# Rate Limits

> Understanding rate limits and access tiers for NagaAI models.

Rate limits mainly matter for free models. Paid models do not use the same fixed request caps, though all traffic is still protected against abuse.

## How Rate Limits Work

NagaAI has two access categories: free models and paid models.

### Free Models

All **`:free`** models share a combined rate limit:

| Limit Type                    | Value |
| ----------------------------- | ----- |
| **Requests per Minute (RPM)** | 10    |
| **Requests per Day (RPD)**    | 100   |

<Info>
  **Finding Free Models** You can view all available free models on **[our
  models page](https://naga.ac/models?q=free)** — just look for the `:free` tag.
</Info>

These limits apply whether or not your account has a positive balance.

Free models are a good fit for:

* Testing and experimentation
* Getting familiar with the API

### Paid Models

Paid models do not have the same fixed RPM and RPD caps. In practice, your usage is mainly constrained by:

* **Your account balance**: you need enough credits to process requests
* **Abuse protection**: platform security systems still protect against automated abuse and denial-of-service traffic

## Getting Access to Paid Models

To unlock access to paid models, you need to:

1. **Top up your balance** with a minimum of **\$5** through the [Billing Dashboard](https://naga.ac/dashboard/credits)
2. **Maintain a positive balance** — As long as you have credits, you can use paid models

Your account is typically upgraded right after the first top-up, which unlocks paid-model access.
