GPT-6 Astra: The Next Generation in Intelligence for Work
OpenAI, Wednesday, September 9th, 2026
OpenAI's most capable business model adds advanced reasoning, computer use and stronger writing and design judgment.
OpenAI introduced GPT-6 Astra, positioned as its most capable model for business use, with advanced reasoning, computer use and improved writing and design judgment.
The launch is notable beyond capability claims because OpenAI's Preparedness Framework classified Astra as Critical for cybersecurity, the first commercial model at that level, which restricts access to some functions.
Demand subsequently strained capacity enough that OpenAI paused new signups to its highest Pro tier.
Organizations evaluating Astra should plan for both the capability and the access restrictions that accompany it.
