Does ChatGPT (Free / Plus / Pro) train on your data?

Personal plan OpenAI · Assistant · Last verified

Trains by default

Trains on business data unless you opt out.

Short answer: Yes, opt-out

Free, Plus and Pro: OpenAI may train on your chats unless you turn off "Improve the model for everyone". Opt-out covers new chats only. Thumbs up/down feedback can still send the whole conversation to training even after opting out.

Why this matters: Data used for training can't be pulled back out of a trained model, so opting out only protects what comes after. Why training matters →
