Hello! This is the AICU media editorial department. On February 20, 2026, Google announced its highly anticipated latest model, "Gemini 3.1 Pro." Further refined from the previous model, Google boasts that this model is a "new baseline for complex problem-solving." What makes it so amazing? What kind of impact will it have on us AI creators and developers? Based on the official X (@Google) announcement thread, we have summarized the awesomeness of Gemini 3.1 Pro in an easy-to-understand manner!

Today, we’re releasing Gemini 3.1 Pro.

It’s the same core intelligence that powers Gemini 3 Deep Think, now scaled for your practical applications. It’s a smarter model for your most complex tasks.

What is "Gemini 3.1 Pro"? ~The ultimate brain in a practical size~

In a nutshell, Gemini 3.1 Pro is "a model that optimizes the core intelligence of Gemini 3 Deep Think for practical applications." In other words, it inherits the intelligence of "Deep Think," which takes time to think deeply, but has been scaled down so that we can use it smoothly in our daily tasks and app development. It is truly the "strongest practical model."

Reasoning ability explodes! A shocking "77.1%" on ARC-AGI-2

The most noteworthy aspect of this update is the dramatic improvement in the AI's "reasoning ability." It recorded an astounding score of 77.1% on the benchmark "ARC-AGI-2," which measures the ability to solve completely new logic patterns. This is more than double the performance of the previous model, Gemini 3.

Gemini 3.1 Pro is our new baseline for complex problem-solving.

This model represents a major leap in core reasoning, verified by a 77.1% score on the ARC-AGI-2 benchmark — which tests the ability to solve brand- new logic patterns.

What is ARC-AGI-2?

It seems to solve games like this.

I had Gemini 3.0 Pro solve it.

This is an ARC-AGI puzzle in the image! I analyzed the rules of the presented examples (Example 1, Example 2) and derived how to solve the test problem. 💡 Puzzle rules: The rule of this puzzle is to "fill in the figure according to the total area (number of pixels) of the 'holes (black pixels)' in the gray figure." Looking at Example 1 and Example 2, the number of black pixels in the frame in the blue-lined "palette (color sample)" matches the number of pixels in the holes in the colored figure. Figures with holes that are not the size of the palette remain gray.

By the way, this answer was incorrect. The correct answer is as follows.

Gemini 3.0 Pro is reflecting, but Gemini 3.1 Pro has completely broken away from the "memorizing past data and answering" phase, and has reached the level of "logically thinking for itself" about unknown tasks.

Must-see for creators & engineers! 3 amazing demos

Google has released three concrete demos in the thread showing the capabilities of Gemini 3.1 Pro. They are all practical and exciting!

① Rapid construction of a real-time ISS tracking dashboard

When Gemini 3.1 Pro was instructed to "create a real-time tracking dashboard for the International Space Station (ISS)," it successfully built a working app.

We asked Gemini 3.1 Pro to build a real-time ISS tracking dashboard. 🛰️

To pull this off, the model had to reason through several logic streams at once to map out a plan:

It is now possible to simultaneously reason through multiple logic streams, such as orchestrating live telemetry (remote measurement data) from public APIs and building responsive UIs with perfect data synchronization, and to create a plan.

② Directly generate "animated SVGs" from prompts!

Here's one that creators can't miss! It is now possible to generate "animated SVGs" that can be used immediately on websites from simple text prompts. Since they are built in pure code (not pixels), the image quality does not deteriorate no matter how much you zoom in, and the file size is extremely small compared to traditional video files. "Try generating an animated SVG of a pelican riding..."

3.1 Pro can even generate website-ready, animated SVGs from a simple text prompt.

Since these are built in pure code — not pixels — they stay crisp at any scale and keep file sizes tiny compared to traditional video.

③ Leave physics calculations to us! "3D starling flock" simulation

Modeling complex systems and sensory interfaces has also become easier. In the demo, an interactive "BOID" "3D starling flock (Murmuration)" simulation environment that responds to hand movements was built. Gemini 3.1 Pro is said to have inferred the "laws of physics" of this flock's movement and translated them into code.

Modeling complex systems and sensory-rich interfaces just got easier. 🧬

We used 3.1 Pro to build this interactive 3D starling simulation.

Portfolio production that maintains the atmosphere of the novel

  1. 1 Pro also brings advanced reasoning capabilities to creative projects. I created a portfolio based on the novel "Wuthering Heights." Not only did it summarize the text, but it also deeply understood the unique atmosphere and tone of the novel, designed a sophisticated UI, and generated code that could be used immediately on the website, capturing the essence of the characters.

3.1 Pro brings advanced reasoning to creative projects, too. 🎨

For example, we used it to build a portfolio based on the novel “Wuthering Heights.”

Release date

The preview version has been released sequentially (rolled out) from February 19, 2026. In the future, it will be further improved and released to the general public (General Availability).

How to use/access (how?) It can be accessed from the following platforms according to the target users.

For general users (consumers)

Gemini app: Provided to Google AI Pro and Ultra plan users with increased usage limits.

NotebookLM: Available only to Pro and Ultra users.

For developers

As a preview version, it can be accessed via Google AI Studio's Gemini API, Gemini CLI, the agent development platform "Google Antigravity," and "Android Studio."

For companies (enterprises)

Provided through "Vertex AI" and "Gemini Enterprise."

It seems that users with paid plans (Pro/Ultra) and developers/enterprise users will be able to use it first!

Summary: A new "baseline" for AI creators is born

The emergence of Gemini 3.1 Pro was not just an update to text-generating AI, but a powerful reminder of its evolution as a "thinking engine." In particular, the significant enhancements in "creative output through code," such as the direct generation of animated SVGs and the construction of 3D simulations involving physics calculations, should be exciting news for AICU readers.

You can leave complex tasks to "Gemini 3.1 Pro." What will you create with this new partner? Please share your ideas on X!
