Yeah, google’s image generation tools intentionally leave a fingerprint so they can determine if an image was created by their AI tools. It’s basically the only thing I use their AI for.
https://deepmind.google/models/synthid/ It’s pretty interesting, and I’m glad they do it. I wish it were a requirement for all AI-gen images/videos/etc.
If I can’t find an image that looks like it might be AI on a reverse image search before ~2020, I run it through there to check if it was Gemini-created. It’s pretty helpful if you’re borderline like this one.












Sorry, I thought Google’s SynthID was common knowledge. They intentionally add a fingerprint to images/videos/audio created by their AI gen systems that they have the ability to detect. To my knowledge when you call it with @synthid or @detectai, it doesn’t even activate the actual LLM, just calls the tool directly.
I find it helpful in cases like this where a reverse image search doesn’t show anything before 2020, but an image smells like AI. Only thing is it can’t detect if an image was created by a different AI, so a negative result is not proof that something is not AI.
