# Model Pricing

> Per-model token pricing for all supported models.

## How Pricing Works

Credits are deducted based on token usage. Each model has different input and output token rates. Prices are listed per **1 million tokens**.

* **Subscription credits** are consumed at the base rates shown below
* **Lifetime credits** receive your plan's discount (20% / 30% / 50% off)

## Google Models

| Model | Input / 1M tokens | Output / 1M tokens |
| - | - | - |
| `gemini-2.5-pro` | \$1.25 | \$10.00 |
| `gemini-2.5-flash` | \$0.15 | \$0.60 |
| `gemini-2.0-flash` | \$0.10 | \$0.40 |

## Lifetime Credit Discount Example

With the **Pro** plan (30% discount on lifetime credits):

| Model | Base Output Rate | Your Effective Rate |
| - | - | - |
| `claude-sonnet-4-5` | \$15.00 / 1M tokens | \$10.50 / 1M tokens |
| `gpt-4o` | \$10.00 / 1M tokens | \$7.00 / 1M tokens |
| `gemini-2.5-flash` | \$0.60 / 1M tokens | \$0.42 / 1M tokens |

## Cost Estimation

To estimate the cost of a request:

```
Cost = (input_tokens × input_rate / 1,000,000) + (output_tokens × output_rate / 1,000,000)
```

**Example:** A request to `claude-sonnet-4-5` with 1,000 input tokens and 500 output tokens:

```
Cost = (1,000 × $3.00 / 1,000,000) + (500 × $15.00 / 1,000,000)
     = $0.003 + $0.0075
     = $0.0105
```
