OpenAI's ChatGPT Pro Max subscription, priced at $500 per month, has surfaced inside the platform's subscription interface, featuring "Fastest Work and Codex" access, 100GB of file storage, and the company's most capable frontier models.
OpenAI is developing a new ChatGPT Pro Max subscription tier priced at $500 per month, according to subscription interface screenshots surfaced by researchers — a plan that would more than double the cost of the company's current top-tier offering.
The unannounced plan, first reported by BleepingComputer, has begun appearing inside ChatGPT's subscription interface alongside existing Plus and Pro options, though OpenAI has not confirmed a launch date or formally announced the tier.
One version of the interface lists Pro Max at $500 per month, while another shows $600 after local taxes or VAT are applied, according to screenshots attributed to the account TestingCatalog on X.
The plan's described features include access to what OpenAI calls its most capable frontier models, maximum memory, 100GB of file storage, and early access to new features. The most prominent differentiator listed in OpenAI's own interface language is "Fastest Work and Codex."
OpenAI currently offers Pro tiers at $100 and $200 per month. New sign-ups and upgrades to the $200 plan have been temporarily paused since September 10, the company has said.
Power users have sought higher usage allowances than the $200 plan provides, signaling demand for a tier positioned above the existing options. OpenAI has not disclosed what usage limits, if any, Pro Max would carry.
The "Fastest Work and Codex" language has drawn attention to the possible role of Cerebras hardware in the new tier. OpenAI has been deploying Cerebras chips for high-speed AI inference — earlier this year, Codex-Spark launched on Cerebras at more than 1,000 tokens per second, and OpenAI demonstrated GPT-5.6 Sol running at up to 750 output tokens per second in a Cerebras-powered Ultrafast mode. Neither OpenAI nor Cerebras has confirmed any connection between Cerebras infrastructure and the Pro Max plan.
The $200 Pro plan also promises early access to new features, leaving open the question of whether that benefit would be curtailed or redirected exclusively to Pro Max subscribers at launch.
With exact usage limits, a launch timeline, and infrastructure details still undisclosed, the plan's full scope remains unclear — though its appearance in live product interfaces suggests a rollout could be approaching.
