Which ChatGPT plans get Astra?
OpenAI announces a staged GPT-6 Astra rollout, starting with a limited set of organizations and expanding over the coming days to all ChatGPT Plus, Pro, Business and Enterprise users. Usage is included within existing subscription allowances, with credits available to purchase for additional usage.
Pro, Business and Enterprise users also get GPT-6 Astra Pro. Enterprise administrators can enable Astra for their workspace, but access is off by default at launch.
API prices and Fast mode
OpenAI lists Standard API pricing at $10 per million input tokens and $50 per million output tokens. Separate rates apply to cache reads and writes.
API Fast mode costs twice the Standard price and offers up to twice the processing speed. These are API pricing terms, separate from the announcement's ChatGPT subscription allowances.
