Background & analysis
On November 5, 2026, METR released an independent assessment of Anthropic's AI R&D acceleration in October 2026. Under METR's transparency approach, METR says it had the right to disclose whether Anthropic exercised redaction rights and whether any of METR's findings depended significantly on redacted information. METR states that it was able to freely share its highest-level conclusions about risk, but that Anthropic redacted a majority of the evidence METR found most informative for those conclusions. The two parties disclosed the scope of the redactions as agreed. At this point, METR's highest-level risk conclusions have been published and were not affected by the redactions, while a majority of the most informative evidence remains redacted. Any remaining disagreement concerns whether the redacted information significantly affected the findings, and the two sides have described their positions accordingly.

Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
