My understanding is that the copyright applies to reproductions of the work, which this is not. If I provide a summary of a copyrighted summary of a copyrighted work, am I in violation of either copyright because I created a new derivative summary?

Quoting this comment from the HN thread:

On information and belief, the reason ChatGPT can accurately summarize a certain copyrighted book is because that book was copied by OpenAI and ingested by the underlying OpenAI Language Model (either GPT-3.5 or GPT-4) as part of its training data.

While it strikes me as perfectly plausible that the Books2 dataset contains Silverman’s book, this quote from the complaint seems obviously false.

First, even if the model never saw a single word of the book’s text during training, it could still learn to summarize it from reading other summaries which are publicly available. Such as the book’s Wikipedia page.

Second, it’s not even clear to me that a model which only saw the text of a book, but not any descriptions or summaries of it, during training would even be particular good at producing a summary.

We can test this by asking for a summary of a book which is available through Project Gutenberg (which the complaint asserts is Books1 and therefore part of ChatGPT’s training data) but for which there is little discussion online. If the source of the ability to summarize is having the book itself during training, the model should be equally able to summarize the rare book as it is Silverman’s book.

I chose “The Ruby of Kishmoor” at random. It was added to PG in 2003. ChatGPT with GPT-3.5 hallucinates a summary that doesn’t even identify the correct main characters. The GPT-4 model refuses to even try, saying it doesn’t know anything about the story and it isn’t part of its training data.

If ChatGPT’s ability to summarize Silverman’s book comes from the book itself being part of the training data, why can it not do the same for other books?

As the commentor points out, I could recreate this result using a smaller offline model and an excerpt from the Wikipedia page for the book.

Exactly, though I’d like to get a PR in to not show that on the admin screen, or in the very least to make the list collapsed by default. I think I’ll work on that today.

Those are bans where the user has been banned from their home instance. It actually doesn’t make a lot of sense that they show up in our admin panels since a user banned from their home instance won’t be able to authenticate and access remote instances with that account.

Unfortunately from what I’ve seen, that doesn’t actually result in a notification
