The Batch Latents node combines multiple latent inputs into a single batch. It takes a variable number of latent samples and merges them along the batch dimension, allowing them to be processed together in subsequent nodes. This is useful for generating or processing multiple images in a single operation.

Inputs

Parameter	Data Type	Required	Range	Description
latents	LATENT	Yes	N/A	The first latent sample to be included in the batch.
latent_2 to latent_50	LATENT	No	N/A	Additional latent samples to be included in the batch. You can add between 2 and 50 latent inputs in total.

Note: You must provide at least two latent inputs for the node to function. The node will automatically create input slots as you connect more latents, up to a maximum of 50.

Outputs

Output Name	Data Type	Description
output	LATENT	A single latent output containing all the input latents combined into one batch.
