Authors and publishers, who are suing OpenAI, secured access to internal Slack messages and emails discussing the deletion of pirated books.

Both Anthropic and OpenAI have been accused of training their AI models on copyrighted materials uploaded to a piracy website called LibGen.

Communications show that OpenAI deleted the dataset, a move that plaintiffs argue could be construed as intentional destruction of evidence. Judge Ona Wang has already found that OpenAI improperly withheld materials, per Bloomberg.
