Google to Iran: Thankyou for using our Gemini for phishing service
"Google says" though "it's spotted Chinese, Russian, Iranian, and North Korean government agents using its Gemini AI for nefarious purposes" it will continue "tracking the use of Gemini by these nations", targeting ads that are relative to an agent's preferences.
From the report it seems to me that Google log and stores all of Gemini AI's prompts not just ones that are caught by its guardrails, probably for every user.. The report links actions by a group to prompts answered by Gemini.
