TLDR
OpenAI paused new sign-ups to its $200-a-month ChatGPT Pro plan on 10 September 2026, citing infrastructure strain from GPT-6 Astra demand. Existing Pro subscribers keep full access. Australian businesses locked out of the tier will find rivals ready to fill the gap.
KEY TAKEAWAYS
The pause and who it hits
New sign-ups and upgrades to OpenAI's $200-a-month ChatGPT Pro plan stopped on 10 September 2026. The pause covers only the $200 tier; Plus, Business, Enterprise and the API remain open to new customers without any interruption.[1] Existing subscribers are unaffected.
GPT-6 Astra is the trigger. OpenAI launched Astra on 3 September 2026, rolling it out first to select organisations before making it broadly available to Pro, Plus, Business, Enterprise and API users.[2] The model's compute demands at the $200 tier proved sharper than OpenAI's infrastructure could absorb at volume.
Thibault Sottiaux, OpenAI's head of product, flagged the problem a day before the pause landed. On 9 September he said demand for Astra was putting a first strain on OpenAI's systems, and that a pause on new Pro subscriptions was likely if the pressure continued.[3]
To make sure our current users have an incredible experience and continued access to Astra, we are going to pause subscriptions to our $200 Pro plan. These put the most strain on our systems and we wanted to take the smallest step that allows us to continue giving the broadest access possible. All other plans and the api remain available. There is no impact to existing accounts and we are working on adding more capacity as fast as we can. Thanks!
2026-09-10 · View on XSottiaux framed the pause as the smallest possible intervention. "These put the most strain on our systems and we wanted to take the smallest step that allows us to continue giving the broadest access possible," he said.[1] He added that existing accounts face no impact and that the company is "working on adding more capacity as fast as we can."
What Australian operators should do now
OpenAI has given no timeline for lifting the pause. Any Australian business or development team planning to onboard Pro for high-volume, compute-intensive work is now modelling a rollout around an unknown date.
Teams with immediate capacity needs should check whether Plus, Business or Enterprise tiers cover the workload, or route through the API where pricing scales to actual usage. Anthropic, Google and Mistral are all currently accepting customers at their top subscription levels, and OpenAI's pause hands each of them a clean opening to lock in enterprise deals that would otherwise have landed with Pro.
