Kontext-Unblur-Upscale

The Kontext-Unblur-Upscale is an experimental adapter for black-forest-lab's FLUX.1-Kontext-dev, designed to upscale low-quality images to 4K resolution, enhancing sharpness, clarity, and fine details while preserving the original texture, colors, lighting, and natural appearance. The model effectively removes noise, blur, and compression artifacts, ensuring high-fidelity restoration and visually realistic results. It was trained on 1,000 image pairs (500 start images and 500 end images) to deliver precise, artifact-free upscaling performance.

[photo content], upscale the low-quality image to 4K resolution, enhancing sharpness, clarity, and fine details while preserving the original texture, colors, lighting, and natural appearance. Remove noise, blur, and compression artifacts without over-smoothing or distorting facial or object features. Ensure realistic depth, balanced contrast, and accurate tones, achieving a high-definition, lifelike result that maintains the integrity of the original image.

You modified the prompt, altering its properties and subjective elements. Note: this is an experimental adapter and may contain artifacts.
