Does ChatGPT train on your data?

OpenAI · AI assistants

By default it can. On the consumer tier ChatGPT uses your inputs to improve models unless you opt out. Its business tier typically does not.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

Default data training: Opt-out required; On free/Plus consumer ChatGPT, conversations are used to improve models by default unless you turn off 'Improve the model for everyone' in data controls.
Business-tier training: No by default; OpenAI does not train on inputs or outputs from ChatGPT Team, ChatGPT Enterprise, or the API platform by default.
Training control: Confirmed; OpenAI documents a training control. Confirm whether it is enabled centrally or must be set by each user.

Practical risk: Consumer/free ChatGPT uses your chats for training unless you proactively disable it, so staff pasting work data into personal accounts can leak it into model improvement.

How to make a decision

Check the precise account tier, written contract and intended data before approving ChatGPT. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
