Billing

To install an extension, your project must be on the Blaze (pay as you go) plan

You will be charged a small amount (typically around $0.01/month) for the Firebase resources required by this extension (even if it is not used).
This extension uses other Firebase and Google Cloud Platform services, which have associated charges if you exceed the service’s no-cost tier:
- Cloud Firestore (reads/writes for prompt templates and responses)
- Cloud Functions (executions for processing documents)
- ModelPilot API (pay-as-you-go AI inference, typically 40-70% cheaper than direct providers)

You can monitor costs in:

Firebase Console for Firestore and Functions
ModelPilot Dashboard for AI API usage
Each processed document’s metadata includes the exact cost of that request, you’re only charged for the underlying resources that you use. A paid-tier billing plan is only required if the extension uses a service that requires a paid-tier plan, for example calling to a Google Cloud Platform API or making outbound network requests to non-Google services. All Firebase services offer a free tier of usage. Learn more about Firebase billing.
