Gemini 3 is here! Introducing the key improvements along with use cases

Gemini - Google の AI

Hello, this is the official note editorial department for Google's AI, "Gemini".

Have you already tried the latest Gemini model, "Gemini 3"?

As of December 12, Gemini 3 is only available as Gemini 3 Pro, but you can use it in the Gemini app, Google AI Studio, Vertex AI, and more.
Its multimodal capabilities for understanding images and videos, as well as its reasoning abilities, have evolved significantly, allowing it to help you solve more complex problems than ever before.

【 Updated 2025/12/19 】
Following the recently announced "Gemini 3," the highest-performing model in Google's history, we have released Gemini 3 Flash, which is more accessible for everyday use.
With Pro-level deep reasoning capabilities and the processing speed unique to Flash, it combines both in an exquisite balance to instantly understand your intent. It accelerates every task, such as learning, planning, and coding, at unprecedented speeds.
Gemini app Experience it in the high-speed mode (3 Flash) and thinking mode (3 Flash with Thinking), as well as in Google AI Studio.

This allows you to get more accurate results even with short prompts. By evolving beyond simply reading text and images to understanding the situation and context, it supports your learning, work style, and creativity more than ever before.

In this article, we will introduce what you can specifically do with the Gemini app now that Gemini 3 has arrived, including concrete use cases and prompts!

※The explanations regarding the use of generative AI, including Gemini, are for illustrative purposes. Please verify the accuracy of the actual response results yourself.


How to use Gemini 3 Pro in the Gemini app

The model selection has changed from the previous way of choosing Gemini models as follows, but Gemini 3 Pro can be used via "Thinking mode".
◯ Gemini 2.5 Flash → High-speed mode
◯ Gemini 2.5 Pro → Thinking mode (equipped with 3 Pro)

The Gemini app is now even smarter and easier to use

The powerful Gemini 3 is now available in the Gemini app you use every day.

It's not just an improvement in performance; it supports our daily lives to be more creative and intuitive. Here, we introduce three changes realized by Gemini 3.

1. Improved video analysis capabilities 🎥

Gemini's ability to recognize visual information has greatly improved. It can now understand the events happening within a video in more detail than previous video analysis.

For example, you can find specific scenes in long videos, have it analyze form or play improvements from sports match footage, or decipher complex situations.

2. Turn handwritten notes into moving "shapes" with the evolved Canvas ✏️

"Gemini Canvas," which supports brainstorming and coding, has also had its features expanded by Gemini 3. By uploading "handwritten notes (wireframes)" drawn on paper notebooks or tablets, you can convert them into functional website or app code.

3. More intuitive responses with the "Generative Interface" 📱

Gemini 3 features a capability called the "Generative Interface," which generates the optimal display format (UI) on the fly to match the content of your query (*Note: As this is currently in the experimental stage, it may appear as "Visual Mode" or "Dynamic View" depending on your account).

  • When you want to organize information: It presents it in an easy-to-read table or card format.

  • When you want to know a location: It displays an interactive map.

  • When you want to know the steps: It creates a step-by-step visual guide.

You can create travel schedules, or...

You can learn about historical backgrounds while having works summarized for you.

What can you do with Gemini 3?

Since the release of Gemini 3, many creative "Gemini use cases" have been posted on social media.

In this article, we have picked up and introduced some of the most unique and interesting examples from posts by creators who are trending on X (formerly Twitter).

From creating diagrams to 3D simulations and full-scale game development, we hope this will be an opportunity for you to discover new things you didn't know you could do with Gemini.

Instantly turn complex information into "diagrams" 📊

"It's hard to understand with just text..." You might be able to solve that problem using the Gemini 3 × Canvas feature. It converts complex concepts or data into easy-to-understand visual diagrams.

With the Canvas feature selected, try entering the following prompt:

Research [Topic] and summarize it in a single diagram!

Alternatively, by inputting information you have already researched via text, documents, or PDFs, Gemini 3 will understand the content and turn it into a diagram.

Below is an example of researching how to make curry and turning it into a diagram. You can create beautiful diagrams with a very simple prompt, so please give it a try.

Look up how to make curry and summarize it in a single diagram!

By using Gemini 3's multimodal capabilities and advanced reasoning, you can neatly organize and visualize even complex topics. It seems like it will be a powerful ally for creating materials and learning!

Experience '3D simulation' in the chat screen 🧪

By combining Gemini's coding capabilities with the Canvas feature, you can also create physics calculations and mathematical simulations.

You can create a 3D Excel simulator with a prompt, or even input a floor plan as an image and convert it into a 3D model.

It can also be used for brainstorming in educational settings or the early stages of research. For example, let's create a '3D simulation to explain the Earth's rotation to students'.

Create a 3D simulation to explain the Earth's rotation to students! Draw the world map clearly too!

Instantly turn ideas into 'games' 🎮

You can now bring 'I wish there was a game like this' to life without deep programming knowledge. Through dialogue with Gemini 3, you can now create more advanced games than ever before.
For example, you can input a character image and create a 3D running game where the character runs, or

You can create a game where you tilt the board to guide a ball from a maze to the goal,

You can also create shooting games like Space Invaders.

Create a game to learn English in a fun way! I want to memorize English words every day, but I can't keep it up. Make it a game that I'll want to play every day without thinking!

By continuing to dialogue with Gemini 3, not just generating programming code, but also building worldviews and establishing rules, your ideas will take shape.

Building practical Web pages 🌐

Even without coding skills, you can create a prototype of a practical website with just a prompt. Please experience the speed and fun of being able to intuitively shape what you want to create with 'Vibe Coding'.

I want to create a web page to launch a fashion site. Build me a stylish website with a Y2K color motif! I don't need product images, so please focus on the layout and page design!

More intuitive answers with the "Generative Interface"

Interacting with Gemini has evolved beyond just exchanging text. The "Generative Interface" feature provided by Gemini 3 optimizes the display format of answers on the fly to match your questions.

For example, the form of the answer changes as follows:

・Product comparison: Instead of a text-only list, it displays easy-to-read, organized "comparison cards."

Summarize the differences between American English and British English!

・Location search: It generates and presents an interactive "map" on the spot.

I want a map of tourist attractions in each prefecture of Japan!

It is a more intuitive experience where Gemini prepares the appropriate interface in real-time to match the form of the answer you are looking for.

Note that this feature is currently in the experimental stage (Labs), so depending on your account, it may appear as "Visual Mode" or "Dynamic View."
Please try it out for yourself.

Embark on a new creative journey with Gemini 3

So far, we have introduced various examples created using Gemini 3.

Diagrams that organize complex information, 3D simulations that deepen understanding through movement, and game or website creation that expresses your own unique worldview.

What these have in common is that Gemini 3's "ability to deeply understand context" connects with your intuitive ideas to bring them to life.

If you have a desire to "do this" or "try that," we have entered an era where you can make it happen with Gemini 3, even if you aren't confident in your professional skills.

The evolved Gemini app is available for anyone to use for free. Please make Gemini 3 your partner and start your new creative journey.
