SynthId is basically an AI fingerprint that some AI companies chose to implement to make identifying whether an image is generated by AI easier.
Unlike previous methods that looks for clues whether something is AI generated or not SynthID has a much lower false positive rate. If synthID is detected it is basically guaranteed that the image is AI generated AFAIK.
Note that just because an image is AI generated does not necessarily mean the underlying image is fake. An image that was upscaled or enhanced with AI will still have SynthID fingerprints.
Also note that even if an image is generated with a SynthID fingerprint, if the image is then modified enough, it could degrade or remove the fingerprint.
There are three main issues with SynthID. (1) Each LLM company implements their own SynthID fingerprint. Many of them can only identify their own fingerprint. As an example, this website by open ai can only identify images generated by chatgpt. That being said, a more recent tool by google seems to be able to detect synthid from several different LLMs.
(2) SynthID is relatively new. Only OpenAI has a public api for detecting synth ID. The google one is still private. The tool I am using uses OpenAI’s API meaning it can only identify images generated by ChatGPT.
(3) SynthID is something that is added by the LLM on purpose. Not all LLMs mark images they generate with SynthID. Older AI generated images and images generated by certain models will not have SynthID fingerprints.

What are you using for this?
Not that I’d really trust AI-powered tools to detect AI correctly, but it looks like something you’re running in-browser?
