# Introduction

> Access 40+ AI models with a single API key.

**One API key to access all major AI models.**

Anyone saves you the hassle of registering on multiple AI platforms and managing separate API keys. Just get one API key from Anyone, and you can call GPT-5.4, Claude, Gemini, DeepSeek, and 40+ other models — using the OpenAI SDK you already know, with just a base URL change.

```python theme={null}
from openai import OpenAI

client = OpenAI(
    base_url="https://api.anyone.ai/v1",  # just change this line
    api_key="your Anyone API key",
)

# Use the same client to call any model
response = client.chat.completions.create(
    model="claude-sonnet-4-6",  # or gpt-5.4 / gemini-3.1-pro-preview / DeepSeek-V3.2
    messages=[{"role": "user", "content": "Hello!"}],
)
```
