Calendar year in which artificial general intelligence is first developed
Artificial general intelligence will be developed by 2028.
Extrapolating exponential AI capability trends is a sound basis for short AI timelines.

Doubling time, in days, of the 50%-task-completion horizon of frontier AI models released from 2024 onward on METR's software task suite
METR Time Horizon 1.1's 50% time horizons above roughly 16 human-hours are unreliable measurements.
Frontier AI 50% time horizons on METR's task suite have grown approximately exponentially with release date since 2024.
Benchmarks beyond METR's software suite show AI time horizons or capabilities growing faster since 2024.

The argument from measurement artifacts· against
METR's apparent post-2024 time-horizon acceleration reflects measurement artifacts rather than faster AI capability growth.
atomic
assumed
METR's human baseline times reliably measure the length of its software tasks.
