DALL·E image detector
last updated 7 june 2026
DALL·E images (now generated through ChatGPT and GPT-4o) often carry C2PA Content Credentials that explicitly mark them as AI-made — when that metadata survives. Where it's been stripped, verifai falls back to visual analysis, scanning the page and scoring suspected AI images in one click.
OpenAI attaches C2PA "Content Credentials" to DALL·E and GPT-4o image output, so an unaltered DALL·E image can be verified as AI-generated by reading its provenance metadata. The catch: screenshots, re-saves and most social platforms strip that metadata, leaving you with visual tells and a detector.
verifai handles the common case — images already embedded in a web page, where metadata is usually long gone — by scanning what's rendered and flagging likely AI images with a confidence score.
Check Content Credentials first
If you have the original file, check it for C2PA Content Credentials (for example via the Content Authenticity Initiative's verify tool). Present-and-valid credentials are strong confirmation. But remember the asymmetry: credentials present = reliable yes; credentials absent = unknown, not no.
Visual tells when metadata is gone
DALL·E output shares the common diffusion artefacts:
- garbled text and lettering within the image
- hands and small anatomy errors
- a smooth, slightly illustrative rendering style
- lighting and reflections that don't fully cohere
frequently asked
Do all DALL·E images have a watermark?
DALL·E images carry C2PA Content Credentials metadata rather than a visible watermark, and that metadata is frequently removed when images are screenshotted or re-uploaded. So it can't be relied on for images already on the web.
How does verifai detect DALL·E images?
verifai analyses the rendered images on the page and returns a confidence score. In this MVP that score is an on-device heuristic; the design supports a hosted model in production.
