What information is included in the metadata or SynthID? How many bits can be encoded in a SynthID?
Can it be used to create something like nutritional labels for synthetic content? 10% synthetic text, 30 synthetic images.
Your reality was 15% synthetic today (75% mega corp, 25% open-weight neocloud).
Or perhaps a user id or fingerprint to an individual. We added that to printers long ago, this would easily enable that for every photo and image you generate too.
Don’t think that would be possible. If I paste a synthetic piece into an otherwise organic image, the synth id isn’t going to know that.
I guess the SynthID-Image paper from Oct 2025[0] was an encoder-decoder for which they tested checking a flag or a 136 bit payload in 512x512 images and the watermark's robustness after various transformations.
Presumably the deployed version is meaningfully different.
