Can Witness detect Stable Diffusion images?
Stable Diffusion and its many community variants are part of the families Witness was trained on. Heavily fine-tuned or upscaled variants can behave differently.
Open-source outputs often carry no provenance data at all, so detection rests on the pixels.
What helps and what hurts
What helps
- Use the original file.
- Look at the heatmap for texture and edge regions.
- Run the generator attribution view where available to see the closest family.
Where detection gets harder
- Custom fine-tunes, upscalers and inpainting can move outputs away from what detectors have seen.
- Screenshots, heavy compression and resizing remove the traces detectors rely on, and can also make real photos look suspicious.
- New versions of a generator can be missed until detection is updated.
How to read this page
- Coverage statements come from Witness's own internal evaluation, not an independent benchmark.
- No accuracy percentage is published for this generator.
- Witness reports a likelihood with a confidence score. It does not prove anything on its own.
How it works
- 01
Drop in the file
Upload an image or video, or paste a link, or right click any image in Chrome with the extension.
- 02
Witness checks it
Several detection methods run in parallel, plus checks for provenance data such as Content Credentials and metadata.

You get a likely real or likely AI-generated verdict with a confidence percentage and a plain-language explanation.
Frequently asked questions
Can Witness detect Stable Diffusion images?
Often, yes, with a confidence percentage. Fine-tuned models and edited outputs are harder.
Does it tell me which Stable Diffusion version made an image?
Witness can show the closest generator family for some images. Treat it as a guess, not a fingerprint.
Is a Witness result proof?
No. Witness gives a likelihood and a confidence percentage, plus an explanation. Use it as a second pair of eyes, not as a final ruling.
