AI Text Watermarking Is Free And Good

Scott Aaronson, while working at OpenAI, largely solved AI text watermarking together with Hendrik Kirchner. Here is how his solution works, or see Tenobrus’s version. AI outputs are not deterministic. The AI’s job is to pick the probability of each potential next token. The token is then chosen at random. By default you use a source of pseudo-randomness for each choice, since actual true randomness is annoying.To apply the watermark, you use an otherwise identical private source of pseudo-rando...
