The bulk of the work to support this feature was implemented in these PRs:

• feat: add support for login with ChatGPT #1212
• feat: port maybeRedeemCredits() from get-api-key.tsx to login_with_chatgpt.py #1221

That said, I know there are cases where users may or may not have credits, differences between Pro and Plus, etc., and we need to be sure that all edge cases are addressed and that users see appropriate messaging.
