Have you ever stared at a complex problem and wished you could see the actual thought process behind the answer? 

Here's a Cool Tip:  Think with Gemini 3 Pro.

Google has just rolled out "Thinking with 3 Pro," a new mode in the Gemini app and Google Search that does exactly that, pausing to reason, plan, and even self-correct before it speaks.

What Is "Thinking with 3 Pro"?

"Thinking with 3 Pro" is a specialized toggle available within the Gemini interface that activates Google's Gemini 3 Pro model, released in late 2025. 

Unlike the standard "Fast" mode (powered by Gemini 3 Flash), this mode dedicates significantly more compute power to "ponder" your query. 

It breaks down multi-step problems, writes and tests code internally, and generates dynamic visual layouts, like interactive charts or custom simulations—right in the chat window.

What You’ll Gain

• Transparent Logic: See the "Thought Signatures" where the AI shows its reasoning steps.
• Higher Accuracy: Reduced errors in math, coding, and logic puzzles due to internal self-correction.
• Dynamic Visuals: Generate on-the-fly infographics and interactive tools instead of just text.
• Deep Research: Handle queries that require synthesizing data from dozens of sources.

Step-by-Step Instructions

Here's how to do it.

On Desktop (Web)

1. Navigate to Google Search, www.Google.com.
2. Select AI Mode.
3. Select 'Thinking with 3 Pro' from the AI Mode dropdown.
4. Or Navigate to gemini.google.com.
5. Select 'Thinking' or 'Pro'.
6. Type a complex prompt (e.g., "Create a 7-day meal plan for a family of four, optimizing for zero food waste by reusing ingredients across multiple recipes").
7. Google generates the output.

On iOS & Android (Gemini App)

1. Open the Google app or Gemini app.
2. Tap the Model Switcher pill button near the bottom of the screen.
3. Choose 'Thinking' (indicated by a brain icon).
4. Enter your prompt.

Pros and Cons

Pros

• Superior Reasoning: Solves complex math and logic riddles that stump standard models.
• Self-Correction: If the model detects a logic error during its "thought process," it backtracks and fixes it before showing you the result.
• Interactive Outputs: Can render playable code snippets or data visualizations directly.

Cons

• Slower Speed: Responses can take 10–30 seconds to start while the model "thinks."
• Usage Limits: Free users have a limited number of "Thinking" queries per day; heavy use requires a Google AI Ultra subscription.
• Overkill for Chat: Not necessary for simple questions like "What is the capital of France?"

Feature Access

• Availability: Currently available globally in English to all users on the Gemini App and Web.
• Free Tier: Includes a daily cap of "Thinking" prompts (resets every 24 hours).
• Subscription: Google AI Ultra subscribers get significantly higher limits and priority access during peak times.
• Rollout: Full "Deep Think" features rolled out as of December 2025.

Score

Criterion  |  Score (0–10)  | Justification

Value 9

Essential for complex tasks where accuracy matters more than speed.

Usability 8

The toggle is easy to find, though the wait time requires patience.

Wow Factor 10

Watching the AI "self-correct" its own logic in real-time is genuinely futuristic.

Total: 27/30  🌟 Excellent

This is a massive leap forward for power users, offering a level of transparency and reliability that makes it a viable alternative to hiring a research assistant.

Key Takeaways

Use Thinking with 3 Pro for math, coding, and complex planning, not for casual chat.

Expand the "Thinking" dropdown to verify how the AI arrived at its answer.

Free users should save their daily "Thinking" allowance for their hardest problems.
