Google’s latest large‑language model, Gemini 3.1 Pro, is now rolling out across consumer apps and enterprise tools. The upgrade promises double‑digit improvements on logical‑reasoning benchmarks, unchanged pricing, and new features like visual explanations and code‑generated SVGs. Developers can access it via the Gemini API, CLI, and integrated IDEs, while users see it in the Gemini app.
Key Performance Gains
Benchmark Highlights
On the ARC‑AGI‑2 logical‑reasoning test, Gemini 3.1 Pro hit a verified score of 77.1%, more than double the 31.1% achieved by the prior version. In the “Humanity’s Last Exam” assessment, it reached 44.4%, surpassing competing models and showing a clear edge in domain‑specific knowledge.
What the Scores Mean for You
Higher benchmark scores translate into more reliable reasoning when you ask the model to solve complex problems. You’ll notice fewer back‑and‑forth prompts and more concise, accurate answers, especially in multi‑step coding or scientific hypothesis generation.
New Capabilities for Developers
- Unified visual explanations: The model can turn raw data into annotated charts or diagrams on the fly.
- Code‑generated animated SVGs: Simply describe a motion, and Gemini 3.1 Pro outputs scalable vector graphics that stay crisp at any resolution.
- Extended context window: Longer input passages improve chain‑of‑thought reasoning without losing focus.
These features let you turn design briefs into ready‑to‑use assets, cutting down production time and eliminating bulky video files.
Pricing and Availability
Google kept the pricing simple: $2 per million input tokens and $12 per million output tokens. The model is available in preview through the Gemini API, Gemini CLI, Antigravity IDE, Android Studio, Vertex AI, and the Gemini Enterprise suite. If you’re an enterprise customer, you can enable Gemini 3.1 Pro in Vertex AI notebooks to experiment with higher‑order reasoning without waiting for a general release.
Enterprise Impact
Integrating Gemini 3.1 Pro with Google Cloud’s security and compliance stack makes it attractive for regulated industries such as finance and healthcare. Companies can build internal tools, data pipelines, or custom agents that leverage the model’s advanced reasoning while staying within existing governance frameworks.
Practitioner Insights
Early adopters report that the expanded context window reduces the number of iterative prompts needed to reach a satisfactory answer. In Vertex AI notebooks, generating “website‑ready, animated SVGs directly from a text prompt” has cut asset preparation time dramatically. For teams building agentic workflows, the near‑doubling of the APEX‑Agents benchmark suggests smoother hand‑offs between AI‑driven modules.
While Gemini 3.1 Pro is still in preview, the performance jump is evident. Whether the model’s reasoning power delivers a noticeable edge in your daily projects will become clearer as more developers put it through its paces.
