- The News: Google released Gemini 3 DeepThink, a “reasoning-heavy” model.
- The Breakthrough: Scored 84.6% on the ARC-AGI-2 benchmark (a massive jump).
- Key Capabilities: Gold medals in Math/Physics Olympiads, 3455 Codeforces Elo.
- Availability: AI Ultra subscribers & API early access.
Gemini 3 DeepThink is officially here, and it isn’t just another chatbot update. In a move that clearly targets OpenAI’s reasoning dominance, Google has dropped a model that fundamentally changes how AI approaches complex problems.
The headline number? 84.6% on ARC-AGI-2. If you follow AI benchmarks, you know that score is essentially “engineering-grade” territory, shattering previous records held by frontier models.
What is Gemini 3 DeepThink?
Think of Gemini 3 DeepThink less as a conversationalist and more as a research assistant that actually thinks before it speaks. Unlike standard LLMs that predict the next token based on probability, DeepThink allocates significant compute to structured reasoning chains.
It evaluates multiple solution paths, self-corrects intermediate steps, and maintains logical consistency across long workflows. This makes it ideal for:
- Advanced mathematical proofs
- Algorithmic code debugging
- Scientific data analysis
- Complex engineering simulations
The Benchmark Breakdown
Google didn’t just release a model; they released a statement. The performance metrics for DeepThink are startlingly high across the board.
ARC-AGI-2: The New Standard
The ARC-AGI benchmark detects an AI’s ability to learn new rules from minimal examples—a proxy for general intelligence. Most models struggle here. DeepThink’s 84.6% represents a leap in abstraction capability.

Why This Matters for Developers
For weeks, the industry has been focused on “interface innovation” (like the IDEs we reviewed recently). Gemini 3 DeepThink shifts the focus back to reasoning infrastructure.
“The labs that achieve stable long-horizon reasoning first will likely shape the next generation of enterprise and developer ecosystems.”
— Demis Hassabis, Google DeepMind CEO
If you’re building autonomous agents or complex R&D pipelines, a model that can sustain a thought process for minutes without hallucinating is the holy grail. DeepThink seems to be Google’s first commercial answer to that need.
How to Access It
Google is rolling this out in tiers:
- Gemini App: Available now for Google AI Ultra subscribers.
- API: Early access for researchers and enterprise partners (check Google AI Studio).
- Free Tier: Not currently available (requires high compute).
Our Verdict
Google is clearly done playing catch-up. With DeepThink, they aren’t just matching the competition—they’re trying to redefine the ceiling of AI intelligence.
