METR Doubling as Capability Metric

Track the maximum duration of tasks an AI can autonomously complete (METR); rapid reductions in METR doubling time signal qualitative leaps in autonomous competence beyond incremental benchmark gains. Using METR as a standard metric lets policymakers and firms quantify how fast systems move from short, discrete automations to long, end‑to‑end autonomy. — If METR halves or its doubling time shortens dramatically, regulators, energy planners, labor markets and national security agencies should treat that as a near‑term trigger for escalated oversight and contingency planning.
