Google Antigravity 2.0

Overview

Antigravity 2.0 is a major expansion of Google's agent-first development platform, announced at Google I/O 2026 on May 19, 2026 — six months after the original Antigravity 1.0 launched as a single VS Code-fork IDE alongside Gemini 3 (November 2025). Where 1.0 was one desktop app, 2.0 is a five-surface platform: standalone desktop (with the Editor still built on the VS Code codebase), Go-based Antigravity CLI (replacing the previous Gemini CLI), an SDK, Managed Agents in the Gemini API / Interactions API, and Google Cloud / Gemini Enterprise deployment paths.

Underneath, the model also changes: Antigravity 2 ships with Gemini 3.5 Flash as the default agentic model, replacing Antigravity 1.0's Gemini 3 Pro default. The 2.0 push is explicitly about putting multi-agent orchestration front and center — dynamic subagents, scheduled background tasks, voice command input, and native integrations with Google AI Studio, Firebase, and Android.

What's New

Five-surface platform replaces single IDE

Antigravity 1.0 was a desktop IDE only. Antigravity 2 ships as:

• Desktop app — Refreshed, multi-agent-oriented standalone desktop client.
• Antigravity CLI — A new Go-based CLI, faster and more responsive than the predecessor Gemini CLI, suitable for headless and CI workflows.
• SDK — Programmatic access to the same agent harness powering Google's products; lets you define custom agent behaviors and host them on your own infrastructure.
• Managed Agents (Gemini API) — A preview managed tier in the Gemini API / Interactions API for spinning up Antigravity agents in isolated Linux environments without operating the harness yourself.
• Gemini Enterprise / Google Cloud — Enterprise deployment paths for the same agent runtime, sitting alongside the broader Gemini Enterprise / Google Cloud lineup.

Multi-agent orchestration as the default

Antigravity 2.0's flagship change is putting multi-agent orchestration in the foreground rather than treating it as an Editor + Manager split (as 1.0 did). Developers can orchestrate multiple local agents, use subagents / hooks / asynchronous task management, and schedule background work that runs without a developer sitting at the desk. Note: Google frames the newer subagent teamwork capability as an early research preview — validate behavior before treating it as production-ready.

Antigravity CLI replaces Gemini CLI

The previous Gemini CLI is being transitioned to Antigravity CLI, rebuilt in Go for higher throughput. Antigravity CLI is not a 1:1 drop-in replacement — the binary, command surface, and config layout change, and migration touches scripts, skills, hooks, subagents, extensions/plugins, and output assumptions. Google has announced that Gemini CLI will stop serving requests for individual free / Pro / Ultra users on June 18, 2026, while enterprise access remains unchanged for now — so personal users need to plan migration on that timeline.

Live voice transcription

The desktop app adds live voice transcription for prompting agents and leaving feedback using natural speech, rather than typing every instruction. This is transcription, not full voice-command automation — the model still receives text prompts assembled from your speech.

Google developer-tooling integrations

Antigravity 2.0 ships with integrations across Google developer tooling, including Google AI Studio export to Antigravity and Build with Google plugin bundles that expose Firebase-related workflows inside the platform. Confirm in the official docs which specific Android / Firebase touchpoints are first-class native features versus plugin-mediated workflows before depending on them.

Default model is now Gemini 3.5 Flash

Antigravity 1.0 defaulted to Gemini 3 Pro. Antigravity 2 defaults to the newer Gemini 3.5 Flash, which Google says is faster and stronger on coding / agentic benchmarks. 1.0's multi-model support (Claude Sonnet 4.5, GPT-OSS, etc.) carries over.

Performance Benchmarks

Antigravity 2 itself does not publish a unit benchmark — it's a platform, not a model. The agentic performance comes from the default model:

Google states Gemini 3.5 Flash outperforms Gemini 3.1 Pro on these coding and agentic benchmarks. Per-task results in Antigravity 2 will vary based on which model you select (1.0's multi-model support, including Claude Sonnet 4.5, persists).

Migration Guide

From Antigravity 1.0

Antigravity 2 is described by Google as a full rebuild, not an incremental update. Practical advice:

• Reinstall the desktop app — The 2.0 desktop client is a refreshed binary; expect to re-authenticate and reconnect your project workspaces rather than auto-upgrade.
• Move from Editor/Manager split to multi-agent orchestration — Workflows that lived in 1.0's two-pane UI may need to be redesigned around dynamic subagents and scheduled tasks.
• Update default model expectations — The default flips from Gemini 3 Pro to Gemini 3.5 Flash. Re-run any internal evals that previously baselined on 3 Pro to confirm 3.5 Flash performs at least as well on your task mix.

From Gemini CLI (deadline: June 18, 2026)

Google has announced the transition from Gemini CLI to Antigravity CLI, with Gemini CLI ceasing to serve individual free / Pro / Ultra users on June 18, 2026. Enterprise access remains unchanged for now. Practical migration:

• The new CLI is written in Go and is not a 1:1 drop-in for Gemini CLI. Migration touches scripts, skills, hooks, subagents, extensions/plugins, and output assumptions.
• Test scripts and CI jobs that depend on Gemini CLI against Antigravity CLI before flipping production pipelines.
• Plan the migration window before June 18, 2026 if you are on a free, Pro, or Ultra tier.

API and channel access

Antigravity 2.0's Managed Agents tier is accessible in preview through the Gemini API / Interactions API. The SDK provides programmatic access to the agent runtime — model, API, and infrastructure costs may still apply depending on how you deploy. Enterprise deployment goes through Google Cloud / Gemini Enterprise. The desktop app still offers a free tier, but usage is quota-limited and higher limits are tied to Google AI Pro / Ultra plans — this is a meaningful change from 1.0's open public preview.

Pricing & Plans

Antigravity 2.0 changes the pricing posture from 1.0's open public preview. The desktop app still offers a free entry point, but higher usage is quota-tied to Google AI Pro / Ultra plans, and Managed Agents are rolling out in preview through the Gemini API / Interactions API.

Specific Managed Agents per-call pricing should be verified against the current Gemini API / Interactions API pricing page before committing production budgets.

Best For

• Teams already on Antigravity 1.0 who hit the limits of a single Editor/Manager IDE and need parallel subagents or scheduled background runs.
• Developers running headless / CI agentic workflows who can adopt the new Go-based Antigravity CLI in place of Gemini CLI.
• Builders who want to embed Google's agent harness in their own infrastructure via the SDK rather than running the desktop app.
• Product teams that need a managed agent runtime (Managed Agents in Gemini API) without operating the harness themselves.
• Enterprises on Gemini Enterprise that want a unified agent deployment surface alongside their existing Google Cloud / Workspace footprint.
• Teams currently using API-based coding agents like Claude Code who want to evaluate a Google-native agent harness with the same multi-model flexibility.
