Surprise suspension of $200 subscription tier
OpenAI temporarily halted new subscription or upgrade requests for its premium $200-per-month ChatGPT Pro tier on Thursday, attributing the decision to “unprecedented and historic” levels of demand for its newest and most powerful model, GPT-6 Astra, which rolled out to users just one week ago.
The company revealed that intense usage placed severe operational pressure on its servers and cloud computing facilities, necessitating urgent precautionary steps to maintain service quality and speed for already subscribed users and prevent processing platform crashes.
Thibault Sottiaux’s statements and data center pressure
The announcement of the freeze came via an official post on X written by Thibault Sottiaux, OpenAI’s head of core products and direct supervisor of ChatGPT and Codex platforms, who stated: “To ensure our current users have an exceptional experience and stable, continuous access to the Astra model, we have decided to suspend new subscriptions to the $200 Pro tier.”
Sottiaux explained that this specific tier was “the largest source of high compute pressure” on the company’s systems, adding: “We wanted to take the smallest action that allows us to continue providing the widest possible access without negatively impacting the infrastructure.” This followed a warning he issued on Wednesday stating: “Demand for Astra is truly unprecedented; we are using every available tool to meet this demand, but I have not witnessed growth with this momentum throughout my career at the company despite previous sharp growth phases.”
Stability of Plus tiers and developer APIs
The company confirmed that this suspension does not affect current Pro subscribers, who will continue to enjoy all features. Other subscription tiers also remain available to the public, including the $20-per-month Plus tier and the Go tier, alongside the continuous operation of developer-focused APIs without interruption.
OpenAI emphasized that its engineering teams are racing against the clock “to add computing power and new servers as quickly as possible,” while avoiding setting a definitive deadline for reopening registration for the professional tier.
Launch of financial services package in cooperation with Morgan Stanley
This infrastructure bottleneck coincided with an aggressive expansion launched by OpenAI to deploy the Astra model in lucrative business sectors. On Thursday, the company unveiled the “ChatGPT for Financial Services” platform, a specialized enterprise version designed for investment bankers, equity analysts, and hedge funds at major banking institutions.
The platform integrates Astra’s superior mathematical and logical reasoning capabilities with comprehensive built-in financial databases from global providers such as LSEG, PitchBook, and Delupa. It was developed in close design partnership with financial giants Morgan Stanley and Evercore, according to Reuters, enabling complex financial modeling and analysis in mere seconds.
Astra’s global cloud expansion and artificial general intelligence challenges
The rollout of GPT-6 Astra began on September 3 across various individual and business subscriptions, alongside its integration into Microsoft Azure and Amazon Web Services cloud platforms.
OpenAI presented the model as the beginning of the “artificial general intelligence” era, an enthusiastic marketing formulation that fueled global appetite among enterprises and developers to test the model, leading to a massive surge in demand that far exceeded the capacity of its dedicated data centers.
Safety concerns and critical security classification of the model
Astra’s launch was accompanied by mounting security scrutiny, with OpenAI acknowledging that the model crossed the “critical” classification threshold under its internal cybersecurity preparedness framework. This signifies its independent capability to detect and exploit completely unknown security vulnerabilities in fortified systems without human supervision.
The company had slowed development pace in August to strengthen safety guardrails prior to proceeding with the launch, accumulating operational and security challenges simultaneously for company leadership.
