## In short

Wes Roth walks through METR's independent assessment of AI R&D acceleration at Anthropic, why much of the audit was redacted, and what the AECI benchmark trend says about the pace of Claude's progress.

## What it is

'Anthropic just built it...' went up on Wes Roth's channel on 6 November 2026. The video covers METR's assessment of AI R&D acceleration at Anthropic, published on 5 November, and METR's review of the R&D section of Anthropic's August 2026 risk report.

## How it works

Chapters start with the redacted audit, then move to the '2x safety line', the AECI benchmarks, the trend inflection, the researcher interviews and compute allocation. Roth links the METR posts, Anthropic Institute pieces on recursive self-improvement and on measuring the pace of AI development, and comments from Daniel Kokotajlo and Sam McCandlish.

## Why it matters

METR's report is the first outside estimate of how much AI speeds up research at a frontier lab, and the video gives a quick guided reading for viewers who will not read the METR posts themselves.

## Who it's for

people following AI safety and frontier-lab progress
