# Tier

This page outlines the different tiers available in the system, their requirements, and the corresponding benefits. All users have access to our serverless endpoints. The tiers dictate your request and token rates, as well as whether you have access to GPU instances.

### **Tier Levels and Benefits**

| Tier            | Requirement     | GPU | CPU | RPM   | TPM     | RPD       |

| Engineer Tier 1 | Sign Up         | ✖   | ✖   | 60    | 60,000  | 200       |
| Engineer Tier 2 | Add Credit Card | ✖   | ✔   | 300   | 150,000 | 1,000     |
| Engineer Tier 3 | Deposit $10     | ✔   | ✔   | 600   | 200,000 | 2,000     |
| Expert Tier 1   | Spend $30       | ✔   | ✔   | 1,500 | 500,000 | Unlimited |
