Microsoft court filings: an expert hired by publishers found that only ~60K of 8.2M Copilot chat logs contained at least 16 words in common with news content (Lauren Feiner/The Verge)

Microsoft court filings reveal that an expert hired by publishers found a minimal overlap between Copilot chat logs and news content. Out of 8.2 million Copilot chat logs, only approximately 60,000 contained at least 16 words in common with news content. This indicates that fewer than 1 percent of the chat logs reproduced a significant portion of news content, suggesting that Microsoft's Copilot rarely regurgitates such material.
