Who loses what on October 9

For free users, the cut is the sharpest. Anyone on the Gemini web or mobile apps without an active Google AI subscription will be limited to the 3.5 Flash-Lite model, and access to the faster 3.6 Flash and the more capable 3.1 Pro gets removed entirely.

AI Plus subscribers, the entry-level paid tier, don't escape it either, dropping to just Flash-Lite and Flash with the 3.1 Pro model taken away. Things only hold steady higher up. AI Pro subscribers lose nothing and actually gain the advanced Deep Think feature, a mode built for heavy parallel reasoning that used to be locked to the $99.99 and $199.99 plans, while AI Ultra keeps everything, including Deep Think and early access to models before they roll out widely.

The other squeeze: usage limits

Alongside the model reshuffle, Google is adding limits to media generation, Deep Research and the Pro model, and it laid out how the new metering works.

"Gemini will move to compute-based usage limits that will refresh every 5 hours until you reach your weekly limit. Calculation of your usage will factor in the complexity of your prompt, the features you use, and the length of your chat.

Paid users have higher limits than users without a Google AI subscription. Premium models and features require more usage and may cause you to reach your limit faster," the company said.

In plain terms, everything you do now draws down a budget. A free account gets the standard limit, AI Plus gets double that, AI Pro gets four times, and AI Ultra gets five to twenty times an AI Pro allowance depending on the plan.

The heavier the request and the fancier the model, the quicker you hit the wall.

What it really means

Strip away the version numbers and this is Google turning the free tier into more of a demo than a tool. The genuinely useful Gemini, the Pro model, Deep Think, generous limits, now clearly sits behind a subscription, and even the cheapest paid plan has been thinned out to make the step up look worth it.

It fits a pattern across the industry, where the free and low-cost tiers keep getting quietly trimmed as the real cost of running these models catches up with the companies offering them.

The date to remember is October 9, when the free ride drops to Flash-Lite.
