## Quick start

Use the OpenAI SDK with Clonvo’s base URL and this model id.

```python
import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.clonvo.com/v1",
    api_key=os.environ["CLONVO_API_KEY"],
)

completion = client.chat.completions.create(
    model="deepseek/deepseek-v4-pro",
    messages=[{"role": "user", "content": "Summarise the plot of Hamlet in one sentence."}],
)
print(completion.choices[0].message.content)
```

## Data policy

Requests to this model are sent to DeepSeek, whose API terms govern how they handle your data: [DeepSeek data policy](https://cdn.deepseek.com/policies/en-US/deepseek-privacy-policy.html). Clonvo doesn’t store prompts or responses unless your organization turns on retention.

## Bring your own key

From Pay as you go up, a DeepSeek key added under Provider keys is used for this model before your credits: $25,000 a month free, then 4% of list price. [How bring-your-own-key works](https://clonvo.com/docs/byok.md).
