Gemini Model Limits Change on October 9: What Free and AI Plus Users Lose

Table showing which Gemini models free, AI Plus, AI Pro and AI Ultra users can access from October 2026

Google is putting new Gemini model limits on the Gemini app, and the free tier takes the biggest hit. From October 9, people without a paid Google AI plan can only use the smallest model. Google AI Plus subscribers lose Pro. Google AI Pro subscribers lose nothing and gain Deep Think.

Key takeaways

  • Free users are limited to Gemini 3.5 Flash-Lite starting October 9. Gemini 3.6 Flash and 3.1 Pro are gone for them.
  • Google AI Plus keeps Flash-Lite and Flash but loses Pro.
  • Google AI Pro and AI Ultra keep every model. AI Pro adds Deep Think.
  • Low, medium and high effort levels are expected in the app this month.
  • Gemini 4 Argon launches first for AI Ultra, and its place in the lineup is still unclear.

What are the new Gemini model limits?

Free Gemini app users will be limited to Gemini 3.5 Flash-Lite from October 9. Google AI Plus subscribers lose Gemini 3.1 Pro and keep Flash-Lite and Flash, with timing set by email. AI Pro and AI Ultra keep all models, and AI Pro adds Deep Think.

Here’s the full breakdown, based on Google’s updated support document as reported by 9to5Google:

Google AI planFlash-LiteFlashPro
No plan (free)YesNoNo
AI PlusYesYesNo
AI ProYesYesYes
AI UltraYesYesYes

The models in question are Gemini 3.5 Flash-Lite, Gemini 3.6 Flash and Gemini 3.1 Pro. Free users could reach the last two until now.

When do the changes start?

Free users lose access to Flash and Pro on October 9. For AI Plus, Google says subscribers will get an email explaining when the change takes effect, so there’s no confirmed date yet. If you pay for Plus, watch your inbox before assuming anything.

Does Google AI Pro lose anything?

No. AI Pro keeps Flash-Lite, Flash and Pro. It also picks up the Deep Think option, which gives Gemini maximum parallel reasoning on hard problems. Until now Deep Think sat only on the two top-priced plans, at $99.99 and $199.99 a month. AI Pro costs $19.99 a month, according to 9to5Google. Your regional price may differ.

That’s a real upgrade, and it makes the Pro tier look better value than it did a week ago.

What are the new Gemini effort levels?

The Gemini app is also adding “low,” “medium” and “high” effort settings for each available model. Higher effort gives the model more room to finish tasks and write fuller answers. It also burns through your usage limit faster.

Today you only get a single “Extended thinking” toggle for complex problems. The new three-step setting matches what Google AI Studio and Antigravity already offer. So the effort level becomes a second dial next to the model you pick. A free user stuck on Flash-Lite can still turn effort up, but they’ll hit their cap sooner.

Why is Google doing this?

Google doesn’t say. My read is that it’s compute rationing. Google moved the app to compute-based usage limits in May. Gating which models each plan can reach is the next step on the same road. The bigger models cost more to run, so they move up the paywall.

That’s an inference, not something Google has confirmed. The pattern fits, though, and it explains why Pro-tier perks keep growing while the free tier shrinks.

Where does Gemini 4 Argon fit?

Nobody knows yet. Google announced Gemini 4 Argon on September 30 and said it arrives first for AI Ultra subscribers. It hasn’t said whether Argon counts as a Pro model or a new tier above Pro. That matters for AI Pro subscribers. If Argon is a separate tier, the Pro plan’s top model gets older fast. One of the top comments under the original report makes exactly that complaint about Gemini 3.1 Pro looking dated.

What should you do now?

On the free plan: Expect shorter, simpler answers from Flash-Lite. Quick lookups and light drafting will be fine. Long reasoning, coding and multi-step work will feel weaker. Google AI Studio and the Gemini API follow separate rules, so check those pages before assuming they changed too.

On AI Plus: Decide whether Flash is enough for you. If you used Pro regularly, the jump to AI Pro is about $15 a month at the prices 9to5Google reports, and it brings Pro back plus Deep Think.

On AI Pro or AI Ultra: Nothing breaks. Try the new effort levels when they land and see which tasks actually need the high setting.

Gemini model limits: FAQ

Can free users still use Gemini Pro after October 9?

No. Free Gemini app users without a Google AI subscription are limited to Gemini 3.5 Flash-Lite from October 9. They lose both Gemini 3.6 Flash and Gemini 3.1 Pro. Paid plans are the only way to get those models back in the app.

Does Google AI Plus include Gemini Pro?

Not anymore. Google AI Plus subscribers will be limited to Flash-Lite and Flash. Google will email Plus subscribers with the exact date the change takes effect. Google AI Pro is the cheapest plan that keeps Pro access.

What is Gemini Deep Think?

Deep Think is a Gemini option built for maximum parallel reasoning on hard problems. It previously appeared only on the two highest-priced plans. Google is adding it to AI Pro, so $19.99-a-month subscribers get it too.

What is the cheapest Gemini plan with Pro access?

Google AI Pro, at $19.99 a month according to 9to5Google. AI Plus (4.99) no longer includes Pro. AI Ultra includes it too but costs far more. Regional pricing varies, so check Google’s subscription page for your country.
