METR chart: Anthropic employees self-report ~12x productivity uplift from Model 4
scaling01 · x · 2026-11-06
scaling01 shares a METR chart aggregating informal surveys and Slack polls of Anthropic employees on self-reported productivity uplift from internal models.
- Uplift grows superexponentially over time: from 1.3x (3.7 Sonnet, early 2025) through Opus 4.6 (2.5x) and the Mythos series (4-5x), to 12x for the latest Model 4
- An exponential fit implies 3.9x per year, with a superexponential fit even steeper
- METR cautions these are informal, self-reported results and should be treated as very loose evidence
