Custom GPT and Knowledge Ownership

If I create a private custom version of ChatGPT which includes my company’s own data that I have uploaded as Knowledge, is this model proprietary to my company since it is based on our proprietary data and shaped by us? Does OpenAI have access to this data?

Similarly, if I integrate ChatGPT into my own app, is this same model that is shaped by my team and the app’s users proprietary to my company?


Please do not ask me follow-up questions as I do not work for OpenAI, I can only point you to the public documents.
