A: Yes, you can always top-up your AI credits.
Here, as always, fully transparent how AI credits are being calculated: https://docs.nocode-x.com/licenses-&-billing/Understanding%20AI%20Credits%20and%20Billing
It is also important to know that our users like the single invoice for all these capabilities, that they do not need to have each time a separate subscription for every model… But again if you want to use LLM integrations in your applications, you are free to use the API and implement your own keys.
