To detect the watermark and decide whether or not textual content has been generated by an AI software, SynthID compares the anticipated chance scores for phrases in watermarked and unwatermarked textual content.
Google DeepMind discovered that utilizing the SynthID watermark didn’t compromise the standard, accuracy, creativity, or velocity of generated textual content. That conclusion was drawn from a large reside experiment of SynthID’s efficiency after the watermark was deployed in its Gemini merchandise and utilized by tens of millions of individuals. Gemini permits customers to rank the standard of the AI mannequin’s responses with a thumbs-up or a thumbs-down.
Kohli and his staff analyzed the scores for round 20 million watermarked and unwatermarked chatbot responses. They discovered that customers didn’t discover a distinction in high quality and usefulness between the 2. The outcomes of this experiment are detailed in a paper revealed in Nature as we speak. Presently SynthID for textual content solely works on content material generated by Google’s fashions, however the hope is that open-sourcing it can increase the vary of instruments it’s suitable with.
SynthID does produce other limitations. The watermark was immune to some tampering, comparable to cropping textual content and light-weight enhancing or rewriting, nevertheless it was much less dependable when AI-generated textual content had been rewritten or translated from one language into one other. It is usually much less dependable in responses to prompts asking for factual data, such because the capital metropolis of France.
