What did Google launch today?

Here’s the quick snapshot of what Google just rolled out:

• Gemini 3, Google’s most intelligent AI model so far
• Gemini 3 Pro in preview, available across multiple Google products
• Gemini 3 Deep Think, a special "enhanced reasoning” mode
• Gemini Agent, a more capable AI assistant that can handle multi-step tasks

What is Gemini 3, in simple terms?

Think of Gemini 3 as Google’s next-generation AI brain.

Previous versions did a lot:

• Gemini 1 introduced strong multimodality (understanding text, images, and code together)
• Gemini 2 & 2.5 improved reasoning and kicked off the "agentic” era, where AI started taking actions, not just answering

Now Gemini 3 puts everything together and levels it up:

• It’s built for deep reasoning: understanding nuance, subtle context, and layered problems
• It better understands what you actually mean, not just the literal words you type
• It’s more capable across text, images, video, audio and code, with a huge context window

You don’t have to feed it long, complicated prompts anymore. You can talk to it more naturally and still get powerful results.

Gemini 3 Pro: The main model you’ll use every day

The first model of the new family is Gemini 3 Pro, released today in preview.

This is the version most people will touch first, through:

• The Gemini app
• AI Mode in Google Search
• Google AI Studio, Vertex AI, Gemini CLI and other developer tools

Gemini 3 Pro brings three big improvements:

1. Smarter reasoning

It’s designed to handle:

• Complex questions
• Multi-step problems
• Advanced topics spanning science, math, research, and more

Instead of surface-level answers, it aims to give structured, thoughtful explanations that help you actually understand.

2. Multimodal power

Gemini 3 Pro isn’t limited to text. It can work with:

• Images
• Video
• Audio
• Code
• Long documents and multiple files together

So you can, for example, upload a paper, a diagram and a video, then ask it to connect the dots and teach you the concepts.

3. Better conversations

Google highlights that Gemini 3 Pro is:

• More direct and concise
• Less "flattery and clichés”
• More like a real thought partner that tells you what you need to know

In other words, less "you’re amazing!” and more "here’s the hard truth and how to fix it.”

Gemini 3 Deep Think: When you need serious brainpower

Alongside Gemini 3 Pro, Google introduced Gemini 3 Deep Think.

You can think of Deep Think as "focus mode” for the model:

• It spends more internal effort on a problem
• It follows longer chains of reasoning
• It’s designed for hard, novel, multi-step tasks, like complex mathematics, tricky logic puzzles, or advanced technical questions

While Gemini 3 Pro is your daily driver, Deep Think is the "bring in the specialist” mode.

Right now:

• Deep Think is being tested with safety and evaluation partners
• It’s planned to roll out to Google AI Ultra subscribers in the Gemini app

Learn anything: Gemini 3 as your personal study partner

One of the most exciting parts of Gemini 3 is how it helps you learn.

Turn messy information into clear learning tools

You can give Gemini 3 things like:

• Handwritten family recipes in different languages
• Long academic research papers
• Video lectures or tutorials
• Screenshots, slides, code snippets

And ask it to:

• Clean them up
• Translate them
• Turn them into:
  • Interactive flashcards
  • Visual diagrams
  • Short summaries at different difficulty levels
  • Step-by-step explainers

For example:

"Here are three papers on RNA polymerase and a lecture link. Turn this into a visual study guide plus 20 quiz questions.”

Gemini 3 can combine all of that into a tailored learning experience.

Learn from your own life

Gemini 3 also uses multimodal understanding in more personal ways. You could:

• Upload a video of your pickleball match
• Ask Gemini 3 to:
  • Analyze your gameplay
  • Point out where you’re making mistakes
  • Create a training plan to improve

This is where "AI + real life” starts to feel very real.

Smarter Search with AI Mode

In AI Mode in Search, Gemini 3 powers richer experiences:

• Immersive visual layouts
• Interactive tools and simulations
• Dynamic explanations generated on the fly based on your question

So instead of a simple paragraph, you might get a mini app-like layout that helps you explore a topic.

Build anything: Gemini 3 for developers, makers & creators

If you build things for the web, apps, or games, Gemini 3 is a big upgrade.

The best "vibe coding” model Google has made so far

Google calls Gemini 3 its best vibe coding and agentic coding model yet.

In practice, that means:

• You can describe what you want in normal language
• Gemini 3 can generate:
  • Frontend UIs
  • Backend logic
  • APIs
  • Games
  • Tools and dashboards
• It’s better at understanding style, structure, and "vibes”
  • "Make this look like a retro sci-fi game menu”
  • "Give this dashboard a clean, minimalist, professional feel”

Richer, more interactive projects

In tools like Google AI Studio, Gemini 3 can help you:

• Build a retro 3D spaceship game
• Create 3D voxel art purely with code
• Design and code playable sci-fi worlds with shaders
• Generate and refine complex web interfaces with interactions, animations and logic

And because it’s improved as an agentic coder, it’s better at:

• Using tools like terminals
• Running and testing code
• Fixing its own mistakes
• Handling more complex instructions

Google Antigravity: An AI-native development experience

One of the biggest developer-focused announcements is Google Antigravity.

You can think of Antigravity as:

A new development environment where AI agents are first-class citizens, not just assistants.

Inside Antigravity:

• Gemini 3 Pro and other models get direct access to:
  • The code editor
  • The terminal
  • A browser
• Agents can:
  • Plan full tasks
  • Write and refactor code
  • Run commands
  • Open pages
  • Validate and debug their own work

So instead of saying:

"Write me a React component.”

You might say:

"Build a basic flight tracker web app that shows live delays, test it, and clean up the UI.”

The agent can then:

1. Break down the task
2. Create the project structure
3. Write code
4. Run it in the terminal
5. View it in the browser
6. Iterate based on errors and results
7. Show you what it did via structured outputs

It’s a big step toward task-level development, where you describe outcomes, and the AI handles more of the steps.

Plan anything: Gemini 3 as an actual "doer,” not just a talker

Gemini 3 isn’t only for Q&A. It’s built to plan and execute.

Google has been investing heavily in long-horizon planning: the ability to stay on track over a long series of actions without forgetting the goal or drifting.

This shows up in a few places:

Gemini Agent

With Gemini Agent, powered by Gemini 3, the AI can:

• Handle multi-step workflows like:
  • Organizing your Gmail inbox
  • Managing recurring tasks
  • Booking local services
  • Coordinating things across your Google apps
• Use tools more consistently and stick to your instructions over time

Think less "chatbot” and more "junior assistant” that follows through.

Gemini Agent is first rolling out to Google AI Ultra subscribers in the Gemini app, and will expand to more products over time.

---

Built with responsibility in mind

Google is also emphasizing that Gemini 3 is its most secure and thoroughly evaluated model so far.

Key themes include:

• Stronger safeguards against:
  • Prompt injection
  • Misuse for hacking and cyberattacks
  • Over-agreeing with the user at the expense of truth
• Extensive internal testing and external evaluations by independent experts and safety organizations
• Ongoing monitoring and updates as new risks appear

The message is clear: Google wants Gemini 3 to be powerful and trustworthy.
