Google is cutting free Gemini users off from the Flash and Pro models starting October 9, leaving them with only Flash-Lite, the fastest and least capable model in the lineup.
The standalone Gemini app passed one billion monthly users over the summer, according to chief executive Sundar Pichai, and most of them pay nothing, meaning the downgrade will reach the bulk of the product's audience.
Paid tiers shift too: AI Plus, priced $4.99 a month in the US, keeps Flash-Lite and Flash but loses Pro, making AI Pro at $19.99 a month the cheapest plan that still includes Pro.
AI Pro subscribers also gain Deep Think, a mode that runs several lines of reasoning in parallel before answering, previously reserved for plans costing between $99.99 and $199.99 a month.
Google is simultaneously adding low, medium and high effort settings across its models, a dial that trades thoroughness for usage allowance rather than quality alone, since Gemini already meters usage by computing power consumed per request.
The change follows a year of gradual tier reshuffling in which the free tier had offered Flash and Pro access alongside Flash-Lite, before Google moved toward tighter gating and clearer paid distinctions.
Google has not published performance comparisons showing how much weaker Flash-Lite is on common tasks like summarising documents or trip planning, nor clarified where Gemini 4 Argon, its new frontier model launching first for AI Ultra subscribers, will sit in the new structure.
AI Plus subscribers will get an email detailing when Pro disappears from their accounts, and the effort controls begin rolling out across the Gemini app during October.
