## 🚀 Why UToken?

### One API, Multiple Models

No need to manage separate accounts and API keys for each AI service:

* **One account**: Manage all AI services
* **One API key**: Access all models
* **One standard**: OpenAI API compatible

### 🔧 Easy to Use

Switching models is as simple as changing a parameter:

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

client = OpenAI(
    api_key="sk-xxxxxxxxxx",
    base_url="https://utoken.yoostudio.ai/v1"
)

# Use GPT-5.5
response = client.chat.completions.create(
    model="gpt-5.5",
    messages=[{"role": "user", "content": "Hello!"}]
)

# Switch to Claude - just change the model name
response = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[{"role": "user", "content": "Hello!"}]
)
```

### 🛡️ Stable & Reliable

* **High Availability**: Multi-node deployment, smart routing
