OpenAI's GPT Store is facing copyright complaints, with a publisher alleging that some chatbots were created using its copyrighted textbooks, thereby illegally scraping content. OpenAI has taken down some of the bots, but the issue has triggered broader copyright concerns and discussions about AI ethics in the sector. The store allows developers to upload extra files, including entire books, to power their bots, leading to a Danish publisher spending hours tracking down his textbooks. This situation underscores the ongoing battle between copyright holders and AI companies, and the potential for more complaints from rights holders. Some experts suggest that certain uses of copyrighted works by the bots could be considered 'fair use'.
