short_description: Memorization detection for Stable Diffusion v1.4

# 🛡️ MemGuard
Detect **training-data memorization** in Stable Diffusion v1.4 outputs.
Enter a prompt → MemGuard generates the image and scores it with the
anisotropy-of-log-probability metric from
[Detecting and Mitigating Memorization in Diffusion Models through Anisotropy of the
Log-Probability](https://openreview.net/forum?id=HTPGy5ydAY) (ICLR 2026). Scores
at/above the **0.9** threshold are flagged as memorized.
**Source code, library, API & Docker:** https://github.com/rohanasthana/memguard
> **Note:** this Space runs on free CPU hardware, so image generation is slow
> (~100 s/denoising step). Lower the image-steps slider to finish sooner.
