Gemini 3 Deep Think — the latest advancement in the Gemini series from Google — has officially been rolled out, but only for subscribers of the company’s priciest plan.
What is Gemini 3 Deep Think?
Gemini 3 Deep Think is more than a typical large language model: it’s an AI system designed to tackle deeply analytical tasks — math, logic, science, coding, and complex reasoning. The distinguishing feature is parallel reasoning: instead of following a single chain of thought, the model simultaneously explores multiple hypotheses before converging on the answer it deems most coherent.
This isn’t just marketing fluff. Google claims the model performs well on rigorous benchmarks: it scored 41% on “Humanity’s Last Exam” (without tools) and 45.1% on the ARC-AGI-2 benchmark (with code execution).
Who Gets Access — and How Much It Costs
Gemini 3 Deep Think is exclusively available to those subscribed to Google AI Ultra — the highest tier offered by Google’s AI subscription lineup.
In India, that subscription costs roughly ₹24,500 per month. Users who have the plan can simply open the Gemini app (or the web interface), choose “Deep Think” in the prompt bar and select “Gemini 3 Pro” in the model dropdown — and they’re good to go.
What This Means for AI: A Shift Toward “Thinking” AI
With Deep Think, Google seems to be doubling down on a vision of AI not just as a “chat or helper,” but as a genuine reasoning companion. Rather than simply parroting back learned patterns, the model is built to reason, plan, and solve — all within a single system.
For researchers, developers, professionals working on mathematics, science, coding, or even complex strategic thinking — this could be a game changer. Google suggests that Deep Think can help with algorithm design, step-wise improvements, scientific reasoning, and even building tools or “agents” that require deeper thought processes.
But Access Is Limited — For Now
Because of its high computational demands and premium features, Deep Think remains gated behind the Ultra plan — after all, it’s billed as Google’s “most advanced reasoning mode.”
That means for everyday users — casual chat, simple content generation, or basic queries — the standard or free versions of Gemini remain the only available options. The full power of Gemini 3 Deep Think is reserved for those willing (and able) to pay for the steep price.
Why Google Is Doing This
- Resource-intensive computation: The parallel reasoning architecture demands high compute power, making cost a natural gating factor.
- Targeting serious users: By limiting access, Google ensures that Deep Think is used by power users — researchers, developers, professionals — rather than casual users.
- Competitive positioning: With this step, Google is staking a claim in the “thinking AI” domain, potentially leapfrogging rivals in delivering AI that can reason, not just respond.
As of now, Gemini 3 Deep Think stands as one of the most ambitious attempts to build an AI that doesn’t just generate — it reasons, plans, and solves. But standing at the pinnacle of AI innovation comes at a steep price and with restricted access.
