OpenAI rewrote this help article between Sep 21 and Sep 23, 2026. The three sentences Terms quotes were reworded, not dropped, and the answers still hold: business and API data is not used to improve models by default (the list now also names ChatGPT Edu), app conversations may be used to train unless you opt out, and the opt-out settings are the same. New: a temporary chat you save becomes a regular chat and follows your model-improvement setting. Terms now quotes the new wording.

After this change the quoted clause for trains on app data is no longer on the page. The answer is flagged until a person re-reads it.

After this change the quoted clause for trains on api data, opt-out was no longer on the page word for word. The answers were checked against the page again afterwards; their history is on the vendor page.

To opt out, turn off Improve the model for everyone under Settings > Data controls in ChatGPT, or select Do not train on my content in our Privacy Portal .
Added: Either option is sufficient for ChatGPT conversations and Codex tasks. You don't need to do both. After you opt out, we won't use your new conversations to improve our models. For more information, see: Data controls in ChatGPT .
Added: Even if you have opted out of training, you can still choose to provide feedback to us about your interactions with our products (for instance, by selecting thumbs up or thumbs down on a model response). If you choose to provide feedback, the entire conversation associated with that feedback may be used to train our models.
Added: Conversations with OpenAI Support may be used to improve OpenAI services, including our models, if Improve the model for everyone is enabled in Settings .
Added: Codex has a separate Include environments setting in Codex settings for allowing training on full environments. Changing your settings in ChatGPT or the Privacy Portal does not change that setting.

Removed: Learn more about how OpenAI uses content from our services to improve and train our models.
Removed: One of the most useful and promising features of AI models is that they can improve over time. We continuously improve our models through research breakthroughs as well as exposure to real-world problems and data. When you allow your content to be used to train our models, it helps our models become more accurate and better at solving your specific problems and it also helps improve their general capabilities and safety. ChatGPT, for instance, improves by further training on the conversations people have with it, unless you opt out .
Removed: When you use our services for individuals such as ChatGPT and Codex, we may use your content to train our models.
Removed: To opt out of model training, you can turn off "Improve the model for everyone" in ChatGPT under Settings → Data Controls, or select "Do not train on my content" in our privacy portal . For ChatGPT and Codex tasks, either option is sufficient. You do not need to opt out in both places. After you opt out, we won't train our models on your new conversations. See our Data Controls FAQ for instructions for ChatGPT conversations and Codex tasks.
Added: By default, we don't use inputs or outputs from ChatGPT Business, ChatGPT Enterprise, ChatGPT Edu, or our API to improve our models. The same applies to content in ChatGPT for Academic Researchers workspaces.
Added: API organization owners can enable data sharing. When they do, members can choose to share feedback and the current API Playground chat to help improve OpenAI models.
Added: For information about how we handle business data, see: Enterprise privacy .

Removed: Even if you have opted out of training, you can still choose to provide feedback to us about your interactions with our products (for instance, by selecting thumbs up or thumbs down on a model response).

Removed: Your support conversations may be used to improve OpenAI services, including our models, if training is enabled in Settings.

Removed: Codex has separate controls for allowing training on full environments, which you can manage in the Codex Settings . Note that adjusting your settings in the ChatGPT interface or privacy portal will not affect these full-environment Codex settings.
Removed: By default, we do not train on any inputs or outputs from our products for business users, including ChatGPT Business, 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.
Removed: Please see our Enterprise Privacy page for information on how we handle business data.
Removed: We retain certain data from your interactions with us, but we take steps to reduce the amount of personal information in our training datasets before they are used to improve and train our models. This data helps us better understand user needs and preferences, allowing our model to become more efficient over time.
