A group of U.S. authors, including Pulitzer Prize winner Michael Chabon, have filed a lawsuit against OpenAI in a federal court situated in San Francisco.

The suit alleges that OpenAI used their writing without permission to train its popular artificial intelligence-powered chatbot ChatGPT.

In their legal filing, authors Michael Chabon, David Henry Hwang, Matthew Klam, Rachel Louise Snyder, and Ayelet Waldman contend that OpenAI illicitly duplicated their literary works, employing them to instruct ChatGPT in crafting responses to human text inputs, all without obtaining proper authorization. They are seeking unspecified damages and an injunction to stop OpenAI from using their work.

Previously in 2022, a group of authors sued OpenAI for using their works to train its GPT-3 language model. That lawsuit is still pending.
