Gemini 3 Takes Over: Google Ships Its Strongest AI Yet — With Agent Coding, Deep Reasoning & a Billion-Token Memory

November 19, 2025

Google has just made a major leap with the release of Gemini 3 Pro, launching a new era for its AI platform. The model is now available across core Google products — including Search’s AI Mode, the Gemini mobile/web app, AI Studio, and the newly announced “Agent-first” developer tool called Antigravity. 

Here are the biggest take-aways:

Next-Level Reasoning & Multimodal Understanding

Gemini 3 Pro is built to be smarter than its predecessor: Google claims it outperforms Gemini 2.5 Pro on major AI benchmarks, especially in reasoning-heavy tasks. 

It isn’t only better at text — the model supports deep multimodal understanding: text, image, video, audio, and even code. 

There’s also a “Deep Think” mode, aimed at complex analytical tasks, research problems, and planning. Google says it’s rolling this out for its AI Ultra subscribers soon. 

Massive Memory Window

One of the most exciting technical upgrades is the context window — Gemini 3 Pro supports up to 1 million tokens in context, according to logs from Vertex AI. 

This means the model can “remember” much more: long research documents, long-form analysis, or even full conversation histories.

Antigravity: Agent-First IDE

With Gemini 3, Google launches Antigravity, a coding platform where multiple AI agents can operate together. 

These agents can read and write in the code editor, interact with terminals and browsers, and produce “Artifacts” — like plans, task lists, screenshots, and recordings — to verify what they’re doing. 

There are two main views:

  • Editor view (like a normal code IDE, but with AI agent sidebar)

  • Manager view (“mission control” for coordinating agents) 

Gemini 3 Comes to Search & Workspace

For Google Workspace users, Gemini 3 Pro is now selectable in the Gemini app as the “Thinking” model. 

In Google Search (AI Mode), Gemini 3 next-gen is already powering richer, interactive generative UI: dynamic layouts, tables, images, and more. 

Big Consumer Play: Jio’s 18-Month Gemini 3 Offer

In a huge move for adoption, Reliance Jio is bundling Gemini 3 in its Pro Plan for free for 18 months for eligible Unlimited 5G customers. 

This could significantly boost mainstream AI usage across India, giving more people access to Google’s most powerful model yet.

What It Means for You

  • Creators & professionals: You now have access to a model that can help you reason deeply, code smarter, and manage multi-step workflows — not just chat.

  • Developers: Antigravity gives you a way to delegate real tasks to agents, while tracking and verifying what they do.

  • Business users: Gemini in Workspace and Search becomes far more than a search assistant — it’s a “thought partner” that can organize, analyze, and generate.

  • Everyday users (especially in India): Thanks to Jio, advanced AI might soon be just a tap away — democratizing access in a major market.

Prompt Tip of the Day

Prompt:

“You are my research assistant with the power of Gemini 3 Deep Think. Summarize this document (or YouTube transcript, or article thread) in three parts: (1) key arguments, (2) critical assumptions, (3) potential research or next-step ideas. Then propose two follow-up questions.”

Use this when you want strategic insight, not just summaries or to-dos.
