Universal NN Latent Upscaler for ComfyUI

By DenRakEiwView on GitHub →

A universal neural network latent upscaler that supports SD1.5, SDXL, Flux, and Wan2.2 models. Uses trained neural networks instead of simple interpolation for higher quality latent upscaling. Built upon the excellent foundation of [a/Ttl's ComfyUi_NNLatentUpscale](https://github.com/Ttl/ComfyUi_NNLatentUpscale) - this project extends the original work with universal model support and improved architectures.
