OpenAI launched a monthly API-credit benefit for eligible ChatGPT Pro and Business subscriptions that have been active for at least seven days, according to 机器之心 and V2EX. Pro 100, Pro 200, and Pro 500 receive matching monthly credits, while Business workspaces receive up to $500 based on seat tier; credits expire at the end of the billing cycle and do not roll over. Users associate an API Organization through ChatGPT or OpenAI billing settings, though some V2EX users reported missing claim entries, including for Google Play subscriptions.
