What’s Really Changing in Development and Why It’s Not a Cursor Killer / Habr

On November 18, 2025, Google unveiled a combination of two products: the new flagship model Gemini 3 Pro and the agent-first IDE Google Antigravity. The classic concept of “LLM + editor plugin” has its limitations: large monorepos, complex CI/CD pipelines, multimodal artifacts (screenshots, videos, logs, PDFs), and traceability requirements don’t fit well into a chat window next to the editor. What was needed was a combination: a model that can confidently “think” and understand different modalities, and an environment that plans, executes, and clearly visualizes the work of agents. Google answered our prayers and presented just such a combination: Gemini 3 Pro + Antigravity.

Headlines like “Cursor is dead,” “a new era of development,” and “agents will do everything for you” immediately flooded the feeds. In this article, we’ll break down what exactly Google has launched, how Antigravity differs from Cursor, which development scenarios are already changing, and where it’s still too early to abandon your familiar stack.

What Exactly Did Google Roll Out?

1) Gemini 3 Pro – a multimodal model with a long context, optimized for complex reasoning, agentic scenarios, and code. I recommend checking out the Gemini 3 Developer Guide

2) Google Antigravity – a new agent-first IDE, designed from the ground up not as an editor with code suggestions, but as an environment for multiple AI agents to work on a real project.

Moreover, Antigravity is not a plugin for VS Code (like Cursor or Copilot extensions), but a separate application based on a fork of VS Code, tailored for multi-agent scenarios. Gemini 3 Pro and Antigravity are designed as a unified architecture for agentic development.

Officially, Gemini 3 Pro is “the smartest model from Google” and “the world’s best multimodal model for agentic scenarios and vibe-coding”, according to the Google blog. It’s…
