ChatGPT API credits are now a real perk of paying for ChatGPT Pro or Business. Since October 28, 2026, eligible subscribers can claim up to $500 a month in free API credit, OpenAI announced. You claim it in your billing settings, and whatever you don’t spend expires at the end of the cycle.
Here’s the short version before we get into the details.
- Announced: October 28, 2026, by OpenAI Developers
- Who gets it: eligible ChatGPT Pro and Business subscribers
- Size: up to $500 a month, depending on plan and seats
- Catch: credits expire each billing cycle and don’t roll over
If you already pay for one of these plans and build anything with the API, this is basically free money. If you don’t, there’s nothing to do.
Who gets ChatGPT API credits, and how much?
The amount depends on your plan. Pro subscribers get credit that matches their tier, while Business workspaces get a per-seat amount that pools across the team.
| Plan | Monthly API credit | Notes |
|---|---|---|
| ChatGPT Pro | $100, $200, or $500 | Depends on your Pro tier |
| Business Standard seat | $20 per paid seat | Pooled across the workspace |
| Business Premium seat | $100 per paid seat | Workspace total capped at $500 a month |
Plus, Go, and Free plans aren’t mentioned in the announcement. According to ExplainX, they’re excluded, along with Enterprise and free trials. OpenAI’s own post points to its Help Center for the full eligibility rules, so check there if you’re on the edge.
How to claim your ChatGPT API credits, step by step
OpenAI says you claim the credit from ChatGPT billing settings, then create an API key with the OpenAI Developers plugin in ChatGPT or Codex. In practice, it looks like this.
- Sign in to ChatGPT as the subscription owner.
- Open billing settings and find the API credits benefit.
- Pick the API organization that should receive the credit, then confirm.
- Create a project API key and use it for your requests.
ExplainX reports a few extra conditions: the subscription must be at least seven days old, you must own both the ChatGPT plan and the API organization, and both accounts need the same email address. Treat those as likely, not official, until you see them on OpenAI’s Help Center page.
What the credits don’t cover
The fine print matters here, because “free API credit” sounds broader than it is. A few limits stand out.
- Credits expire at the end of your billing cycle. A community reply on OpenAI’s forum says the first grant is prorated.
- They don’t raise your regular ChatGPT or signed-in Codex usage limits.
- Codex usage through API keys isn’t supported, according to a quote from OpenAI in the ExplainX write-up.
The last point is the one people will trip over. If you planned to power Codex through an API key with these credits, plan again.
When the balance runs out, ExplainX says requests fail with an HTTP 429 error and the code credit_balance_exhausted. Free credit is used before any money you’ve added yourself.
Who benefits most from the new API credit?
Developers and small teams get the most out of it. If you’re prototyping an app, running scripts against a model, or testing agents, a few hundred dollars of monthly usage goes a long way.
It pairs well with the agent-style tooling that’s been landing lately. We covered how the Cursor Agent SDK lets you build coding agents as plain code, and the same kind of project can now run on credit you’re already paying for. If you’re curious about longer-running agents, our explainer on OpenAI Dots is a good next read.
Casual ChatGPT users won’t notice any change. The credit only matters if you call the API.
Smart ways to use up your monthly credit
Since nothing carries over, the goal is simple: spend it before the cycle ends. A little planning helps.
- Move your lightweight scripts and side projects to the new credit first.
- Keep production workloads on a separate project, so a drained balance never breaks a live app.
- On a Business workspace, tell your team who owns the API organization, since the owner is the one who claims.
The reason to split projects is the 429 error above. A quiet end-of-month failure is much easier to avoid than to debug at midnight.
Also check your spending dashboard after the first week. Seeing how fast the credit drains tells you whether $100 is plenty or $500 barely covers your workload, and that is useful when you decide which Pro tier is worth keeping.
Frequently Asked Questions
Are ChatGPT API credits really free?
They’re included with an eligible paid Pro or Business plan, so you don’t pay extra to claim them. You still pay for the subscription itself.
Do unused credits roll over to next month?
No. Reports say they expire at the end of the billing cycle, so claim and use them each month.
Can I use the credits for Codex through an API key?
No. Codex usage through API keys is reported as not supported by this benefit. The credits also don’t raise your normal ChatGPT or Codex limits.
Do ChatGPT Plus subscribers get API credits?
Not at launch, as far as the announcement and early reports show. OpenAI hasn’t said whether Plus will be added later.
Should you claim your ChatGPT API credits?
Yes, if you build with the API even occasionally. It takes a few minutes, costs nothing, and offsets real spending. Just set a monthly reminder, because the credit disappears if you don’t use it. If you only chat in the app, skip it and carry on.
