OpenAI Turns Pro Subscription Fees into API Credits, Leaving Plus Users Out

On October 28, OpenAI announced that paid ChatGPT Pro and Business subscriptions can claim a monthly API credit allowance of up to $500 at no extra charge. Plus does not get it.

APIs are the interfaces used by developers; when your own app, website, or automation script calls OpenAI models, it goes through this path. Previously, ChatGPT subscriptions and the API were two separate accounts: even after paying the subscription fee, writing programs still required topping up separately. Now this credit is counted as part of the subscription, merging the billing one layer further.

Who can get it, and how much

Pro gives it by tier: $100, $200, and $500. According to CellCog, the credit is exactly equal to the monthly fee of each tier, turning the subscription fee into API credits as-is. Business is calculated by paid seat: standard seats are $20 each, premium seats are $100 each, and the entire workspace pools usage, capped at $500. It maxes out at 25 standard seats or 5 premium seats, and adding more people does not increase it.

Plus, Go, Free, and Enterprise do not get it. Subscriptions must also be at least 7 days old; free trials and gifted subscriptions do not count. The official tweet did not mention regional restrictions, and neither media outlet wrote about them. The claim entry point is in ChatGPT's "Settings → Billing"; link an API organization under your own name, and use the same email for the ChatGPT account and the API account. For Business, a workspace admin claims it in billing settings or the admin console. After claiming, use the OpenAI Developers plugin in ChatGPT or Codex to generate an API key and create a project, without needing to bind a credit card first.

What it can be used for, and what it cannot pay for

This money can be spent on most services on the OpenAI developer platform: calling models for conversations and agents, real-time voice, image generation, and built-in tools such as web search and the code interpreter. Building a small tool for yourself or an internal Q&A bot for your team both count as intended uses.

The limitations should also be clear. The credit is valid for the current month and resets to zero at the end of the billing cycle; it cannot be saved for the next month, and the first month is prorated by remaining days. Running Codex with an API key cannot spend this credit; it also does not raise usage limits in ChatGPT and Codex—the two sides' credits are calculated separately. Spending order is gifted credit first, then your own top-up; once both are used up, requests will directly error unless auto-recharge is enabled. An annually paid Business workspace is given the full year's credit at once, capped at $6,000; the first month is prorated by the remaining cycle, and it also resets to zero upon expiration.

Baoyu reminded in the tweet that the first month is prorated, and his credit this month is only $75. Before claiming, check the amount shown in billing.

Some netizens said in replies that this looks like Claude's playbook; others said free API credits are the oldest land-grab by cloud vendors. For Pro users, this credit can cover small scripts, image generation, and internal tools, and resetting to zero at month-end will push people to find work to do. Some netizens reminded people to confirm auto-recharge is off before claiming, otherwise the budget wall disappears. Plus users' dissatisfaction is more direct: they pay the subscription fee but are not on the list.

The rules are subject to the OpenAI Help Center. The original OpenAI Help Center page was previously unstable to access; details beyond the tweet come from AlphaSignal's and CellCog's paraphrases of the help page.

The value of this credit is not in the number itself, but in OpenAI erasing another layer of the boundary between subscriptions and APIs. For people writing small tools, it is a real offset; for heavy Codex users, it is not a universal coupon. First check eligibility, then check the actual amount in billing, and finally decide whether to keep the subscription.
