For consumer AI products and non-enterprise business accounts, if you look closely at the ToS it says that you retain the rights to your inputs and the outputs you receive, collectively called “content”. You can opt-out of training in your content. However that doesn’t cover the results of tool calls - which are fair game for training. As are any “safety events”, which as far as I can tell is a euphemism for “something the model has never seen before” - including enterprise accounts when it comes to “AI safety.”
