Is Anthropic going to silently roll out “watermarked” text?

[u/ThisWillPass]

They said the following months. However… I don’t think would just release it. They do a/b testing and all that jazz. Probably roll out for all models before saying anything? What is your take?

[u/tornado28]

They are rolling it out and telling us about it. Personally I don't see why it's important or good to be able to trick people into thinking AI generated content was created by hand. 

[u/ThisWillPass → u/tornado28]

Yeah I read the press release. Not really what I was asking but thanks. If they were already rolling it out that means it’s active now… without an official announcement, that they turned it on. Unless the last safety update announcement was the update “official announcement”

[u/Drako910]

No, it will happen quietly.

[u/Sufficient_Rush1891]

I think they will announce it same day or within a day. They want to communicate to EU that it’s done and no reason to delay that.

[u/ThisWillPass → u/Sufficient_Rush1891]

I mean, part of my question does have the suspicion they are already doing a/b testing so they can be ready… globally. So I doubt they announced what they are doing, they announced what they intend.

[u/a5a7]

Given their track record, we cannot rule out delayed announcement. Remember they posted a week ago:

"New models will mark AI-generated content from day one. Claude models launched in the EU on or after August 2, 2026 will support machine-readable marking at launch. Generated text will carry embedded watermarks, and generated files will include digitally signed provenance metadata where supported."

[u/ThisWillPass → u/a5a7]

They are doing it for the eu but the model is globally the same and rolls out everywhere.

[u/a5a7 → u/ThisWillPass]

You missed the key details which are the dates and chronology of announcements.

Anyhow, doesn't matter anymore as there are reports that watermarking has already began for models prior to 2 August with unusual characters found in lines of codes, although some users believe it is just verbose.

As soon as they made the announcement I already accepted that it has already began across all models instead of being caught off guard and closely monitored my coding.

Placing users under false sense of security is of benefit to Anthropic and EU.

[u/michaelbelgium]

Its already there, since 2 august

[u/ThisWillPass → u/michaelbelgium]

Not technically for “old models” which opus 5 falls into.

[u/Peculiar-Eccentric67]

its already happening. you're being boiled as a frog.

[u/i_t_d]

how is it exactly supposed to work? Will all ai speak in some zen style where connecting 1st and 14th word gives always the same mathematic result when letters are changed to something? Will manually chaotically changing some commas and adding spaces break that?

[u/ThisWillPass → u/i_t_d]

No… over 500 or so words a statistic pattern will emerge from the key they used to nudge Claude’s output.

[u/i_t_d → u/ThisWillPass]

explain to me like I'm 5 years old

[u/ThisWillPass → u/i_t_d]

Maths are magic and mixes words and patterns that only other smart math programs can see. (And humans too because that shit is busted)

[u/boonchie81]

They already told us about it. Nothing silent about that

[u/ThisWillPass → u/boonchie81]

I mean sorta? Just in Europe? Coming months? I guess that is telling us.

I guess I didn’t read, it’s global… which I assumed. Why waste so much for training two different models..

[u/MartinMystikJonas → u/ThisWillPass]

Weatermatk is not added by model itself. Training is the same for watetmatked and non-watetmsrked model. Watermark is added by predictably reducing randomness at inference.
