# Configuration

Prism's flexible configuration allows you to easily set up and switch between different AI providers. Let's dive into how you can configure Prism to work with your preferred providers.

## Configuration File

After installation, you'll find the Prism configuration file at `config/prism.php`. If you haven't published it yet, you can do so with:

```bash
php artisan vendor:publish --tag=prism-config
```

Let's break down the key sections of this configuration file:

```php
return [
    'prism_server' => [
        'enabled' => env('PRISM_SERVER_ENABLED', true),
    ],
    'providers' => [
        // Provider configurations here
    ],
];
```

## Provider Configuration

Prism uses a straightforward provider configuration system that lets you set up multiple AI providers in one place. Each provider has its own section in the configuration file where you can specify:

- API credentials
- Base URLs (useful for self-hosted instances or custom endpoints)
- Other Provider-specific settings

Here's a general template for how providers are configured:

```php
'providers' => [
    'provider-name' => [
        'api_key' => env('PROVIDER_API_KEY', ''),
        'url' => env('PROVIDER_URL', 'https://api.provider.com'),
        // Other provider-specific settings
    ],
],
```

## Environment Variables

Prism follows Laravel's environment configuration best practices. All sensitive or environment-specific values should be stored in your `.env` file. Here's how it works:

1. Each provider's configuration pulls values from environment variables
2. Default values are provided as fallbacks
3. Environment variables follow a predictable naming pattern:
   - API keys: `PROVIDER_API_KEY`
   - URLs: `PROVIDER_URL`
   - Other settings: `PROVIDER_SETTING_NAME`

For example:

```shell
# Prism Server Configuration
PRISM_SERVER_ENABLED=true

# Provider Configuration
PROVIDER_API_KEY=your-api-key-here
PROVIDER_URL=https://custom-endpoint.com

```
> [!NOTE]
> Remember to always refer to your chosen provider's documentation pages for the most up-to-date configuration options and requirements specific to that provider.
