real-esrganReal-ESRGAN is an AI image upscaler tuned for illustration, anime and hand-drawn or painted artwork. It enlarges by up to 10x — reaching 4K, 8K and 10K print resolution — while keeping linework crisp and flat colors clean, which is exactly where diffusion-based upscalers tend to repaint and go soft. Optional face enhancement (GFPGAN) sharpens faces in the same pass. Honest scope: on real photographs it mainly enlarges; it does not remove blur, repair old-photo damage, or denoise, so use it to make art bigger for print and high-DPI screens, not to restore photos. Billed a flat $0.004 per image (scale and face enhance included), charged only on success, one API key on apimodels.app.
