# Billing plans

> Understand our different billing plans and learn how to update your plan

Billing plans determine how your organization is billed, what types of endpoints
you can access, and what rate limit tiers are available to you.

## Compare plans

There are two billing plans:

| Plan       | Billing method                     | Access                         | Rate limit tier |
| ---------- | ---------------------------------- | ------------------------------ | --------------- |
| Starter    | Buy credits                        | Shared endpoints only          | Tiers 1 and 2   |
| Enterprise | Contract and usage-based invoicing | Shared and dedicated endpoints | Tiers 3 and 4   |

For specific rate limits per tier, see
[Rate limits](/administration/rate-limits).

## Manage billing

The **[Billing](https://console.modular.com/billing)** page in the console
includes:

* **Credits**: see your current balance, add additional credits, and view
  plan details.
* **Payment**: add, replace, or remove a payment method.
* **Billing**: monitor the state of the current billing cycle for all models.
* **Invoices**: review and export past invoices.
* **Transactions**: inspect and export individual transactions.

### Credits

On the starter plan, you must have credits before you can make inference
requests. Request costs vary by model and usage.

If your credit balance reaches zero, requests that use your API keys return a
401 response. You cannot have negative credits. Add more credits to reactivate
your API keys.

## Access dedicated endpoints

To access dedicated endpoints, you need an Enterprise plan. [Contact
