According to a link post by Simon Willison published on 29th October 2026, OpenAI has launched a benefit giving eligible ChatGPT subscribers API credits matching their subscription tier. Willison reports that subscribers on $100, $200, or $500 plans now receive the equivalent quantity of credits to apply to one of their API organizations. He writes that the offer is 'pretty much exactly the same deal' as one Anthropic announced earlier in the month for its Max and Team subscriptions, where $100, $200, and $500 subscribers receive the equivalent quantity of expiring credits for use with the Anthropic API. Willison, who maintains subscriptions with both companies, states the change is useful to him personally and notes he 'may even ship some public-facing demos now that the credits are already covered by my existing subscriptions.' The details here are drawn from a single independent source rather than a direct vendor announcement, and specifics such as whether the OpenAI credits expire are not stated in the excerpt. Readers should treat the terms as described secondhand until confirmed through OpenAI's own documentation.
- OpenAI subscribers on $100, $200, or $500 plans reportedly receive matching API credits for one API organization.
- Anthropic announced a comparable benefit earlier in the month for Max and Team subscriptions, with its credits described as expiring.
What it means for you
If your team already pays for a high-tier ChatGPT subscription and separately pays to use OpenAI's API for building things, you may now be paying twice for capacity you could get in one bill. This doesn't change what the tools do — it just means some API usage you already pay for might now be covered by a subscription you also already pay for. Anthropic offers a similar deal on its higher plans.
Try this
If you run OpenAI subscriptions and API usage separately, check your current plan tier against OpenAI's own billing documentation to confirm whether these credits apply to your account and whether they expire — then see if you can retire a redundant charge.
Who should care
Whoever owns your software budget or your developer tooling spend, specifically teams on the $100+ ChatGPT or Anthropic tiers that also pay for API calls.
Skip this if
You don't build anything against the OpenAI or Anthropic APIs, or you're not on one of the named higher-tier plans — this is purely a billing perk, not a capability change.
