OpenAI has temporarily suspended new subscriptions and upgrades for its top-tier 200 US-Dollar monthly ChatGPT Pro plan, known as Pro 20X, due to infrastructure strain caused by demand for the newly launched GPT-6 Astra model.
OpenAI product lead Thibault Sottiaux warned on the social platform X that the Pro plan places the heaviest burden on the company’s systems, forcing the company to throttle access. According to TechCrunch reporting from September 10, 2026, the temporary freeze applies directly to anyone attempting to buy into the tier for the first time. Existing Pro 20X subscribers, however, retain full access to their accounts.
Infrastructure Bottlenecks and Tier Stratification
Launched on September 3, 2026, GPT-6 Astra rolls out across multiple service levels, including Pro, Plus, Enterprise, Business, and the developer API. The model was promoted as an advancement in reasoning, coding, and the use of computer tools.
The decision to slam the brakes on new sign-ups marks an attempt at capacity management. As analyst Chopra noted in coverage by CIO.com, capacities in the high-end range are being rationed. OpenAI has not specified when the temporary pause will lift or how many daily sign-up requests were made.
The tiered subscription architecture currently breaks down as follows:
- Plus Plan: 20 US-Dollar per month (sourced from techzine.eu)
- Pro Plan (5x limit): 100 US-Dollar per month (sourced from techzine.eu)
- Pro 20X Plan (20x limit): 200 US-Dollar per month — Currently closed to new sign-ups (sourced from TechCrunch and CIO.com)
Industry-Wide Compute Rationing Among AI Giants
OpenAI is not alone in hitting hardware limits. Rival AI lab Anthropic is also limiting the use of its Max plans. According to techzine.eu, Anthropic’s model, Claude Fable 5/5.1, currently runs at only half its regular usage limits on Max plans.

Adjustments, such as increased limits for OpenAI’s Codex coding tool last month, may have additionally increased utilization.
Workarounds for Power-Users and Developers
For engineers and power users locked out of the Pro 20X tier, options remain. The intermediate 100 US-Dollar Pro plan remains open to new subscribers, offering a 5x usage limit compared to standard accounts. Alternatively, developers can access underlying capabilities via the API.
Thibault Sottiaux described halting top-tier registrations as the smallest possible step to ensure the widest possible access to the services. Until additional capacity is added, anyone looking to purchase the 200 US-Dollar tier will have to wait out the freeze.
