 and model2 based on the specified blending ratios. This merged model retains the structure of model1 but incorporates key patches from model2 as per the blending ratios provided. The type of this parameter is MODEL.

XY Inputs: ModelMergeBlocks //EasyUse Usage Tips:

• Experiment with different blending ratios for input, middle, and out to achieve the desired balance between the two models.
• Use this node to combine models with complementary strengths, enhancing the overall performance and versatility of the resulting model.
• Save different versions of the merged model with varying ratios to compare their performance and select the best one for your specific needs.

XY Inputs: ModelMergeBlocks //EasyUse Common Errors and Solutions:

"KeyError: 'diffusion_model.'"

• Explanation: This error occurs when the second model does not contain the expected key patches prefixed with diffusion_model..
• Solution: Ensure that the second model is compatible and contains the necessary key patches. Verify the model's structure before merging.

"ValueError: Ratio out of range"

• Explanation: This error occurs when the blending ratio provided is outside the acceptable range of 0.0 to 1.0.
• Solution: Adjust the blending ratio to be within the range of 0.0 to 1.0. Use the default step size of 0.01 for fine-tuning.

"TypeError: Model type mismatch"

• Explanation: This error occurs when the provided models are not of the type MODEL.
• Solution: Ensure that both model1 and model2 are of the correct type MODEL before attempting to merge them.
