haider1 · x · 2026-09-09

A widely shared comparison claims GPT-6 Astra has an estimated p80 task horizon of 11.6 hours — meaning 80% success on tasks taking a skilled human 11.6 hours — closely tracking the 18.6-hour level implied by AI-2027's September 2026 curve.

The thread notes AI-2027, once mocked as too aggressive, has landed almost on target: task horizons went from 30 minutes to an estimated 16 hours in barely over a year, with the curve still accelerating. Figures are unverified estimates, not official OpenAI numbers.
