Google has just released Gemini 3.1 Pro Preview, and we're excited to announce that it's available today on Cencori.

As Google's newest flagship offering, Gemini 3.1 Pro represents a significant leap forward in reasoning capabilities and agentic engineering usability.

What's New?

Gemini 3.1 Pro isn't just a minor iteration. It introduces several key enhancements that make it a powerhouse for complex AI applications:

1. Enhanced Reasoning

3.1 Pro scores higher on complex problem-solving benchmarks, providing more accurate and nuanced responses for intricate logic tasks.

2. Massive 1M Context Window

Process entire code repositories, massive PDF documents, or hour-long videos in a single request. With a 1 million token context window, you can feed the model everything it needs to know without worrying about hitting limits.

3. Optimized for Agentic Workflows

The new gemini-3.1-pro-preview-customtools endpoint is specifically designed for developers building AI agents. It features improved performance when handling simultaneous, multi-step tool calls and bash operations.

Use it Today

You can start using Gemini 3.1 Pro through the Cencori SDK immediately.

import { Cencori } from '@cencori';
 
const cencori = new Cencori();
 
// Traditional chat
const response = await cencori.ai.chat({
  model: 'gemini-3.1-pro-preview',
  messages: [{ role: 'user', content: 'Analyze this repo architecture...' }]
});
 
// Specialized tool use for agents
