AI models' human-equivalent time horizons scale sub-linearly with tokens, per UK AISI

Toby Ord highlights a chart from UK AISI showing that recent AI models' human-equivalent time horizons scale sub-linearly with tokens — more training yields diminishing gains in how long tasks models can handle.

He adds that finer-grained human measurements suggest the human curve bends upwards rather than downwards in that range, an important reference point for model-vs-human scaling comparisons.
