Encyclopaedia Britannica Sues OpenAI, Escalating a Global Copyright Clash Over AI Training Data
Encyclopaedia Britannica and MerriamâWebster have sued OpenAI in New York, alleging unauthorized copying of nearly 100,000 reference entries to train ChatGPT and claiming the AIâs outputs divert traffic and misattribute sources. OpenAI invokes "fair use" and transformative use; the case joins a wave of copyright litigation that could reshape how generative models are trained, funded and regulated.
