Epoch AI researchers debate: inability to find slow-improving tasks is evidence of acceleration

Jsevillamol · x · 2026-11-06

Researchers affiliated with Epoch AI are debating whether AI progress is genuine acceleration or a measurement artifact. Jsevillamol argues that if you used to be able to construct task distributions where AI improves slowly and can no longer do so, that itself counts as acceleration.

He adds that in scenario A, A-type benchmarks don't saturate, while in scenario B they do — so absent adverse benchmark selection, observed acceleration is evidence that A-type benchmarks are all saturating. TheDavidSJ counters that the subjective feeling of speedup comes from the choice of task suite, which is the only difference between the two scenarios.
