By default, we do not train on any inputs or outputs from our products for business users, including ChatGPT Team, ChatGPT Enterprise, and the API. We offer API customers a way to opt-in to share data with us, such as by providing feedback in the Playground, which we then use to improve our models. Unless they explicitly opt-in, organizations are opted out of data-sharing by default.
The business bit is confusing, I guess they see the API as a business product, but they do not train on API data.
Where does DeepSeek say that about API usage? Their privacy policy says they store all data on servers in China, and their terms of use says that they can use any user data to improve their services. I can’t see anything where they say that they don’t train on API data.

So on API they don't train by default, for other paid subscription they mention you can opt-out
