The StableCascade_EmptyLatentImage node creates empty latent tensors for Stable Cascade models. It generates two separate latent representations - one for stage C and another for stage B - with appropriate dimensions based on the input resolution and compression settings. This node provides the starting point for the Stable Cascade generation pipeline.

Inputs

ParameterDescriptionData TypeRequiredRange
widthThe width of the output image in pixels (default: 1024, step: 8)INTYes256 to MAX_RESOLUTION
heightThe height of the output image in pixels (default: 1024, step: 8)INTYes256 to MAX_RESOLUTION
compressionThe compression factor that determines the latent dimensions for stage C (default: 42, step: 1)INTYes4 to 128
batch_sizeThe number of latent samples to generate in a batch (default: 1)INTNo1 to 4096

Outputs

Output NameDescriptionData Type
stage_cThe stage C latent tensor with dimensions [batch_size, 16, height//compression, width//compression]LATENT
stage_bThe stage B latent tensor with dimensions [batch_size, 4, height//4, width//4]LATENT
