Artists using Stable Diffusion often generate faces with "dead eyes" or blurry mouths. Running the output through GPEN-BFR-2048 (via the Imitation UI or ComfyUI custom nodes) "hardens" the facial features without changing the artistic style.
GPEN [1] remains one of the most efficient, but its fixed latent dimension limits expressiveness. Our work is the first to systematically study the effect of latent dimensionality up to 2048 for BFR.
KeyError: 'params_ema' Solution: The file might be a raw checkpoint. You need to access the state dict via torch.load('file.pth', map_location='cpu')['params_ema'] .
What makes the 2048 variant different from its smaller siblings?
This post is for developers and AI enthusiasts working with high-resolution face restoration. 🚀 Level Up Your Face Restoration with GPEN-BFR-2048
We use a composite loss:
While standard models often cap out at 512px or 1024px, the 2048.pth variant is optimized for professional-grade, large-scale prints and 4K displays.
When should you reach for gpen-bfr-2048.pth over other models (like GFPGAN or CodeFormer)?
