The company conducted a massive experiment on its watermarking tool SynthID’s usefulness by letting millions of Gemini users rank it.

Google's DeepMind division has announced a watermarking tool focused on detecting AI-generated text with high accuracy.

DeepMind isn't stopping at labeling only Google Gemini output. SynthID watermarking and detection have already been open-sourced and offered to developers of other AI models, to encourage its adaptation for use with today's many competing LLMs.

SynthID is a technology from Google DeepMind that watermarks and identifies AI-generated content by embedding digital watermarks directly into AI-generated images, audio, text, or video.

The move gives the entire AI industry an easy, seemingly robust way to silently mark content as artificially generated, which could be useful for detecting deepfakes and other damaging AI content before it goes out in the wild.

Developers can now use Google’s SynthID Text technology to determine whether text was made by their own AI models.
