Google launched Gemini 3.1 Pro on February 19, bringing the core reasoning breakthroughs from its experimental Deep Think model to everyday applications. The new model scores 77.1% on the ARC-AGI-2 benchmark—more than double the reasoning performance of Gemini 3 Pro—and is now rolling out across consumer and developer platforms.
What Makes Gemini 3.1 Pro Different
Gemini 3.1 Pro represents Google’s first “.1” increment update, marking a departure from previous patterns of waiting for mid-year “.5” refreshes. According to 9to5Google, this faster release cadence signals accelerating AI development at Google.
The model is designed for tasks where simple answers won’t cut it. Google positions 3.1 Pro for complex problem-solving requiring advanced reasoning, like synthesizing data from multiple sources, explaining complicated topics visually, or creating step-by-step plans for ambitious creative projects.
Performance Benchmarks and Capabilities
The standout achievement is Gemini 3.1 Pro’s ARC-AGI-2 score of 77.1%. This benchmark tests whether AI models can solve entirely new logic patterns rather than memorizing training data. According to Android Headlines, doubling performance on this specific test demonstrates genuine reasoning improvements, not just incremental gains.
The model supports a 1 million token context window and can process up to 900 images, 8.4 hours of audio, or one hour of video in a single prompt. Google DeepMind’s model card confirms Gemini 3.1 Pro handles text, audio, images, video, PDFs, and entire code repositories.
Where You Can Use Gemini 3.1 Pro
Google is rolling out 3.1 Pro across its ecosystem starting today. For consumers, the model is available in the Gemini app for everyone, with Google AI Pro and Ultra subscribers getting higher usage limits. Researchers gain access through NotebookLM, exclusively for Pro and Ultra subscribers.
Developers can access Gemini 3.1 Pro in preview through the Gemini API in Google AI Studio, Vertex AI, and Android Studio. According to TechCrunch, Google Antigravity—the company’s agentic development platform—also supports the new model.
Focus on Agentic Workflows
Google describes the 3.1 Pro release as advancing “agentic workflows”—systems where AI can complete multi-step tasks with greater independence. The Gemini Team stated they’re releasing 3.1 Pro in preview to “validate these updates and continue to make further advancements in areas such as ambitious agentic workflows.”
According to gHacks, demonstration examples showed the model generating a complete interactive bird simulation with executable code, controls, and dynamic sound behavior from a single prompt—reflecting improved planning capabilities.
Practical Applications
The advanced reasoning translates to real-world use cases. When you need clear visual explanations of complex topics, Gemini 3.1 Pro can break down difficult concepts with diagrams and examples. For data synthesis, the model combines information from disparate sources into coherent single views.
Creative projects benefit from step-by-step planning capabilities. According to Medium reviewer Barnacle Goose, Gemini 3.1 Pro introduces a three-tier thinking system—low, medium, and high computational modes—allowing developers to balance response speed against reasoning depth.
How It Compares to Competitors
Gemini 3.1 Pro enters a crowded market competing against OpenAI’s GPT-5.3-Codex, Anthropic’s Claude Opus 4.6 and Sonnet 4.6, and other frontier models. While Google hasn’t published direct comparison benchmarks, the ARC-AGI-2 score represents a significant milestone in abstract reasoning.
The 1 million token context window and expanded output capacity of 65,536 tokens address previous limitations. Earlier Gemini 3 Pro versions reportedly truncated code generation around 21,000 tokens, frustrating developers working on large codebases.
Availability and Pricing
Google hasn’t announced pricing changes for Gemini 3.1 Pro. The model rolls out immediately for existing Gemini users, with Pro and Ultra subscribers receiving priority access and higher usage caps.
The preview designation signals Google is gathering feedback before general availability. This approach follows industry patterns of testing advanced models with early users to identify issues before wider deployment.
What This Means for AI Development
The Gemini 3.1 Pro launch reflects several important trends. First, the accelerated release schedule shows major AI labs are iterating faster than traditional software development cycles. Second, the focus on reasoning over raw model size suggests the industry is prioritizing quality over quantity.
Third, the emphasis on agentic workflows signals where AI development is heading—toward systems that can work more independently rather than just responding to prompts. Fourth, making advanced capabilities available across consumer and enterprise products demonstrates Google’s platform strategy for AI.
For developers and businesses, Gemini 3.1 Pro offers improved tools for building applications requiring complex reasoning. For consumers, the upgrade brings more capable AI assistance to everyday tasks through the Gemini app.
The real test will be whether users notice meaningful improvements in their daily interactions with Gemini. Benchmark scores matter, but practical performance on actual tasks determines whether 3.1 Pro represents genuine progress or just incremental refinement.
