# OpenRouter Configuration
[OpenRouter](https://openrouter.ai) is a standalone, premium service
that provides access to a wide range of AI models from multiple providers through a single API.
This document details the process of integrating OpenRouter with big-AGI.
### 1. OpenRouter Account Setup and API Key Generation
1. Register for an OpenRouter account at [openrouter.ai](https://openrouter.ai) by clicking on Sign In > Continue with Google.
2. Top up your account (minimum $5) by navigating to [openrouter.ai/account](https://openrouter.ai/account) > Add Credits > Pay with Stripe.
3. Generate an API key at [openrouter.ai/keys](https://openrouter.ai/keys) > API Key > Generate API Key.
- **Remember to copy and securely store your API key** - the key will not be displayed again and will be in the format `sk-or-v1-...`.
- Keep the key confidential as it can be used to expend your credits.
### 2. Integrating OpenRouter with big-AGI
1. Launch big-AGI, and navigate to the AI **Models** settings.
2. Add a Vendor, and select **OpenRouter**.

4. Models from all supported providers will now be accessible and selectable in the application.
In addition to using the UI, configuration can also be done using
[environment variables](environment-variables.md).
### Pricing
OpenRouter independently manages its service and pricing and is not affiliated with big-AGI.
For more detailed information, please visit [this page](https://openrouter.ai/docs#models).
Please note that running large models can be costly and may rapidly consume credits.
Check model pricing on the OpenRouter website before use.
