its realistic to assume anthropic (and other frontier labs) have already gobbled the entire surface of the public internet into training data, plus so much more llm-generated traning data, that if you have public works and a model has enough parameters, i guess you are now 'in the models knowlege' the same way a figure like michael jackson or elon musk would be 'baked into the weights of the model' scary.

What they claim is a bit irrelevant tbh, it's on their servers, their DB, they do, they don't, we will never know, so we must assume they do. It goes against their business to trash data for no reason, so why would they.

There's so much public data about us on the internet, that every single one of us is likely in every frontier model's training data by now.
