This does not match what GP claimed, that when prompted with the start of an article, GPT 3 (mostly) faithfully completes it. The original article also claimed that it seemed to have been patched shortly after publication.

It does match exactly what I claimed and it also states that even though the behavior was patched in GPT the ars people were able to easily reproduce it in copilot.

Its funny that the behavior was patched if OpenAI believes it isn't copyright infringement.
