This claim is contradicted by OpenAI’s own availability notices.

On the same date as this post (September 3, 2026), OpenAI’s launch page said GPT‑6 Astra was "rolling out today to a limited set of organizations" and would become available over the coming days to ChatGPT Plus, Pro, Business, and Enterprise users, as well as through the API. That means it was not something “anyone” could immediately use just by going to talk to it.

OpenAI’s current Help Center documentation is also narrower than “anyone can just go and talk to it.” It says GPT‑6 Astra is available in ChatGPT for Pro $100, Pro $200, Business, and Enterprise plans, while Plus users get Astra only in ChatGPT Work and Codex. The same help article adds that ChatGPT Work is gradually rolling out and that eligible accounts may not have access yet.

So the post’s wording is too broad in two ways:

1. At the time of posting, Astra was not open to everyone; OpenAI said it was limited at launch.
2. Even after rollout, access is tied to specific products/plans and in some cases workspace permissions or rollout status, not to “anyone” in general.

A more accurate formulation would be that Astra was being released commercially/publicly, but with plan and rollout restrictions, rather than being universally available to anyone.
