Gemini 3 Deep Think Lands on Google’s Costliest Plan: What It Really Means

Google has pushed its most powerful reasoning model, Gemini 3 Deep Think, to a very exclusive group. The AI Ultra plan now gets access to the model that Google calls its next leap in complex problem-solving. The rollout arrives just weeks after the global release of Gemini 3 Pro, signalling Google’s aggressive push toward advanced reasoning features.

Deep Think Arrives With Record Benchmark Scores

Google first teased Gemini 3 Deep Think last month. Since then, curiosity has surged because of two headline-grabbing benchmark results. The model reportedly scored 41 percent on Humanity’s Last Exam, a test designed to challenge even elite AI systems. The score sets a new bar and pushes the debate around reasoning models forward.

Moreover, Deep Think also posted 45.1 percent on the ARC-AGI-2 benchmark. This test requires models to solve visual puzzles and run code. Google called the achievement “unprecedented” and highlighted its role in evaluating AGI progress. These results suggest a jump in how AI handles logic, structure, and multi-step reasoning.

Parallel Reasoning Powers the New Model

The tech giant also revealed the technique driving the major boost. Google claims Deep Think uses parallel reasoning, which replaces the traditional single chain of thought. The model tries multiple solution paths at once and then refines them through repeated evaluations. This method, Google says, creates stronger and more reliable answers for complex queries.

The shift signals where next-generation models are heading. Instead of linear reasoning, future AI systems may use broader, branching structures to solve intricate tasks faster.

Only Google AI Ultra Users Can Access It

Despite the buzz, most users cannot try the model yet. In India, the Google AI Ultra subscription costs Rs. 24,500 a month, making it one of the costliest AI plans available. Ultra users can open the Gemini website or app, choose Deep Think in the prompt bar, and then pick Gemini 3 Pro to activate the model.

Google’s decision to limit the rollout adds a premium layer to its AI strategy. It also suggests that performance-heavy models may stay locked behind expensive tiers, at least in the near future.

What Comes Next for Gemini 3

With this release, Google continues shaping the narrative around advanced reasoning models. Deep Think sets new benchmarks, introduces a fresh approach, and targets users dealing with higher-order problem-solving. The broader rollout may take time, but today’s release gives a rare glimpse into Google’s most ambitious AI yet.
