Microsoft says Copilot rarely reproduces full news articles, filings show

In discovery for publishers' copyright lawsuit, Microsoft handed over 8.2 million Copilot chat logs selected for likely use of the plaintiffs' content. Microsoft says its analysis shows the chatbot rarely reproduces substantive chunks of the original articles.

Why it matters: This mirrors the defense OpenAI is making in its own New York Times suit: that outputs rarely resemble originals closely enough to count as infringement. A ruling in either of these overlapping cases will set precedent affecting nearly every consumer chatbot built on scraped news content.
