What can Google’s Gemini 3 AI do?

Luke Meredith

Google’s Gemini 3 is the newest step forward in artificial intelligence (AI), and it is built to do much more than just chat.

Earlier versions of Gemini focused on understanding text and images together, then on stronger reasoning and tool use. Gemini 3 takes this further by acting more like a builder and planner than a simple chatbot. It can read information, think about it, call tools, write and run code and even create interactive interfaces that feel like small apps.

One of its standout features is called Deep Think. Instead of rushing to give an answer, Gemini 3 can slow down and spend more time working through complex problems. This makes it better at solving tricky math, scientific questions and multi-step plans.

Another exciting ability is Generative UI. This means Gemini 3 can not only explain something, but also design a whole interactive page around the answer. For example, if you ask it to explain how the heart works for a teenager, it could build a mini learning site with diagrams and quizzes.

Gemini 3 is also multimodal, which means it can handle text, images, audio, video and even PDFs all in one place. With its large context window, it can work with long documents like research papers or lecture transcripts. This makes it useful for turning messy notes into clear outlines, study plans, and flashcards.

Developers benefit too, because Gemini 3 can read code, suggest improvements and even scaffold entire projects. In tools like Android Studio or Google’s Antigravity platform, it acts like a teammate who sets up layouts, components and automation rather than just filling in snippets.

You will see Gemini 3 across Google products. In the Gemini app, it powers richer responses like study helpers and travel planners. In Google Search, it supports an AI mode that gives tables, step-by-step breakdowns and visual explanations instead of plain text.

Businesses may notice Gemini 3 contributing to how generative engine optimisation (GEO) presents their websites’ content on search result pages. For developers, it is available through the Gemini API and in coding environments, where it can generate interactive experiences.
