By default, we do not use your business data for training our models.
- ChatGPT Team or ChatGPT Enterprise
We do not train our models on inputs and outputs through our API.
- OpenAI API Platform
Правда про fine-tuning models все таки есть нюанс.
Q: "Who can view stored API inputs, outputs, and fine-tuning data?"
A: Our access to API business data stored on our systems is limited to (1) authorized employees that require access for engineering support, investigating potential platform abuse, and legal compliance and (2) specialized third-party contractors who are bound by confidentiality and security obligations, solely to review for abuse and misuse.
