OpenAI clearly states that they train on your data https://help.openai.com/en/articles/5722486-how-your-data-is...

[lemming]

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.

So for posterity, in this subthread we found that OpenAI indeed trains on user data and it isn't something that only DeepSeek does.

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