How to stop Stack Overflow training AI on your data
What the policy itself says, plan by plan. Where Stack Overflow publishes the steps, they're here in its own words, read from an archived copy of the page that gives them. Where it doesn't, this page says so instead of inventing a menu path.
Public Network (AI Features)
The AI Addendum is unusually explicit about third parties and silent about Stack Overflow. It requires that trusted third-party providers "do not use the input content or prompts for training their machine learning models" and repeats the same for outputs — a real commitment, plainly written. Against that, the licence quoted here is perpetual and irrevocable, and the purposes it names are "analytics, product development, and product improvement". Training is neither stated nor excluded, and a company that knew how to write the words "for training their machine learning models" one paragraph earlier did not write them here. That asymmetry is the finding. Note separately that public posts are CC BY-SA licensed and published as a data dump, so the training question for Subscriber Content is answered by that licence rather than by this addendum.
