JSON Example
```json
{
    "model": "deepseek-ai/DeepSeek-V3.1-Terminus",
    ...
    "thinking": {
        "type": "enabled"s
    }
}
```

Model support

- deepseek-ai/DeepSeek-V3.1-Terminus

### API Example

```python
import json
import requests

# Configure API key
api_key = "******"  # Replace with your API key
url = "https://api-us-ca.umodelverse.ai/v1/chat/completions"

headers = {"Authorization": f"Bearer {api_key}", "Content-Type": "application/json"}
data = {
    "model": "deepseek-ai/DeepSeek-V3.1-Terminus",  # Specify model
    "messages": [

            ],
        }
    ],
    "thinking": {"type": "enabled"},  # Enable thinking feature, optional: enabled / disabled / auto
}

try:
    response = requests.post(url, headers=headers, json=data)
    response.raise_for_status() 

    print("Request successful!")
    print(json.dumps(response.json(), indent=2, ensure_ascii=False))

except requests.exceptions.RequestException as e:
    print(f"Request failed: {e}")
