# Model

AXAR AI supports multiple providers to interact with different language models. We can specify the provider and model identifier using the `@model` annotation when defining our agent.

<summary>Setting up provider API keys</summary>

To use a specific provider, set up the required API key as an environment variable. Each provider has a specific environment variable name. For example, if you're using **Anthropic**, you can set the API key like this:

```bash
export ANTHROPIC_API_KEY="sk-proj-YOUR-API-KEY"
```

In development, you can simplify API key management by using the `dotenv` package along with a `.env` file. Here’s how to set it up:

1. **Install the `dotenv` package**\
   Use npm or yarn to install the `dotenv` package:

   ```bash
   npm install dotenv
   # or
   yarn add dotenv
   ```
2. **Create a `.env` file**\
   In the root directory of your project, create a `.env` file and add your API keys:

   ```bash
   ANTHROPIC_API_KEY=sk-proj-YOUR-API-KEY
   ```
3. **Load the `.env` file in your code**\
   Import and configure `dotenv` at the entry point of your application (e.g., `index.ts`):

   ```typescript
   import * as dotenv from 'dotenv';
   // Load environment variables from .env file
   dotenv.config();
   ```
