## What does inpainting do?

Inpainting is the technique of filling a masked region of an image with new pixels that match the surrounding content. Classical methods copied nearby texture; since 2021 diffusion models generate the fill from a text prompt, and Stability AI’s 2022 inpainting checkpoint trained for 200,000 extra steps at 512×512 made the method the standard engine of undress apps.

## How does diffusion inpainting work?

A diffusion model learns to remove noise from images step by step. For inpainting, the pipeline takes three inputs: the image, a binary mask and a prompt. It encodes the image into latent space, adds noise, and at each denoising step keeps the unmasked latents fixed while regenerating the masked ones under the prompt. In the Diffusers pipeline the defaults are 50 steps,

guidance 7.5 and strength 1.0, meaning the masked area is fully regenerated; the base model and any LoRA adapters decide what the fill looks like. By decomposing the image formation process into a sequential application of denoising autoencoders, diffusion models (DMs) achieve state-of-the-art synthesis results on image data and beyond. — Rombach et al., latent diffusion paper

## Why does every undress app depend on it?

An undress app is an inpainting pipeline with an automatic mask. A segmentation model marks the clothing, the mask goes to an inpainting checkpoint fine-tuned on nude imagery, and a fixed internal prompt requests skin. Nothing is recovered from under the fabric; the region is invented. Test notes in the Clothoff AI clothes-removal tests show the typical failures: mismatched

skin tone, duplicated navels, merged hands. The how undress apps work article illustrates each step.
