SORKIN Can I ask you an interesting IP issue…one of the things about training on data is the idea that these things are not being trained on peoples copyrighted information historically, that’s been the concept.

MUSK That’s a huge lie.

SORKIN Say that again?

MUSK These AIs are all trained on copyrighted data, obviously.

SORKIN So you think it’s a lie when OpenAI says…none of these guys say they are training on copyrighted data?

MUSK That’s a lie.

SORKIN A straight up lie.

MUSK A straight up lie. 100%. Obviously it’s been trained on copyrighted data.
