Google has officially launched Gemini 3, and it is a massive leap forward from previous versions. With new features like “Deep Think” reasoning, Generative UI (where the AI builds interactive dashboards for you), and the Google Antigravity coding platform, there is a lot to learn.
But with so many features released at once, where should you start?
We’ve scoured YouTube to find the best tutorials, demos, and reviews. Whether you are a developer looking to code with “Vibe Coding” or a casual user wanting a better personal assistant, these 5 videos will get you up to speed in minutes.
Here are the top 5 guides to mastering Gemini 3.
1. The Best “Zero-to-Hero” Guide

- Video: Gemini 3.0 Pro: Greatest Model Ever! (Fully Tested)
- Best For: Tech Enthusiasts & Optimizers
Do you want to know if Gemini 3 is actually smarter than GPT-4? The World of AI channel pushes the model to its absolute limits with complex logic puzzles and stress tests. This is essential viewing if you plan to use AI for complex work rather than just casual conversation.
Key Takeaways:
- “Deep Think” Mode: See how the new reasoning toggle works to “plan” answers before writing them.
- Multimodal Analysis: Demonstrates uploading PDFs and sketches to have Gemini turn them into summaries or code.
- Benchmarks: A breakdown of how the model is cheaper and faster than competitors while maintaining high performance.
3. The Developer’s Crash Course
- Channel: Prompt Engineering
- Video: Gemini 3 Pro: It was worth the wait!!!
- Best For: Coders & Software Engineers
Gemini 3 introduced “Google Antigravity,” a new platform specifically for building AI agents and coding. This video dives deep into the technical side, showing how developers can use the expanded context window to analyze massive codebases.
Key Takeaways:
- Google Antigravity: A first look at the new agentic IDE (Integrated Development Environment).
- Refactoring Code: Watch the model identify bugs in legacy code and rewrite them in real-time.
- Ethical Reasoning: The host tests the model’s ability to handle nuanced ethical scenarios without “refusing” to answer valid questions.
4. The Official Vision
- Channel: Google
- Video: A new era of intelligence with Gemini 3
- Best For: A High-Level Overview
Sometimes it helps to see exactly what the creators intended. This official release video is high-production and showcases the “ideal state” of Gemini 3. It’s perfect for understanding the full scope of what is possible, from integration with Google Search to creating interactive simulations.
Key Takeaways:
- Generative UI: The official reveal of how the model creates custom interfaces on the fly.
- Native Integration: Shows how data flows seamlessly between Search, Docs, and Drive.
- Interactive Sims: Demos how to ask for a visual explanation (e.g., “Show me how a black hole works”) and get a playable simulation.
5. The Business & Industry Perspective
- Channel: Valuetainment (PBD Podcast)
- Video: Gemini 3 CRUSHES ChatGPT
- Best For: Business Leaders & Investors
This isn’t a tutorial on buttons, but a tutorial on strategy. The PBD Podcast team breaks down the competitive landscape, comparing Gemini 3 directly against ChatGPT and Perplexity in live speed tests.
Key Takeaways:
- Speed Comparisons: Reacting to Gemini 3’s near-instant response times.
- The “Agent” War: A discussion on why the future is “AI Agents” doing work for you, and why Google’s ecosystem gives it a massive advantage.
- Market Impact: What this release means for the tech industry moving forward.
Summary: Which Video Should You Watch?
| Channel | Best For | Key Feature Highlight |
| Maya Bello | Beginners | Visual Layouts & Agent Mode |

Bonus: Try This “Master Prompt”
Once you have watched the videos, open Gemini 3 and try this prompt to test both its Reasoning and Visual capabilities in one go:
The Prompt:
“Act as a Strategic Operations Manager. I am launching a coffee shop with a $20,000 budget. Analyze the optimal strategy between buying bulk inventory (20% discount) vs. saving cash for marketing. Show your reasoning step-by-step.
Then, based on your strategy, generate an interactive ‘Profit Simulator’ dashboard that visualizes my cash burn rate over 30 days.”
Conclusion
Gemini 3 is more than just a chatbot update; it’s a shift toward AI that can reason, plan, and build interfaces. We recommend starting with Maya Bello’s guide if you are new to these concepts, or jumping straight into Prompt Engineering’s video if you are ready to start building.
