Key Insights

• Gemini 3.1 Pro is described as Google's flagship model released on February 19, 2026, with a stated reasoning improvement of more than twice that of Gemini 3 Pro. It is available through Google AI Studio, the Gemini app, and the API.
• The stated API price is $2 per million input tokens and $12 per million output tokens, matching the price given for Gemini 3 Pro. Existing Gemini 3 Pro users are therefore presented with the newer model as a free upgrade at the same usage rates.
• ARC-AGI 2 evaluates whether a model can infer and solve unfamiliar logic patterns from examples. Gemini 3.1 Pro reportedly scores 77.1%, compared with 31.1% for Gemini 3 Pro and around 52% for GPT-5.2 in the presented benchmark comparison.
• GPQA Diamond tests graduate-level questions across physics, chemistry, and biology that require multistep scientific reasoning. The reported Gemini 3.1 Pro score is 94.3%, compared with 92.4% for GPT-5.2 and 9.9% for Gemini 3 Pro in the transcript.
• SWE-bench Verified measures whether a model can understand existing GitHub repositories, identify bugs, and implement working fixes. Gemini 3.1 Pro reportedly scores 80.6%, tying Claude Opus 4.6 and supporting its use for production-oriented coding tasks.
• Animated SVG generation combines code structure with spatial and motion reasoning. In the demonstrations, Gemini 3.1 Pro synchronizes a giraffe's legs with bicycle pedals, rotates wheels, adds balancing motion, and produces similarly coordinated movement for a giraffe riding a scooter.
• Video analysis works by examining uploaded recordings with both visual and spoken context. The model identifies what appears at a requested timestamp and can summarize meeting decisions, action items, owners, deadlines, and a mentioned next meeting date from an eight-minute recording.
• Browser application generation can produce functional HTML, CSS, and JavaScript from a single prompt. The examples include a playable Pong game with scoring and restart controls, plus a metric and imperial recipe converter with responsive ingredients, saved preferences, illustrations, and temperature guidance.

Questions & Answers

Q: How can beginners access Gemini 3.1 Pro?

Beginners can access Gemini 3.1 Pro through Google AI Studio, the Gemini app, or the API. The guide describes it as immediately available and as a free upgrade for people already using Gemini 3 Pro. For hands-on experimentation, Google AI Studio is used to upload videos, enter prompts, inspect generated results, and run browser-based code without first building a separate application.

Q: How much does Gemini 3.1 Pro API usage cost?

The stated price is $2 per million input tokens and $12 per million output tokens. Those rates are presented as the same prices charged for Gemini 3 Pro, so the guide characterizes Gemini 3.1 Pro as a free model upgrade for existing users. Actual spending still depends on how many input and output tokens a particular workflow consumes.

Q: How does Gemini 3.1 Pro perform on reasoning benchmarks?

The reported ARC-AGI 2 score is 77.1%, compared with 31.1% for Gemini 3 Pro and around 52% for GPT-5.2. ARC-AGI 2 presents unfamiliar patterns, shows solved examples, and asks the model to infer the underlying rules for new cases. The guide uses this result to support its claim that the model improved substantially at abstract reasoning.

Q: What scientific and multidisciplinary benchmark results are reported?

Gemini 3.1 Pro reportedly scores 94.3% on GPQA Diamond, an evaluation covering graduate-level physics, chemistry, and biology questions that require multistep reasoning. It also reportedly scores 44.4% on Humanity's Last Exam without tools. That exam spans literature, philosophy, history, complex reasoning, and synthesis across multiple disciplines, according to the benchmark explanation provided.

Q: How can Gemini 3.1 Pro analyze an uploaded video?

A user can upload a recording to Google AI Studio and ask what appears at an exact timestamp. In the demonstration, the model identifies a woman in a gray suit, transparent futuristic glasses, a cyan holographic interface, and a webcam overlay at 7 minutes and 32 seconds. The guide presents this as visual frame analysis rather than transcript-only retrieval.

Q: How can Gemini 3.1 Pro summarize work meetings?

Upload a meeting recording and request the key decisions, action items, owners, and deadlines. In the demonstrated workflow, Gemini examines an eight-minute team meeting and returns a formatted summary containing decisions, assigned responsibilities, and the next meeting date. The intended benefit is reducing manual review while preserving who said what and what each person must do.

Q: What kinds of browser applications can Gemini 3.1 Pro build?

Gemini 3.1 Pro can generate HTML, CSS, and JavaScript applications from natural-language requirements. One example is a playable Pong game with game logic, score tracking, and a restart button that reportedly works on the first attempt. Another is a recipe converter with live ingredient updates, metric and imperial measurements, saved preferences, cooking illustrations, and dual-unit oven temperatures.

Q: How can Gemini 3.1 Pro create and revise visual content?

The model can generate SVG illustrations, animated scenes, diagrams, logos, infographics, and visual aids as code. Demonstrations include animated giraffes riding a bicycle and scooter, plus a color-coded content workflow covering idea, research, script, recording, editing, and publishing. Users can revise an output conversationally by requesting changes such as thicker arrows or a different stage color.

Summary & Key Takeaways

• Gemini 3.1 Pro is presented as Google's flagship model released on February 19, 2026. The guide highlights a stated reasoning improvement over Gemini 3 Pro, access through Google AI Studio, the Gemini app, and the API, plus pricing of $2 per million input tokens and $12 per million output tokens.

• The benchmark discussion emphasizes abstract reasoning, scientific problem solving, coding, and multidisciplinary knowledge. Reported results include 77.1% on ARC-AGI 2, 94.3% on GPQA Diamond, 80.6% on SWE-bench Verified, and 44.4% on Humanity's Last Exam without tools, with explanations of what each evaluation measures.

• Practical demonstrations include animated SVG generation, timestamp-specific video inspection, meeting analysis, browser game development, recipe conversion, and workflow diagrams. The model produces editable visual code, extracts decisions and assigned actions from recordings, and builds interactive HTML, CSS, and JavaScript tools from natural-language instructions.
