Encyclopedia Britannica and its subsidiary Merriam-Webster have sued OpenAI, alleging copyright infringement for using their content to train AI models like ChatGPT without permission, as well as trademark infringement from the AI falsely attributing hallucinations to Britannica. The suit claims ChatGPT reproduces verbatim or near-verbatim portions, summaries, or abridgments of their works, cannibalizing traffic to their sites.
