OpenAI begins gradual rollout of GPT-6 Astra across ChatGPT, Work and Codex
Access to OpenAI’s latest model varies by subscription, platform and workspace permissions, with usage limits differing across plans.
OpenAI began a gradual rollout of GPT-6 Astra on 3 September, extending access across ChatGPT, Work and Codex. The rollout does not guarantee immediate availability for eligible accounts, and the company has not specified when individual users will receive access.
In regular ChatGPT, Astra is presented as GPT-6 Pro and is rolling out to $100 and $200 Pro subscribers, as well as Business and Enterprise users. Free and Go users are excluded, while Plus subscribers can access Astra through Work and Codex rather than regular ChatGPT.
Availability may differ between ChatGPT, Work and Codex. Enterprise access can also depend on workspace model-access permissions, while Work availability may vary across web, mobile and desktop platforms. Codex CLI users need version 0.153.0 or newer.
Usage allowances vary by plan and task complexity. Engadget reported OpenAI estimates of roughly five to 45 local Astra messages per five-hour period for Plus users, 25 to 225 for the $100 Pro plan and 100 to 900 for the $200 tier. Chat has separate weekly limits: 50 GPT-6 Pro messages shared with GPT-5.6 Sol Pro on the $100 plan, and 200 GPT-6 Pro messages on the $200 plan.
OpenAI advises users to reserve Astra for more demanding tasks and keep prompts focused. The model is also available to developers through the API at standard rates of US$10 per million input tokens and US$50 per million output tokens. Requests exceeding 272,000 input tokens are charged at higher rates, according to the source.
