OpenAI: Managing your work in the API platform with Projects (via) New OpenAI API feature: you can now create API keys for "projects" that can have a monthly spending cap. The UI for that limit says:

If the project's usage exceeds this amount in a given calendar month (UTC), subsequent API requests will be rejected

You can also set custom token-per-minute and request-per-minute rate limits for individual models.

I've been wanting this for ages: this means it's finally safe to ship a weird public demo on top of their various APIs without risk of accidental bankruptcy if the demo goes viral!
