GPEN‑BFR‑2048.pth is a PyTorch checkpoint for the model trained for Blind Face Restoration (BFR) at a maximum output resolution of 2048 × 2048 pixels . The checkpoint contains the learned weights of a deep neural network that can take a low‑quality facial image (blurred, noisy, compressed, low‑resolution, etc.) and produce a high‑fidelity, high‑resolution reconstruction that preserves identity, fine details, and natural lighting.
