Google AI Plus subscribers who want to choose a Pro model in Gemini now face a $15 monthly price difference. Google said in a subscriber email that from Nov. 13, manual Pro-model selection in the Gemini app and in AI Mode in Google Search would be limited to Google AI Pro and higher tiers. 9to5Google published the notice. Google’s current U.S. plan pages list the $4.99 Plus plan with Gemini 4 Hydrogen and the $19.99 Pro plan with Gemini 4 Argon.
The change affects which model you can select. Google’s notice said chats previously started with a Pro model can continue with a different model. Google lists Hydrogen for the Gemini app and Google Search. That rollout is separate from which subscription lets you pick Argon. If you use both the app and Search, the notice applies to manual Pro selection in both places.
What the extra $15 buys
At the advertised U.S. monthly prices, keeping Plus for 12 months costs $59.88. Paying for Pro monthly for a year costs $239.88. The difference is $180 before tax, discounts or any annual-plan offer. The figures use monthly billing so they show the cost if you leave the same plan in place for a year.
Plus includes 400 GB of storage across Gmail, Drive and Photos, along with Gemini 4 Hydrogen and access to Deep Research. Pro’s current subscription page lists 5 TB of shared storage and access to both Argon and Hydrogen. Google’s limits page gives Plus twice the standard Gemini app usage allowance and Pro four times the standard allowance. Those are relative allowances. A long document or a research task can use more of the allowance than a short chat, so the figures do not translate directly to a fixed number of questions.
Google also lists a 128,000-token context window for Plus and one million for Pro. That determines how much material Gemini can work with at one time. A subscriber who regularly asks Gemini to read long reports or keep track of a long conversation is comparing that capacity as well as the choice of model. If you mainly use Plus for its shared storage, the 400 GB allowance remains on Google’s plan page. Before switching to a smaller storage plan, check how much space you use across Gmail, Drive and Photos. You can review available plans and their billing terms under Manage membership in Google One. Compare the recurring price with any introductory offer shown to your account.
