Upgrade, Change, or Cancel a Google AI Plan in Gemini

A Google AI plan is what unlocks higher Gemini limits and, after October 9, 2026, the models a personal account can still pick. You manage that plan from Gemini Apps, not from a separate store listing buried in settings.

Google documents the flow on Manage your Google AI plan from Gemini Apps. The steps below follow that page. They apply to a personal Google Account. A work or school account uses a different path.

If you are deciding whether you need a plan at all, read the Gemini model access changes on October 9 first. Free accounts keep Flash-Lite. AI Plus keeps Flash. Pro and Deep Think stay on AI Pro and AI Ultra.

Who can subscribe

Google requires an age check before a personal account can pair Gemini Apps with a Google AI plan. In most countries you must be 13, or the applicable age in your country, or older. In the European Economic Area, Switzerland, and the United Kingdom you must be 18 or older.

Some features stay unavailable under 18, or under 13 where that is the local minimum. Plan names also vary by country. Google says some Google AI plans are only sold in certain countries, and the checkout screen is the source of the price and the feature list.

Update the Gemini mobile app before you rely on the subscription menu. Google says the latest app version is required for the best experience with the related model changes.

Subscribe when you have no plan

Subscriptions run through Google One. On the web:

1. Go to gemini.google.com and sign in with the personal account you use for Gemini.
2. At the bottom, click Settings & help, then View Subscriptions.
3. Select the Google AI plan you want.
4. Follow the on-screen instructions and choose or add a payment method.

Do this on a computer if the phone menu is missing View Subscriptions. The help page is written for the computer flow. The same Google Account then carries the plan into the Gemini app after you sign in there.

Google’s payment step is required at signup. You can review cards later in Google payments. Do not start a second subscription on a different Google Account if the chats you care about live on the first one.

Upgrade a plan you already have

If you already pay for AI Plus and need Pro after the model split, stay in Gemini rather than hunting for a new product.

1. Go to gemini.google.com.
2. At the bottom, click Settings & help.
3. Click the available upgrade option.
4. Follow the on-screen instructions.

Google also links an upgrade path from Google One. Confirm the account email in the corner matches the account that owns your chats. An upgrade on a spare login will not move Pro access onto the account you use daily.

After the plan updates, start a new chat and open the model menu near the composer. You must be signed in to switch models. If a paid account hits its limit, Google says you can continue that chat with Flash-Lite.

Change membership in Google One

Switching between plans, including a downgrade, is a Google One action.

1. On your computer, open Google One.
2. Click Manage membership, then Change membership plan.
3. Choose the new plan. Upgrades appear under Upgrade options. Downgrades appear under Downgrade options. If no downgrade is listed, you are already on the lowest plan.
4. Click See all benefits to review what the membership includes.
5. Click Yes, continue after you check the price and details.
6. Select the payment method and click Subscribe.

Read the benefit list before you confirm. A Google AI plan is bundled with storage and other Google One perks. Dropping a tier can change more than the Gemini model menu. The checkout page is where Google shows the exact bundle for your country.

AI Plus subscribers should also watch the inbox tied to that account. Google’s model-access note says Plus users receive an email that explains when the Pro cutoff reaches them. October 9 is the start date for accounts with no plan, not an automatic Plus date.

Cancel the plan

Cancellation also starts in Gemini and finishes in Google One.

1. Go to gemini.google.com.
2. At the bottom, click Settings & help, then Manage subscription. That opens Google One settings.
3. Click Cancel membership, then Cancel.

Cancel only after you have exported anything you still need from Pro-only chats and checked storage use in Google One. The help page routes cancellation through membership settings. It does not describe an instant refund or an instant wipe of chat history. Assume access continues until the end of the paid period unless the confirmation screen says otherwise.

If you subscribed on a phone through a store billing account, the web Cancel membership button can still be the right control, because Google documents the plan as a Google One membership. If the button is missing, open Google One settings while signed into the same account and look for the membership there.

Check the model after the plan changes

A successful payment does not always refresh an old chat.

1. Sign out of extra Google Accounts in the browser, or use a private window, so you are not editing the wrong profile.
2. Open a new Gemini chat.
3. Select the model in the text box at the bottom. Labels can read Flash-Lite, Flash, or Pro, depending on the plan and the app version.
4. If you have AI Pro or AI Ultra, look for Deep Think. Google describes it as maximum parallel reasoning on those two plans.
5. Set effort to low, medium, or high for the model you picked. Higher effort can return a more complete answer and uses more of your limit.

Usage is compute-based. Google says the window refreshes every five hours until you hit the weekly limit. Prompt length, feature choice, and chat length all count. Media generation, Deep Research, the Pro model, extended thinking, and Deep Think spend the budget faster.

Published multiples on the model-access help page: no plan uses standard limits, AI Plus is 2x, AI Pro is 4x, and AI Ultra is 5x or 20x higher than AI Pro depending on the subscription.

Tips before you pay or cancel

Match the plan to the model, not to the brand name. If your work is short rewrites, Flash-Lite on the free tier may be enough. If you open long documents every day, Plus without Pro will not cover that after Google’s email date.

Keep one payment method current. A failed renewal drops you back toward the free model list even if chats still open.

Do not create a skill or a long project on an account you plan to cancel this week. Skills and chat history stay tied to the Google Account, but the model behind them follows the plan.

Family or shared computers should sign out after checkout. The next person can otherwise burn the five-hour window on your paid account.

Bottom line

Subscribe from Settings & help, then View Subscriptions, on gemini.google.com. Upgrade from the same menu. Change or downgrade under Manage membership in Google One. Cancel from Settings & help, then Manage subscription, and confirm Cancel membership.

Do that on the personal account that owns your chats, then open a new chat and confirm the model list matches the plan you just bought or dropped.
