A reported $500-per-month ChatGPT plan called Pro Max would sit above OpenAI’s existing Pro subscriptions. The strongest clue is wording found in unreleased subscription references: “Fastest Work and Codex.” That suggests a plan aimed at demanding work and coding tasks, but it is not a product announcement or a confirmed promise of specific performance. 26
What the leak actually shows
TestingCatalog reported the unreleased subscription references on September 24, 2026. A separate account also credits researcher Tibor Blaho with spotting backend references. TestingCatalog says the references show a $500 monthly price and the “Fastest Work and Codex” description; it treats higher usage limits as a possibility, not a confirmed feature. 26

That distinction matters for heavy users. ChatGPT Work and Codex currently share usage limits, so a plan that raised those limits could help people who regularly run into them across either service. But the leaked wording emphasizes speed, and no Pro Max allowance, rate limit or measured speed advantage has been established. 18

How it compares with Plus and Pro
OpenAI lists Plus at $20 per month. Its Pro options are $100 per month for 5× Plus usage and $200 per month for 20× Plus usage. At the reported price, Pro Max would cost 2.5 times as much as Pro $200—but there is no basis yet for assuming it would provide 2.5 times the usage or any particular speed increase. 12

There is also an availability wrinkle. Since September 10, OpenAI has temporarily paused new sign-ups and upgrades to Pro $200. Existing $200 subscribers are unaffected, and the $100 Pro option remains available. OpenAI cited capacity strain amid demand for its Astra model; that makes the timing of a potentially more demanding plan uncertain, but does not establish whether or when Pro Max will launch. 3

Could faster inference infrastructure be involved?
There is a plausible lead, not a confirmed connection. OpenAI describes an Ultrafast API preview for GPT-5.6 Sol, while Cerebras says it runs that mode at up to 750 output tokens per second on its hardware. TestingCatalog raises Cerebras as a possible explanation for the leaked “Fastest” language. Neither the API preview nor that speed figure establishes what a ChatGPT Pro Max subscriber would receive. 17

For now, the $500 price and “Fastest Work and Codex” wording are reported findings from unreleased references. OpenAI has not confirmed Pro Max’s final price, benefits, limits, launch date—or that it will launch at all. 26
