A group of U.S. authors including Pulitzer Prize winner Michael Chabon filed a federal lawsuit in San Francisco alleging OpenAI included their writing in ChatGPT's training dataset without permission, arguing the system can summarize and mimic their works. The lawsuit seeks unspecified damages and an injunction against the alleged unlawful practices. This is the third proposed copyright-infringement class action against OpenAI, with similar suits also filed against Microsoft, Meta, and Stability AI, while the companies defend the practice as fair use. For financial institutions, this marks escalating legal and balance-sheet risk for AI vendors around training-data provenance, which may force documentary cost increases or procurement constraints.
