    Nodes

    Koala Aspect Ratio Empty Latent

    Creates empty latents that match predefined aspect ratios from training hyperparameters.

    Inputs:

    • batch_size: Number of latents to create (1-64)
    • image (optional): Image to extract dimensions from
    • width (optional): Manual width input
    • height (optional): Manual height input

    Outputs:

    • latent: Empty latent tensor with matched dimensions
    • width: The matched width value
    • height: The matched height value
    • aspect_ratio: The matched aspect ratio value
    • info: String showing input → matched dimensions

    Usage: The node will automatically find the closest matching aspect ratio from a predefined set of training-optimized ratios, ensuring your generations use optimal dimensions.

    Supported Aspect Ratios

    The node supports 40 different aspect ratios ranging from 0.25 (512×2048) to 4.0 (2048×512), including common ratios like 1:1, 16:9, 9:16, etc.
