API credits benefit for eligible ChatGPT subscriptions

Read the original on Simon Willison →

Anthropic and OpenAI have introduced matching API credit benefits for their premium ChatGPT subscription plans. Subscribers paying $100, $200, or $500 per month receive an equivalent amount of expiring credits that can be applied to their respective APIs. The author, who holds subscriptions with both services, notes this allows for immediate use in public-facing demos without additional cost.
