## Summary

METR reviewed the automated R&D section of Anthropic's August 2026 Risk Report. It agrees that July 15 models posed low catastrophic risk, but says they plausibly crossed the early-warning threshold for 2x acceleration. METR argues the public report understates the evidence for acceleration in leading indicators and AECI.

## Why it matters

The review shows where METR disagrees with Anthropic's public risk report and why the early-warning call rests on contestable judgments.
