Actually I didn't. If you read my comment you'd understand I would need the LLM to demonstrate the model that does the actual combining (which obviously wouldn't be an LLM). Seeing as there are currently no models that have watermarking, I'd have to write one myself to test the actual model that does the combining to circumvent the watermark. Either you didn't understand this, or you're once again taking single sentences out of context and making semi-valid points that don't have any relevancy to the orignal discussion.

But honestly I feel like this is completely besides the point. I've given you a high-level explanation of how these watermarks can be defeated and you seem to be the only one who does not understand how they work.
