You switched it all off. Chrome updated. And there is a Gemini button winking at you again. Before you blame the update, read this — the cause is almost never what it looks like, and each real cause has its own permanent fix.
Few tech frustrations repeat as reliably as this one: you spend ten minutes switching off Chrome's AI, an update lands, and AI is back. It feels deliberate. The truth is duller and more useful: your settings almost certainly survived. What changed is one of three things — a new feature arrived with its own fresh default, a flag you relied on expired, or a control moved house during a rollout. This page separates the three, because fixing the wrong cause guarantees a repeat performance.
Chrome settings are stored in your profile and are designed to persist across updates. A feature you switched off at chrome://settings/ai does not normally switch itself back on because Chrome updated. When users report that "everything came back", the post-mortem almost always finds one of the three real causes below — and each has a different fix.
Google ships AI features one at a time, all year. You disabled Help me write in March; in June a new feature — a Gemini button, an AI Mode entry in the address bar, a new tab tool — arrives switched on, because it is a different feature with its own fresh default. Your old toggle is still off. The browser just has a new tenant.
The fix: after any major Chrome update, spend two minutes on the AI innovations page and switch off whatever newly appeared. Make it a habit, like checking the mirrors after someone else drove your car.
If you removed a feature with a chrome://flags switch — the Glic flag for Gemini, for example — you built on rented land. Flags are experiments: Google renames and removes them as features ship, and when a disabled flag disappears, the feature it was holding back returns to its default, which for AI features usually means on.
The fix: move the job to the settings toggles, which are built to persist. Keep flags only for leftovers settings cannot reach, and keep a note of their names so a post-update check takes minutes.
During gradual rollouts, Google also rearranges the furniture: a control that lived under one section appears under AI innovations instead, a toggle gets renamed, or a feature graduates from experiment to standard setting. The setting itself usually survived — but the page you remembered no longer shows it, and the feature's new home shows its current state in a place you never check.
The fix: use the settings search box. Open Settings, type AI or the feature's name in the search field at the top, and Chrome will list every related control wherever it currently lives. Add chrome://on-device-internals to the round — it tells you plainly whether the on-device model is present and active after the update.

On your own Windows PC you can set Chrome's AI policies yourself (see the guide on office policy locks) — policy values are the most update-resistant switches Chrome has.

What updates do is add new features that arrive switched on, retire experimental flags, and occasionally move a control to a different settings section — all of which can look like a reset.
If the On-device AI setting is still on, Chrome will fetch the model again whenever it is missing or a feature needs it — including after profile repairs and some major updates. Turning off On-device AI under Settings, System is the switch that stops the downloads; deleting the model folder alone does not.
Use settings toggles rather than flags, run the two-minute check on chrome://settings/ai after major updates, and — on your own Windows PC — consider setting Chrome's documented AI policies yourself, since policy values are applied above user settings and are the most update-resistant control Chrome offers.
