ComfyUI Node: sudo latent upscale

sudo latent upscale:

The SudoLatentUpscale node is designed to enhance the resolution of latent images generated by Stable Diffusion 1.5 using advanced neural network techniques. This node specifically focuses on upscaling latent images by a factor of 2x, leveraging the power of neural networks to maintain high-quality details and textures. It is optimized for fp32 precision, ensuring that the upscaled images retain their original quality without significant loss of detail. This node is particularly useful for AI artists looking to improve the resolution of their generated images while preserving the intricate details and features that make their art unique.

sudo latent upscale Input Parameters:

latent

The latent parameter represents the input latent image that you want to upscale. This parameter is crucial as it contains the initial low-resolution image data that will be processed and enhanced by the neural network. The quality and characteristics of the input latent image directly impact the final upscaled output.

version

The version parameter specifies the model version to be used for upscaling. Different versions may have varying architectures and capabilities, tailored for specific upscaling tasks. For instance, the DAT12x6_l1_eV2-b0_contextual_1.5 version uses a deep attention transformer model with pixel shuffle upsampling, while the CRAFT7x6_l1_eV2-b0_1.5 version employs a different architecture optimized for lightweight super-resolution. Choosing the appropriate version can significantly affect the quality and performance of the upscaling process.

sudo latent upscale Output Parameters:

samples

The samples output parameter contains the upscaled latent image. This parameter holds the enhanced image data after processing by the neural network, ready for further use or final rendering. The upscaled image retains the original content but with improved resolution and detail, making it suitable for high-quality outputs.

sudo latent upscale Usage Tips:

• Ensure that your input latent image is of good quality to achieve the best upscaling results. Poor quality inputs may lead to suboptimal upscaled images.
• Experiment with different model versions to find the one that best suits your specific upscaling needs. Each version may offer unique benefits depending on the type of image and desired output quality.
• Utilize the node in a workflow where high-resolution outputs are essential, such as in detailed artwork or when preparing images for large prints.

sudo latent upscale Common Errors and Solutions:

"Model not found for the specified version"

• Explanation: This error occurs when the specified model version is not available or incorrectly specified.
• Solution: Verify that the version parameter is correctly set to one of the supported versions, such as DAT12x6_l1_eV2-b0_contextual_1.5 or CRAFT7x6_l1_eV2-b0_1.5.

"Input latent image is not in the correct format"

• Explanation: This error indicates that the input latent image does not meet the required format or specifications.
• Solution: Ensure that the input latent image is correctly formatted and compatible with the node's requirements. Check the data type and dimensions of the input image.

"Device not supported for model execution"

• Explanation: This error occurs when the specified device for model execution is not supported or unavailable.
• Solution: Verify that the device parameter is set to a supported device, such as a compatible GPU, and that the necessary hardware and drivers are properly installed.
