Launch DiffSlider Tool

Built for rigorous pixel-level evaluation

Super-resolution models (ESRGAN, Magnific, Topaz, SwinIR) are judged strictly by sharpness, edge fidelity, and artifact suppression. Typical image hosts recompress uploads into lossy WebP, ruining benchmark validity.

DiffSlider preserves byte-for-byte pixel accuracy with 0 re-encoding, so researchers and creators see the exact mathematical output of their models.

Four diagnostic modes for AI research

Switch between a classic split slider, synced side-by-side view, blink toggle, or a pixel-difference heatmap that highlights synthesized textures and hallucinated artifacts.

Clinical & Photography Pro Tips

Scale your low-res source image with nearest-neighbor interpolation to match output dimensions before uploading.
Export PNG format to ensure clean artifact verification.
Share interactive comparison links on HuggingFace model cards, Reddit r/StableDiffusion, and GitHub repos.
