Autonomous task horizons are lengthening

METR proposes measuring agents by the duration of human work they can complete at a stated success rate. Its longitudinal results show rapid growth in the length of software tasks frontier systems can finish under test conditions.

What the evidence indicates

A concise reading of the source

METR proposes measuring agents by the duration of human work they can complete at a stated success rate. Its longitudinal results show rapid growth in the length of software tasks frontier systems can finish under test conditions.

FUURAA interpretation

Why this could matter

Task duration offers a more operational signal than isolated question answering, but it remains dependent on benchmark design and success thresholds.

How to read this signal

Documented development

The underlying event, report or finding has been published. Its future consequences may still be uncertain.
