Google is reworking which Gemini models are available on each of its plans. Starting October 9, users on the free tier and the AI Plus plan will lose access to some models, while AI Pro subscribers are set to gain a feature that was previously exclusive to the top tier. The company also appears to be working on new reasoning controls for the Gemini app.
What Changes for Free and AI Plus Users
According to an updated Google support document, people without a Google AI subscription will be left with only Flash-Lite from October 9. Flash and Pro will no longer be part of the free plan.
AI Plus, which costs $4.99 (roughly Rs 500) a month, will keep Flash-Lite and Flash but drop the Pro model. Google said affected AI Plus users will get an email telling them when their accounts will switch over.
AI Pro and AI Ultra subscribers keep all three models: Flash-Lite, Flash and Pro.

Why Usage Limits Matter More Now
The changes come after Google started measuring Gemini usage earlier this year based on how much computing power each request requires. This means that heavier requests, such as tricky questions, long back-and-forth chats or the more advanced models, draw down a user's quota more quickly.
Deep Think Arrives on AI Pro
Until now, Deep Think was available only to AI Ultra subscribers. It is now coming to the AI Pro plan, priced at $19.99 (roughly Rs 1,900) a month. AI Ultra users, on either the $99.99 (roughly Rs 9,600) or $199.99 (roughly Rs 19,300) monthly plan, will still have it. Deep Think tackles complex tasks using parallel reasoning and works only with the Pro model.

New Thinking Levels May Be On The Way
Gemini could let users pick from Low, Medium and High thinking settings to decide how much effort the chatbot puts into a response. Choosing a higher level could use up more of a user's allowance. Right now, the Gemini app has an Extended Thinking option for harder problems. Google AI Studio and Antigravity already give users comparable controls.
Gemini 4 Argon Testing Continues
Google is also preparing to roll out Gemini 4 Argon more widely. The model is currently being tested by trusted cybersecurity professionals under the company's Fairwind programme. AI Ultra subscribers and paying API customers will get access at a later stage. It's still unclear whether Argon will sit within the Pro tier or in a separate, higher tier.
