The headline feature is auto-deleting chat histories. Users will get a Siri setting that toggles between saving chatlogs for 30 days, one year, or forever.

Competing chatbots like ChatGPT offer a temporary chat mode, but Apple’s stance is that privacy protections should be ingrained in the system itself rather than offered as a manual setting users must enable.
