Responding to backlash over limiting what METR could publish in its risk report, an Anthropic cofounder said: "We redacted a lot, and I accept that this makes it harder for others to check METR's work. But we determined that sharing exactly what is driving the speedup isn't the right thing to do."

Gary Marcus commented "not a good look," joining criticism that safety is being used to justify limiting external verification.
