Antigravity 2.0: Google's Agent-First Development Platform

Google has launched Antigravity 2.0 at I/O 2026, transforming its agentic coding tool into a comprehensive platform for developing and managing teams of autonomous AI agents.

What's New in Antigravity 2.0

Antigravity 2.0 is a standalone desktop application available on macOS, Linux, and Windows. The platform is built from the ground up as an agent-first experience, featuring:

• Multi-agent orchestration: Coordinate multiple agents working simultaneously on different tasks
• Dynamic subagents: Automatically spawn specialized agents for parallelized workflows
• Scheduled tasks: Set up background automation for long-running processes
• CLI and SDK: Command-line interface and software development kit for programmatic access
• Managed Agents API: Single API call to spin up agents with persistent state

Powered by Gemini 3.5 Flash

The entire Antigravity ecosystem is optimized for and powered by Gemini 3.5 Flash, Google's newest frontier model for agentic workflows. This combination delivers:

• 4x faster performance than other frontier models
• 72% reduction in token usage compared to Flash 3
• Real-time feedback and artifact viewing
• Seamless integration with Google AI Studio and Android

Key Features

Desktop Application

The standalone Antigravity 2.0 app serves as a central hub for agent interaction, allowing developers to:

• Have synchronous conversations with agents
• View and provide feedback on artifacts in real-time
• Manage multiple agents simultaneously
• Access all project context without IDE constraints

Antigravity CLI

For developers who prefer terminal workflows:

# Create and run an agent
antigravity run --model gemini-3.5-flash "Build a REST API with authentication"

# Manage agent teams
antigravity team create --name "full-stack-dev" --agents 5

Antigravity SDK

Programmatic access for custom integrations:

import { AgentHarness } from '@antigravity/sdk';

const harness = new AgentHarness({
  model: 'gemini-3.5-flash',
  maxAgents: 10
});

await harness.run('Build and deploy a Next.js application');

Integration Ecosystem

Antigravity 2.0 integrates with:

• Google AI Studio: One-click project export/import
• Android Studio: Native Android vibe coding support
• Firebase: Backend integration
• Google Cloud: Enterprise deployment with security controls

Enterprise Features

• Google AI Ultra: $100/month plan with 5x higher usage limits
• Managed Agents: Isolated Linux environments for secure execution
• Cloud Deployment: Agent Platform integration for Google Cloud customers

Case Study: OS Build

Google demonstrated Antigravity 2.0 by building a complete operating system in 12 hours, consuming less than $1,000 in API credits. The autonomous team of agents handled everything from scheduler to memory management.

Availability

Antigravity 2.0 is available today for macOS, Linux, and Windows. The CLI and SDK are immediately accessible, with additional integrations rolling out in the coming weeks.
