We have just released a paper that allows us to extract several megabytes of ChatGPT’s training data for about two hundred dollars. (Language models, like ChatGPT, are trained on data taken from the public internet. Our attack shows that, by querying the model, we can actually extract some of the exact data it was trained on.) We estimate that it would be possible to extract ~a gigabyte of ChatGPT’s training dataset from the model by spending more money querying the model.
