Gemini

Gemini is a family of artificial intelligence models built by Google. It covers different types of work — from answering questions and writing text to creating images and carrying out multi-step tasks across software and services. Google has been releasing several versions, each designed for a different size of job.

One part of the Gemini family is Gemini Nano, a smaller model that can run directly inside Google Chrome through a feature called window.ai. This means web pages and apps can use basic AI without sending data to a remote server. Another part is Gemini Pro, which is the more powerful version and still tends to perform better in everyday use than the lighter models.

Google recently updated its image model, nicknamed Nano Banana 2.1, which makes pictures that look sharper and costs about half as much as before. Even so, the Pro version is still considered stronger when people test it in real situations.

In October 2026, Google introduced an agentic AI for Gemini aimed at business customers. This agent can plan, carry out, and finish tasks across a company's software systems. Google is rolling it out to enterprise clients first before bringing it to regular users.

Google is also making its AI detection tool available to anyone around the world. The SynthID Detector lets people check whether a photo, video, or other media was generated by AI from Google or its partner companies.

Beyond its own products, Google has placed limits on how other companies, such as Meta, can use Gemini models. The company continues to shape who gets access and under what conditions.
