OpenAI’s top Pro subscription now costs $500 a month. The new Pro 500 tier includes Astra Ultrafast and what OpenAI describes as its highest Pro usage allowance. Meanwhile, a new subscriber to the $200 Pro 200 tier gets a lower allowance than an eligible existing subscriber can temporarily retain.
The comparison is more complicated than a choice between $200 and $500. A Pro 200 account’s allowance depends on whether it qualifies for grandfathering. OpenAI’s advertised Ultrafast speeds are also up to figures, not a promise that every task will run that much faster. The available details do not establish how credits would be drawn after included usage runs out.
The Three Pro Prices Do Not Tell the Whole Story
OpenAI’s Pro tier guide lists three monthly subscriptions:
| Plan | Monthly price | Usage and speed distinction |
|---|---|---|
| Pro 100 | $100 | Lower-priced Pro option; the cited tier details do not establish a numerical allowance for this comparison |
| Pro 200 | $200 | New subscriptions have a lower allowance than eligible grandfathered subscriptions |
| Pro 500 | $500 | Highest allowance, described by OpenAI as 25 times Plus; the only listed Pro tier that includes Ultrafast |
The table’s gap is deliberate. OpenAI’s DevDay 2026 recap gives a relative figure for Pro 500, but the verified details here do not provide comparable numerical allowances for Pro 100 and Pro 200. Neither plan’s capacity can be inferred from its price. Paying two and a half times as much as Pro 200 does not necessarily buy two and a half times its allowance.
Moving from Pro 200 to Pro 500 adds $300 per month. Whether that pays off depends on the work a subscriber runs and how often they reach their existing limits. A headline allowance expressed as a multiple of Plus cannot tell a particular user how many coding sessions or other jobs they will complete.
The October 29 Cutoff Applies to Eligible Pro 200 Subscribers
For current users, the immediate question is whether their Pro 200 subscription has the older allowance. OpenAI says eligible subscribers can retain it until October 29, 2026, provided their subscription remains active. New Pro 200 subscriptions receive the lower allowance.
Subscribers paying the same $200 monthly price therefore have different limits for now. Someone who regularly uses enough capacity to notice the reduction should not assume their current allowance will remain available after the cutoff. A prospective subscriber should evaluate Pro 200 using the new allowance, not reports of what an eligible existing customer can still use.
The cited tier information does not establish every eligibility scenario or specify an exact changeover hour. Nor does it justify assuming that canceling and later restarting a subscription would preserve an older allowance. Anyone making a decision around the deadline should check the terms displayed for their own account rather than count on a particular limit for the entire day of October 29.
An allowance also does not translate neatly into projects completed or developer hours saved. Without the applicable usage terms and a record of their own consumption, subscribers cannot reliably turn the plan names into a personal break-even point.
Astra Ultrafast Promises a Ceiling, Not a Fixed Speedup
Pro 500 is the only one of the three listed Pro plans that includes Astra Ultrafast. In its DevDay announcement, OpenAI says Ultrafast can deliver up to eight times the token-generation speed in Codex and up to six times in the API.
Those are advertised ceilings. “Up to eight times” does not mean every Codex task will finish in one-eighth the time. A coding task may involve reading files, using tools and waiting for other steps besides token generation. The API figure likewise concerns token-generation speed, not a guaranteed reduction in end-to-end request time.
The API claim does not mean a $500 ChatGPT subscription includes API usage or covers API bills. It describes an Ultrafast speed claim in a different setting. Buyers who need API capacity should check the applicable access and billing terms separately.
Speed and allowance address different needs. A subscriber who rarely reaches Pro 200’s limits might still want faster output for time-sensitive work. Someone who routinely exhausts their allowance might place more value on capacity, even if their jobs do not approach the maximum advertised speedup. Whether either benefit is worth another $300 depends on the workload.
Open Questions About Credits and Included Usage
If work can continue after a plan’s included allowance is used, the cost of that additional work affects the comparison. Credit draw is therefore a material question.
The verified details in OpenAI’s tier guide and DevDay recap do not establish the credit-draw mechanism after included Pro usage. They do not support saying that credits are spent automatically, identifying a draw rate or promising that work will continue without interruption. They also do not establish a price at which buying credits would be preferable to upgrading from Pro 200 to Pro 500.
Before relying on a cost comparison, subscribers should confirm the terms for their account: what happens at the included limit, whether additional work requires credits or another payment, and what rate applies to their tasks. For now, the documented comparison is narrower. Pro 500 costs $300 more per month, carries OpenAI’s highest stated allowance and includes Ultrafast. Its total value relative to Pro 200 depends on the workload.
“25 times Plus” indicates how OpenAI positions Pro 500. It cannot replace the limits and billing rules a heavy user would encounter in practice.
Final Thoughts
Eligible Pro 200 subscribers are temporarily comparing Pro 500 against an older, higher $200 allowance. New subscribers are comparing it against a lower one. Using the wrong baseline could make the $300 monthly difference look better or worse than it is.
Pro 500 has a clear price, a higher stated allowance and access to Ultrafast. The unresolved purchasing questions are how much work that allowance covers, what happens when it runs out and whether Ultrafast shortens the tasks a subscriber actually runs. Its documented advantages do not guarantee a saving in time or total cost.
Frequently Asked Questions
4 questions
1How Much Do OpenAI’s Pro Plans Cost?
OpenAI lists Pro 100 at $100 a month, Pro 200 at $200 a month and Pro 500 at $500 a month. Pro 500 is the only one of those tiers listed with Astra Ultrafast. OpenAI describes its allowance as 25 times Plus, but that figure does not establish a numerical allowance for either lower-priced Pro plan.
2Who Keeps the Older Pro 200 Usage Allowance?
Eligible existing Pro 200 subscribers can keep their previous allowance until October 29, 2026, while their subscription remains active, according to OpenAI. New Pro 200 subscriptions receive a lower allowance. The cited details do not establish every eligibility scenario or an exact changeover hour, so subscribers should check the terms shown for their own accounts.
3Is Pro 500 Guaranteed to Make Codex Eight Times Faster?
No. OpenAI advertises up to eight times the token-generation speed in Codex with Astra Ultrafast, not an eightfold reduction in every task’s completion time. It also cites up to six times the token-generation speed in the API. Neither ceiling guarantees the speed a subscriber will see on a particular workload.
4What Happens When a Pro Plan’s Included Usage Runs Out?
The verified tier and announcement details do not establish the credit-draw rules after included Pro usage runs out. They do not confirm an automatic credit charge, a draw rate or uninterrupted access. Before choosing a plan on the assumption that extra usage will be affordable, check the applicable account terms for how additional work is handled and billed.
