Google’s help page on Gemini model access says that starting October 9, 2026, people using Gemini without a plan will be limited to the Flash-Lite model. Flash and Pro move to paid tiers. If you open the model picker for quick questions, drafts, or homework help, that menu is about to get shorter unless you pay. The same page adds low, medium, and high effort levels for every available model, a quieter change that decides how fast your usage allowance disappears.
TL;DR: From October 9, 2026, Gemini users without a plan get Flash-Lite only, according to Google’s help page. AI Plus adds Flash, AI Pro and AI Ultra add Pro, and Deep Think is listed for Pro and Ultra. Every model gets low, medium, and high effort settings, and higher effort uses more of an allowance that refreshes every 5 hours. AI Plus subscribers get an email with their own transition date.
Gemini model access by plan, starting October 9
Google’s page, titled Changes to Gemini model access and limits, lays out four tiers. Users without a plan get Flash-Lite only. AI Plus adds Flash, while AI Pro and AI Ultra include Flash-Lite, Flash, and Pro.
The October 9 date applies to people without a subscription. AI Plus subscribers will instead get an email telling them when their own switch happens, so the date on your calendar may not be the one that applies to you.
| Plan | US price per month | Models listed | Deep Think |
|---|---|---|---|
| No plan | Free | Flash-Lite | Not listed |
| AI Plus | $4.99 | Flash-Lite, Flash | Not listed |
| AI Pro | $19.99 | Flash-Lite, Flash, Pro | Yes |
| AI Ultra | From $99.99 | Flash-Lite, Flash, Pro | Yes |
Model lists come from the help page above, and prices come from Google’s own Gemini subscriptions page.
Think about anyone who currently picks a stronger model for a long email or a tricky spreadsheet formula without paying. If that is you, Flash-Lite is the only model waiting once the change reaches your account. The model list is only half of the update, though, and the other half is easier to miss.
How effort levels and usage limits change your allowance
For each available model, the help page says you can choose an effort level of low, medium, or high. Higher effort improves how well a task gets completed, but it also consumes more of your usage quota.
Usage is compute based. Limits refresh every 5 hours until a weekly maximum is reached, and prompt complexity, feature use, and chat length all factor in. Google lists AI Plus at 2x the standard limit and AI Pro at 4x, with AI Ultra higher still.
Premium features draw down more usage, and the page names media generation, Deep Research, the Pro model, and extended thinking. Combining several of those in one request is likely to burn through an allowance faster than a plain chat would. The effort dial is a sensible idea, but it quietly turns a model choice into a budgeting decision.
That budget has a ceiling, and the plans separate most clearly at the top of it.
Deep Think and the plans that include it
Google describes Deep Think as an option for maximum parallel reasoning, and says it is available if you have an AI Pro or AI Ultra subscription. AI Plus and the no plan tier are not mentioned for it.
The dollar gap is worth seeing plainly. AI Plus costs $4.99 a month and adds Flash, while AI Pro costs $19.99, a $15 step up that is the first to bring in both Pro and Deep Think.
The help page does not mention Gemini 4 Argon, and our report on Gemini 4 Argon availability found it limited to Ultra subscribers and paid API customers for now.
What to check before the Gemini switch lands
Google’s page asks people to update to the latest Gemini mobile app version, which is a cheap thing to do before the menu changes on your phone.
If you pay for AI Plus, watch your inbox for the transition email instead of assuming October 9 applies. And if you lean on custom Gems, our report on Gems retiring for Skills covers a separate October 13, 2026 deadline.
Who actually needs to pay for Gemini now
Google’s page does not compare how Flash-Lite, Flash, and Pro perform, so there is no official answer to whether Flash-Lite will feel like a downgrade for your habits. The practical test is to run your usual prompts on Flash-Lite before October 9, if your model picker lets you.
For short questions, rewrites, and quick lookups, that may be enough. The paid tiers start to matter when you want Pro for heavier work or Deep Think, and when you notice your allowance running out before the 5 hour refresh.
