Yes it does, because the entire "watermark" is based on biasing the choice of certain tokens over others. It's extremely easy to attack.

No the "watermark" isn't in metadata or characters. It's a token bias that causes certain tokens to be selected over others in a way that doesn't change the overall meaning of the text, but it can be recovered that it was made by claude. You can still destroy it by rewriting pieces of the output or running it through a translator and back.

One of the reasons Open AI decided not to do this is they thought it could cause a DITHPARATE IMPACT to ESL users

They statistically bias certain tokens to enough of an extent that it leaves a detectable pattern, but they aren't releasing the exact pattern afaict. I would just put Claude's output into gpt and tell it to rewrite it in different words while maintaining the meaning.

Open AI researched the same thing, and they decided not to do it, and one of their reasons was that it is really easy to break. Apparently also the more you try to harden it the more it has an affect on the quality of the output itself.

Yeah that does seem like a good analogy. Like meter is nice to have for poetry, but at the same time it is constraining your generative creative capability, forcing you to make choices to fit the meter. Where here it probably comes down to if you bias too many tokens then you get a shittier output. More tokens you bias, more resilient the watermark, but then you risk forcing worse choices to fit the algorithm.

You could watermark AI text by using a secret key to bias otherwise natural word choices.

At selected points, a keyed PRNG decides which of several semantically equivalent choices is preferred. Those choices encode bits, and a verifier with the same key checks whether the observed choices correlate with the expected pattern.

For example:

"however" = 0, "but" = 1

"large" = 0, "big" = 1

"because" = 0, "since" = 1

If the secret pattern is:

1 0 1 1 0 0 1...

the model subtly favors the corresponding choices. To a reader, the prose still looks completely normal.

A more sophisticated version would not use obvious synonym pairs. Instead, candidate next tokens could be secretly divided into two groups with something like:

bit(token) = HMAC(K, context || token) mod 2

To encode a 0, slightly favor tokens from group 0; to encode a 1, favor group 1. The result is a keyed statistical signature rather than an obvious hidden message.

You also would not need every bit to survive. Add redundancy with an error-correcting code, parity bits, and repeated/interleaved copies of the watermark throughout the text. Then even if large sections are deleted, reordered, or rewritten, the verifier can recover enough surviving signal to identify the watermark statistically.

For example, across 500 surviving tokens, if 68 percent match the secret expected groups instead of the roughly 50 percent expected by chance, the verifier can assign a confidence score that the text came from the watermarked generator.

Yeah its retarded though because you can technically destroy it just by changing one token, because that can alter the watermark state for subsequent positions. Theoretically, depending on the specific strategy they are using for biasing it, and which token you pick. But the more robust they try to make the watermarking, the more constrained and janky the writing and output capability becomes.

A pattern is encrypyed into the text. Think something like making every word occurring in a prime number sequence starting with an advancing vowel, but obviously more complicated. An AI could write anything under those rules without changing the content or quality that much. But yeah, obviously anything encrypted into plain text can be destroyed by simply changing a couple words.

Retardless, this isn't some bait thread with a misleading title. If it doesn't interest you don't click on it. And especially don't click it again when the link turns blue to read updates. The frontpage is 90% NSAM spam, it's not like this thread getting bumped is competing with quality content.
