If you pay for ChatGPT Pro or Business and you also build with the OpenAI API, OpenAI just handed you a reason to stop paying twice. Announced on October 28, 2026, eligible Pro and Business subscribers can now claim up to $500 a month in OpenAI API credits — the Pro credit equals your tier price, and Business seats pool together up to a $500 workspace cap. It is genuinely useful, and it is also fenced in with expiry dates, eligibility checks and exclusions that will catch plenty of people out. Here is the whole picture, honestly.
Disclosure: no affiliate links in this article. I have not tested the credit claim myself — the facts below are OpenAI's claims from its October 28, 2026 announcement via @OpenAIDevs and its updated Help Center, not independently verified results.
What you actually get
Pro: credit equal to your tier. ChatGPT Pro subscribers get monthly API credit matching their tier price — $100, $200 or $500 per month, up to the $500 cap. If you are on the top Pro tier, that is $500 a month of API usage bundled into a subscription you were already paying for.
Business: seats pool together. ChatGPT Business workspaces pool $20 per paid Standard seat and $100 per paid Premium seat, capped at $500 per workspace per month. A small team on Premium seats hits that cap fast; a Standard-seat workspace needs 25 paid seats to reach it. Either way, the credit lands at workspace level, not per person.
What the credits fund. The credits pay for API use — OpenAI's docs coverage includes the Responses API, the Agents API, Realtime/GPT-Live and the Images API. That is the practical core of the offer: prototypes, agents, voice and image features you would otherwise fund from a separate API balance.
The catches, stated plainly
They expire — every month. Credits expire at the end of each billing cycle, with no rollover. Unused credit does not stack, and the first grant may be prorated depending on when you claim. This is a use-it-or-lose-it monthly allowance, not a growing balance. If your API usage is sporadic, set a reminder to actually spend it — or accept that some months it will simply vanish.
They don't extend ChatGPT. The credits fund API use only. They do not raise your ChatGPT usage limits, and they do not cover Codex via account sign-in. If your frustration is hitting ChatGPT's limits, this announcement does not fix it — it fixes the other bill, the API one.
Eligibility is strict. Your subscription must have been active for at least 7 days. You must own the subscription or workspace, and you must own the API organisation receiving the credits. The same email has to be on both accounts, and the credits map to exactly one linked API organisation — you cannot split them across orgs. If your ChatGPT account and your API account live under different emails, sort that out before you claim, or expect the claim to fail.
Whole tiers are excluded. Plus subscribers are out. Free trials are out. Enterprise, Edu and legacy Codex seats are out. This is a Pro and Business offer, full stop — and if you are on Plus hoping for a slice, there isn't one here.
How to claim
Claim through ChatGPT's billing settings, or through the OpenAI Developers plugin in ChatGPT or Codex. The practical advice: claim as soon as you are eligible, because the monthly clock — and the expiry — starts with your billing cycle, not with your enthusiasm. And before you build anything that depends on the credit, confirm it actually landed in your API organisation: a claim that looks successful in ChatGPT but never reaches the right org is worthless until you verify it.
What this does not mean
First, this is not OpenAI making the API free. $500 a month is generous for experiments, prototypes and small production workloads, but a serious production app will burn through it — and then you are back on paid API billing, exactly as before. Treat it as a subsidy, not a replacement.
Second, availability may vary by country. OpenAI's announcement does not guarantee identical availability everywhere, so if the claim option does not appear for you, regional availability is the first thing to check — not a bug in your account.
Third, we have not tested the claim ourselves. Everything above is OpenAI's stated terms as announced on October 28, 2026. Real-world friction — how smooth the linking is, how proration actually works on the first grant, whether seats pool exactly as described — will only show up once subscribers start claiming.
What to do this week
- If you are on Pro: check your tier, claim the matching credit ($100, $200 or $500), and move one experiment or side project off your paid API balance onto the credit — that is the fastest way to feel the saving.
- If you run a Business workspace: work out your pooled cap from your seat mix ($20 Standard, $100 Premium, $500 ceiling) and decide as a team what the credit funds — one shared prototype beats five people each forgetting their share expires.
- If your emails don't match: align your ChatGPT and API accounts to the same email and confirm you own both before you claim — the one-organisation rule means a wrong link wastes the grant.
- If you are on Plus: don't wait for this offer to trickle down — it is explicitly Pro and Business only, and upgrading just for the credit only makes sense if you would actually spend $100+ a month on the API anyway.
- Whatever you do: remember the expiry. A monthly credit you forget is a monthly credit you never had — put the billing-cycle end date somewhere you will see it.
What we don't know yet
- Real claim friction: how smooth the linking and claiming flow is in practice, and how first-grant proration is calculated, is not yet confirmed by independent reports.
- Country-by-country availability: OpenAI has not published a full availability list, so regional differences remain unconfirmed.
- Whether the offer changes: no end date or revision timeline has been stated — the terms above are the launch terms, and they could move.
None of that takes away from the headline: OpenAI just bundled up to $500 a month of API usage into subscriptions many developers already pay for. The developers who benefit most will be the ones who claim early, verify the credit landed in the right organisation, and actually spend it before the billing cycle eats it. The rest will read about it next month and wonder where their $500 went.
