alt Hacker NewsThe reason it's not "fishy laundering " is fundamental to copyright: copyright protects expression, not ideas. That's why in cases where expressing the same idea would result in the same text, the courts have ruled that the expression is not copyrightable rather than that this gives a monopoly to the first person to copyright it. (NB I am not a lawyer, etc)
Yeah, but the whole reason clean room RE uses two different teams of people is so you can demonstrate that the second team is not simply reproducing that the original expression -- it would have been impossible for them to do so because they had never seen it.
You lose that if you use an LLM which was trained on the original expression.
To keep the clean room clean, you'd need to use an LLM which you could prove had never seen the original.
