# OpenRouter

> Unified API for 200+ AI models

<Card>
  **OpenRouter** provides unified access to 200+ AI models:

  * **Single API** - Access models from multiple providers
  * **Automatic fallbacks** - Switch to similar models if unavailable
  * **Competitive pricing** - Transparent passthrough costs
  * **No vendor lock-in** - Switch models instantly
  * **Model discovery** - Find the best model for your task
</Card>

***

## Pricing Model

### Dynamic Passthrough Pricing

OpenRouter uses **passthrough pricing** where you pay the vendor's cost plus OpenRouter fee, then Splox platform fee.

<Info>
  **Pricing Formula:**

  `Final Price = (Vendor Cost + OpenRouter Fee) + Splox Platform Fee`

  Pricing updates automatically when vendors change rates.
</Info>

### How It Works

1. **Select a model** (e.g., `openai/gpt-4`, `anthropic/claude-3-opus`)
2. **OpenRouter routes** your request to the vendor
3. **You're charged** vendor cost + OpenRouter fee + Splox fee
4. **Pricing updates** automatically in real-time

### Example Pricing

Approximate costs (vendor + OpenRouter + Splox fees):

| Provider  | Model           | Input       | Output      |
| --------- | --------------- | ----------- | ----------- |
| OpenAI    | GPT-4o          | \~\$3.25/M  | \~\$13.00/M |
| Anthropic | Claude Opus 4.1 | \~\$19.50/M | \~\$97.50/M |
| Google    | Gemini 2.5 Pro  | \~\$1.62/M  | \~\$13.00/M |
| Meta      | Llama 3.3 70B   | \~\$0.52/M  | \~\$0.52/M  |

<Warning>
  Prices are **estimates** and may vary. Check [OpenRouter Model Directory](https://openrouter.ai/models) for current vendor costs.
