# OpenAI Format Converter

> Use Gemini and Anthropic models with OpenAI SDK

## Overview

The OpenAI Format Converter allows you to call **Gemini** and **Anthropic** models using the OpenAI SDK and API format. This is useful when you have existing code using the OpenAI SDK but want to access other providers' models.

## Configuration

### SDK Configuration

Set your base URL to:

```
https://api.pipellm.ai/openai
```

<Note>
  The SDK automatically appends `/chat/completions`, so you only need to set the
  base URL to `/openai/v1`.
</Note>

### cURL / Direct API

For direct API calls, use the full endpoint:

```
https://api.pipellm.ai/openai/v1/chat/completions
```
