SynthID – A tool to watermark and identify content generated through AI

I guess this is the start of a new arms race on making generated content pass these checks undetected and detecting them anyway.

Its not really an arms race; any gen AI system that doesn't explicitly incorporate a watermarking tool like this won't be detectable by tools that read the watermarks.

There is a kind of arms race that has existed for a while for non-watermarked content, except that the detection tools are pretty much Magic 8-ball level of reliability, so there's not a lot of effort on the counter-detection side.
