## Data policy

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

## Bring your own key

From Pay as you go up, a OpenAI 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).
