Real-ESRGAN "realesr-general-x4v3" weights — BSD-3-Clause, (c) 2021 Xintao Wang.
Source: https://github.com/xinntao/Real-ESRGAN (release v0.2.5.0). License: realesrgan-LICENSE.txt
Modification: PyTorch weights converted to raw float32 (models-real/realesr-general-x4v3.data,
manifest .json); last-layer channels reordered for tf.depthToSpace. Output verified against the
original network (max difference < 0.00001). Runner: realesrgan.js.
Review change (2026-09-30): runner disables packed WebGL kernels during prediction
and restores the caller's setting afterwards, after shape-dependent artifacts were
observed in a full-image/tiled comparison. Real-model tiles use 36px context.
Synthetic full-image/tiled comparison passed in CPU and Chromium WebGL tests.
This is not a guarantee for every GPU, device, image or visual quality outcome.
