1. 77.1% on ARC-AGI-2 Benchmark — 2x Reasoning Performance

Gemini 3.1 Pro's most significant technical achievement is scoring 77.1% on the ARC-AGI-2 benchmark. ARC-AGI-2 is one of the most challenging benchmarks that evaluates how well AI can solve completely new logical patterns. This score represents more than double the reasoning performance compared to Gemini 3 Pro.

This benchmark measures true logical reasoning capabilities, not simple memorization or pattern matching. At 77.1%, this ranks among the top results for publicly released commercial AI models, demonstrating that Gemini 3.1 Pro serves as a foundation for evolving beyond simple chatbots into Agentic AI.

2. Code-Based Animation and SVG Generation

Gemini 3.1 Pro can directly generate animated SVGs for websites using only text prompts. Unlike pixel-based images, code-based SVGs remain crisp at any resolution and have much smaller file sizes. This becomes a powerful productivity tool for frontend developers and designers.

3. Complex Data Synthesis and Visualization

The ability to synthesize vast amounts of data into a single view and visually explain complex scientific topics has been significantly enhanced. Researchers and analysts can now integrate multiple data sources and derive insights much more efficiently with Gemini 3.1 Pro.

4. Still in "Preview" Stage — Goal to Expand Agentic Workflows

Google has released 3.1 Pro in the "preview" stage and is collecting feedback. The ultimate goal is to further advance agentic workflows. In other words, AI is evolving beyond simply generating answers to independently planning and using tools to complete complex tasks.

Practical Tips for Developers

Getting Started with Gemini API

You can test the gemini-3.1-pro-preview model for free at Google AI Studio (aistudio.google.com). After obtaining your API key, use it as follows:

import google.generativeai as genai

genai.configure(api_key="YOUR_API_KEY")
model = genai.GenerativeModel("gemini-3.1-pro-preview")

response = model.generate_content(
    "Solve a complex math problem step by step: ..."
)
print(response.text)

Research Integration with NotebookLM

Using NotebookLM equipped with Gemini 3.1 Pro, you can upload PDFs, papers, and reports and request in-depth analysis. Google AI Pro subscribers can process more documents with longer context.

Using Gemini CLI for Terminal AI

Developers can install Gemini CLI and interact directly with Gemini 3.1 Pro in the terminal for code writing, debugging, and documentation generation:

npm install -g @google/gemini-cli
gemini --model gemini-3.1-pro-preview "Tell me how to optimize React components"

The Significance of Gemini 3.1 Pro — Changing AI Competitive Landscape

The emergence of Gemini 3.1 Pro carries meaning beyond a simple model update. With a 77.1% score on ARC-AGI-2, it now possesses reasoning capabilities that rival the GPT series and Claude series. In particular, competition in the agentic AI space is intensifying.

Google is simultaneously rolling out Gemini 3.1 Pro across consumer, developer, and enterprise sectors, rapidly improving AI experiences across its entire ecosystem. The tight integration with Google Antigravity IDE and Vertex AI creates strong competitiveness in the enterprise agent solutions market.
