Google launches Gemini 3.1 Pro with enhanced reasoning capabilities
Google has launched Gemini 3.1 Pro, an updated AI model demonstrating improved reasoning skills. The model reportedly performs twice as well as its predecessor in complex logic tests.

What happened?
Google has introduced Gemini 3.1 Pro, a new version of its AI model. According to the announcement, the model has advanced in fundamental reasoning and is described as a smarter neural network for complex tasks. In the ARC-AGI-2 benchmark, Gemini 3.1 Pro achieved 77.1%, which is more than double the score of the previous Gemini Pro version.
Key facts
| Modell | Gemini 3.1 Pro |
|---|---|
| ARC-AGI-2 poäng | 77,1% |
| Prestandaökning jämfört med Gemini 3 Pro | Mer än dubblerad |
| Lansering | Minst 4 månader sedan (publicerat 185741) |
”The new version has advanced in fundamental reasoning. It is a smarter and more capable neural network for solving complex tasks”
”Gemini 3.1 Pro is suitable for tasks where a simple answer is insufficient — it employs advanced reasoning to tackle the toughest challenges”
Why it matters
This launch is significant as it indicates progress in the ability of AI to perform advanced logical reasoning. An improved capacity to solve novel logical patterns could lead to more capable AI systems that can handle more complex and nuanced problems. This is crucial for the development of AI applications across many sectors.
Who is affected?
The launch primarily affects developers, who gain access to the model via the Gemini API, Google AI Studio, and Android Studio. Enterprise clients, through Vertex AI and Gemini Enterprise, as well as the general public via the Gemini app and NotebookLM, are also impacted through improved AI functionality. More capable models may lead to new applications and services.
Impact on the EU
Gemini 3.1 Pro is available globally, which includes the EU market. Availability for EU users via the Gemini app and NotebookLM, as well as for developers and business customers, means that AI stakeholders within the EU can benefit from the enhanced features.
What else you should know
The ARC-AGI-2 test specifically evaluates a model's ability to solve novel logical patterns, which differs from traditional benchmark tests.
