The Power of Gemini 3.1 Pro
Google officially released Gemini 3.1 Pro on February 19, 2026, marking a significant advancement in its AI model series. This latest iteration, a progression from the Gemini 3 series, aims to tackle complex problems that demand more than simple answers. A core strength of Gemini 3.1 Pro lies in its enhanced reasoning capabilities, allowing it to perform logical deductions with greater accuracy.
Performance benchmarks clearly highlight this improved logical deduction. For instance, in the ARC-AGI-2 Benchmark, which evaluates a model's ability to solve novel logic patterns, Gemini 3.1 Pro achieved an impressive score of 77.1%. This figure represents more than double the performance of its predecessor, Gemini 3 Pro, which scored 31.1%.

In the ARC-AGI-2 Benchmark, Gemini 3.1 Pro achieved a score of 77.1%, more than double its predecessor, Gemini 3 Pro.
Furthermore, in Humanity’s Last Exam, a test for advanced domain-specific knowledge, Gemini 3.1 Pro scored 44.4%, surpassing OpenAI’s GPT 5.2 at 34.5%. The model also leads the rankings in the APEX-Agents Benchmark. While Claude Opus 4.6 still holds a slight edge in pure text-based tasks on the Arena platform, and models like Opus 4.5 and GPT 5.2 High occasionally outperform it in coding scenarios, Gemini 3.1 Pro’s overall performance impressively demonstrates its advanced capabilities across the board.
Access and Application of Gemini 3.1 Pro
Gemini 3.1 Pro is currently available as a preview for developers through the Gemini API in Google AI Studio, Gemini CLI, Google Antigravity, and Android Studio.

Developers can access Gemini 3.1 Pro through various platforms, including Android Studio.
For businesses, it can be accessed via Vertex AI and Gemini Enterprise. End-users can engage with Gemini 3.1 Pro through the Gemini App and NotebookLM. Users with Google AI Pro and Ultra subscriptions benefit from elevated usage limits within the Gemini App and NotebookLM. Notably, the API usage price remains consistent at two dollars per million input tokens.
A significant feature of Gemini 3.1 Pro is its context window, supporting up to one million input tokens. This allows for the analysis of exceptionally lengthy documents or entire code libraries. The model also boasts enhanced token efficiency and a new "thinking mentality." A `MEDIUM` thinking level, adjustable via the `thinking_level` parameter, now optimizes the balance between cost, performance, and speed. Uniquely, Gemini 3.1 Pro can comprehend vast datasets and intricate problems drawing from diverse information sources, including text, audio, images, videos, PDFs, and entire code repositories.
The model comprehensively supports various inputs such as text, code, images, audio, video, and PDF, with text as the output. Its maximum input token limit is an impressive 1,048,576, and the maximum output token limit is a substantial 65,536. Supported functionalities include Batch API, Caching, Code execution, File Search (within AI Studio), Function Calling, Search Grounding, Structured Outputs, Thinking, and URL context. However, it does not currently support audio generation, grounding with Google Maps, image generation, or Live API. A specialized version, `gemini-3.1-pro-preview-customtools`, caters specifically to developers utilizing Bash and custom tools, optimized for agent-based workflows. The model's knowledge cut-off date is January 2025.
Innovative Features and Current Availability
One notable innovation in Gemini 3.1 Pro is "Vibe-Coding," which enables the generation of animated Scalable Vector Graphics (SVGs) directly from text prompts. These SVGs, being code-based, maintain minimal file sizes while offering full scalability. Gemini 3.1 Pro can further process and prepare complex data, such as converting ISS telemetry data into live visual dashboards. It can also program immersive 3D experiences and translate literary works into modern website code. The model offers improved Software Engineering (SWE) and agent functions, exemplified in finance and spreadsheet applications.
For developers seeking to utilize Gemini 3.1 Pro with Google Antigravity, ensuring the latest version of Antigravity is crucial. An error message like "Gemini 3.1 Pro is not available on this version," often signals a compatibility issue with outdated software. Many users have resolved this by simply updating Antigravity, sometimes via `apt`, or by running an installer without prior uninstallation to retain existing settings.
