Real-ESRGAN-x4plus (MLX)

Apple MLX fp16 port of Real-ESRGAN RealESRGAN_x4plus (RRDBNet, ×4), for super-resolution on Apple Silicon. Converted from the official xinntao/Real-ESRGAN release checkpoint (BSD-3-Clause).

Usage

bash

pip install realesrgan-mlx   # https://github.com/xocialize/realesrgan-mlx
realesrgan-mlx -i input.png -o out/ -n RealESRGAN_x4plus

python

from realesrgan_mlx.pipeline_mlx import make_upsampler, upscale_image
up = make_upsampler("RealESRGAN_x4plus", tile=256)   # tile>0 caps memory on large images
out = upscale_image("input.png", up)

make_upsampler downloads these weights automatically.

Details
