# How much does Fireworks cost?

Fireworks AI uses a **usage-based pre-paid** model for new self-serve accounts. You purchase credits, then usage is deducted based on:

* **Per token** for serverless inference
* **Per GPU usage time** for on-demand deployments
* **Per token of training data** for fine-tuning

Billing model by account type:

* Accounts created before **June 1** keep their existing postpaid terms (grandfathered).
* Enterprise accounts can be configured for postpaid billing on request.

For customers needing **enterprise-grade security and reliability**, please reach out to us at [inquiries@fireworks.ai](mailto:inquiries@fireworks.ai) to discuss options.
