Google Unveils Gemini 3.1 Pro: Breakthrough AI Model Tackles Complex Problem-Solving
Google has launched Gemini 3.1 Pro, a cutting-edge AI model designed specifically for tackling the most demanding complex tasks, marking a significant leap in core reasoning capabilities.[1][2]
Announced on February 19, 2026, this preview release builds on the Gemini 3 series, introducing enhanced intelligence first previewed in the recent Gemini 3 Deep Think update. Unlike previous iterations that used .5 increments for mid-year enhancements, Gemini 3.1 Pro represents Google’s first .1 version, signaling rapid iteration in AI development.[1][2]
Superior Reasoning Performance
The model shines on the ARC-AGI-2 benchmark, achieving a verified score of 77.1%—more than double the performance of its predecessor, Gemini 3 Pro. This benchmark tests a model’s ability to solve entirely new logic patterns, underscoring 3.1 Pro’s advanced problem-solving prowess.[1][2]
Google describes it as a “smarter, more capable baseline for complex problem-solving,” ideal for scenarios requiring deep context, data synthesis, visual explanations of intricate topics, and creative project realization.[1][3]
Immediate Availability Across Platforms
Starting today, Gemini 3.1 Pro rolls out in preview to a wide array of users:
- Consumers: Gemini app and NotebookLM for Google AI Pro and Ultra subscribers, with higher usage limits.[2]
- Developers: Gemini API via Google AI Studio, Gemini CLI, Android Studio, and the new agentic platform Google Antigravity.[2][4]
- Enterprises: Vertex AI and Gemini Enterprise.[3]
Additionally, it’s now in public preview within GitHub Copilot for Pro, Pro+, Business, and Enterprise users, accessible in Visual Studio Code, Visual Studio, github.com, and mobile apps. Administrators must enable it in settings.[5]
Real-World Impact and Customer Feedback
Early adopters report substantial gains. One enterprise user noted up to 15% improvement over Gemini 3 Pro in evaluations, praising its strength, speed, efficiency, and reliability—requiring fewer output tokens for better results.[3]
“Gemini 3.1 Pro represents a clear quality leap… stronger, faster… and more efficient, requiring fewer output tokens while delivering more reliable results.”[3]
In 3D animation pipelines, it excels at edge cases like 3D transformations and rotation orders, resolving long-standing bugs in export processes.[3]
Independent developer Simon Willison tested its SVG animation capabilities, generating detailed visuals like a pelican riding a bicycle after extended thinking time, highlighting improvements over prior models.[6]
Technical Specs and Optimizations
Optimized for software engineering, agentic workflows, precise tool usage, and multi-step execution, Gemini 3.1 Pro supports text, images, video, audio, and PDF inputs with a 1,048,576 token limit (65,536 output).[4]
Pricing matches Gemini 3 Pro at $2 per million input tokens and $12 per million output tokens (under 200K), making it cost-competitive against rivals like Claude Opus 4.6.[6]
| Feature | Details |
|---|---|
| ARC-AGI-2 Score | 77.1% (2x Gemini 3 Pro) |
| Token Limits | 1M+ input / 65K output |
| Supported Modalities | Text, Image, Video, Audio, PDF |
| Key Strengths | Agentic workflows, reasoning, efficiency |
Launch Context and Future Plans
This follows Gemini 3 Pro’s November 2025 preview and Gemini 3 Flash a month later. Google is using this preview to validate updates and advance “ambitious agentic workflows” before general availability.[1][2]
Initial rollout experiences include high demand leading to temporary slowdowns and errors, attributed to launch-day teething issues.[6]
Google emphasizes user feedback driving these improvements, inviting builders to explore its potential in science, research, engineering, and beyond.[2]
Broader Gemini Ecosystem Updates
Alongside 3.1 Pro, the Gemini app gains music generation for all users via Lyria 3 and more prominent chat sharing features. Gemini 3 Deep Think received a major upgrade for practical applications.[1]
As AI competition intensifies, Gemini 3.1 Pro positions Google at the forefront of agentic AI, promising transformative tools for businesses and creators tackling tomorrow’s toughest challenges.
