# AI Model Selection

## 🧠 **Choose Your AI Engine**

### **Provider Connection Requirements**

> **⚠️ Important**: To use models from any provider (except AgenticFlow), you must first add a connection for that provider in your project's **Connection Settings**.
>
> * **AgenticFlow Provider**: Uses your AgenticFlow credits directly - no connection setup required
> * **All Other Providers**: Require a valid connection configured in Connection Settings
> * **Automatic Selection**: The server automatically uses the first available connection for the selected model's provider

**How to add a provider connection:**

1. Navigate to your project's **Connection Settings**
2. Add a new connection for your desired provider (OpenAI, Anthropic, Google, etc.)
3. Configure the required API keys and credentials
4. Once connected, you can select models from that provider in your agent configuration
