trailDoubling time, in days, of the 50%-task-completion horizon of frontier AI models released from 2024 onward on METR's software task suite
The task-completion time horizon of frontier AI models began growing faster around 2024.
AI agents’ 50%-reliability software-task horizon will continue doubling approximately every seven months.
The argument from suite saturation
METR Time Horizon 1.1's 50% time horizons above roughly 16 human-hours are unreliable measurements.
atomic
assumed
Frontier AI 50% time horizons on METR's task suite have grown approximately exponentially with release date since 2024.
assumed
METR's human baseline times reliably measure the length of its software tasks.

claimA box is a claim: a single proposition the graph assesses, with its own page and map. Click any claim to centre the map on it.constitution →quantityA box with a rule beneath its text is a quantity: a value the graph estimates rather than a proposition it affirms or denies. Its estimate stands where a claim's status would.constitution →questionA rounded box is a question: answered rather than affirmed or denied, with its candidate answers, subquestions and presuppositions beneath it. Its mark says how well answered it is.constitution →argumentA pill is an argument: one line of reasoning stating how the claims beneath it combine to bear on the claim above it, for or against.
