METR Time Horizons

Choose a shared evaluation protocol to compare model scores. Versions, sources and configurations stay separate.

Atlas snapshot captured 10/19/2026, 10:20:28 AM UTC. This is an import timestamp, not the evaluation date. Coverage may be incomplete.

Reviewed recommendation and limits

Use as a historical reference for task difficulty measured in human completion time.

Historical time horizon at 50% success, primarily software/ML/security tasks. Imported groups below may use different protocols; this review does not certify each run. Not actively updated after September 8, 2026. Results above 16 human-hours are unreliable for this suite.
