US authors George RR Martin and John Grisham are suing ChatGPT-owner OpenAI over claims their copyright was infringed to train the system.
Martin is known for his fantasy series ‘A Song of Ice and Fire’, which was adapted into HBO show ‘Game of Thrones’.
ChatGPT and other large language models “learn” by analysing a massive amount of data often sourced online.
The lawsuit claims the authors’ books were used without their permission to make ChatGPT smarter.
OpenAI said it respected the rights of authors, and believed “they should benefit from AI technology”.
The case has been brought to the federal court in Manhattan, New York, by the Authors Guild, a trade group in the US working on behalf of the named authors.
