Can Witness detect ChatGPT and DALL-E images images?
Images from OpenAI's image tools, including DALL-E and the newer ChatGPT image generator, are part of the families Witness was trained on. Results still depend on compression and editing, and no detector is perfect.
Some OpenAI images carry Content Credentials (C2PA). Witness reads them when present, but screenshots and many uploads strip them, so their absence tells you nothing.
What helps and what hurts
What helps
- Upload the original download rather than a screenshot.
- Check Content Credentials with the C2PA checker.
- Read the confidence percentage, not only the label.
Where detection gets harder
- 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.

Frequently asked questions
Can Witness detect ChatGPT images?
Witness includes images from this family in its training and can often flag them, with a confidence percentage. It is a likelihood, not proof.
Does Witness read C2PA on ChatGPT images?
Yes, if the file still has its Content Credentials. Many platforms remove them, so a missing credential is not evidence either way.
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.
