Anthropic Defends Redacting Majority of Evidence in AI Speedup Report
From marketbrief.now
AI;DR
Anthropic co-founder Sam McCandlish defended the lab's decision to redact most of the data from an independent safety assessment of its research pace, citing commercial sensitivity and industry risks. The audit by METR estimated that Anthropic's capabilities are growing at roughly twice the rate measured between March 2024 and October 2025, with internal AI tools driving about 80% of that acceleration. Because the public version of the report was heavily redacted, METR stated that the public must rely on the evaluators' subjective judgment rather than the underlying evidence.
