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)

The analysis, cited in court filings, suggests that roughly 0.7% of the logs contain substantive overlap with published news content.
