--- license: bsd-3-clause library_name: mlx pipeline_tag: image-to-image tags: - mlx - super-resolution - real-esrgan - image-to-image - apple-silicon --- # Real-ESRGAN-general-x4v3 (MLX) Apple **MLX** fp16 port of Real-ESRGAN **realesr-general-x4v3** (SRVGGNetCompact, ×4), for super-resolution on Apple Silicon. Converted from the official [xinntao/Real-ESRGAN](https://github.com/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 realesr-general-x4v3 ``` ```python from realesrgan_mlx.pipeline_mlx import make_upsampler, upscale_image up = make_upsampler("realesr-general-x4v3", tile=256) # tile>0 caps memory on large images out = upscale_image("input.png", up) ``` `make_upsampler` downloads these weights automatically. ## Details - **Architecture**: SRVGGNetCompact (`num_feat=64`, `num_conv=32`, `act=prelu`) - **Scale**: ×4 · **Precision**: fp16 - **Parity vs PyTorch**: full-forward 4.1e-6 (CPU fp32); fp16 vs fp32 golden 2.0e-3. - **Denoise strength**: this model ships with a paired `model_wdn.safetensors`; `build_model(..., denoise_strength=s)` blends `s*model + (1-s)*wdn` (`1.0` keeps detail, `0.0` = max denoise). ## License BSD-3-Clause (upstream Real-ESRGAN, Xintao Wang et al.).
