AI Assist gives me a 429 error

AI Assist keeps giving me an error whenever i try to use it.

Oops, something went wrong. 429 You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors.

My ChatGPT usage dash shows 0 API usage, so it’s not a quota issue. I have created the api key and added it to Observable. My billing is up to date in ChatGPT, though I’m not a paid Observable user.

Anyone else getting this?
