Google launches Antigravity 2.0 with desktop app, Go-based CLI, and SDK at $100/month
Google announced Antigravity 2.0 at I/O 2026, transforming its coding tool into a full developer platform with a revamped desktop app supporting multi-agent orchestration, a new Go-based CLI, and an SDK for custom agents. The company introduced a $100/month AI Ultra tier and confirmed Gemini CLI will shut down for consumers on June 18, 2026.
Google launches Antigravity 2.0 with desktop app, Go-based CLI, and SDK at $100/month
Google announced Antigravity 2.0 at I/O 2026 on Monday, expanding its agentic coding tool into a full developer platform with a revamped desktop app, a new command-line interface built in Go, and an SDK for building custom agents.
Desktop app gains multi-agent orchestration
The updated desktop application introduces multi-agent orchestration as its core feature. Developers can now run multiple agents simultaneously on different problems, design custom subagent workflows, and schedule background tasks that execute automatically.
Antigravity 2.0 integrates natively with Google AI Studio, Firebase, and Android. Developers can export projects from AI Studio directly to their local Antigravity instance while preserving full context.
New Go-based CLI replaces Gemini CLI
Google is shipping a new Antigravity CLI built in Go, which the company claims is faster and more responsive than its predecessor.
The older Gemini CLI will shut down for consumers on June 18, 2026. Consumer access to Gemini CLI and Gemini Code Assist IDE extensions will cease for AI Pro, AI Ultra, and free-tier users on that date. Enterprise customers with Gemini Code Assist Standard or Enterprise licenses will retain access.
SDK enables custom agent development
The Antigravity SDK provides developers with tools to create custom agents on top of Google's coding infrastructure. Google Cloud customers can connect directly to Antigravity, and custom agent templates are available in AI Studio for enterprise use cases.
According to Google, the company used Antigravity internally to build consumer features, including custom UI generation in Google Search.
Powered by Gemini 3.5 Flash
Antigravity 2.0 runs on the new Gemini 3.5 Flash model, which Google claims outperforms Gemini 3.1 Pro on coding and agentic benchmarks while running four times faster than competing frontier models. Google says Gemini 3.5 Flash was co-developed using Antigravity.
The desktop app now supports native voice commands, allowing developers to control agents through speech rather than typing.
Pricing restructure targets developer market
Google introduced a new AI Ultra tier at $100 per month with five times the usage limits of the AI Pro plan. The existing top-tier AI Ultra subscription drops from $250 to $200 per month, offering 20 times the Pro limits.
The $100 price point directly competes with OpenAI's ChatGPT Pro tier and Anthropic's Claude Max, both priced at $100 per month. The $200 premium tier matches Anthropic's top Claude Max plan.
What this means
Google is consolidating its developer tools around Antigravity while sunsetting Gemini CLI, signaling a strategic shift toward multi-agent orchestration as the primary interaction model for AI-assisted development. The $100/month pricing puts Google in direct competition with OpenAI and Anthropic at a moment when GitHub has paused new Copilot sign-ups due to agentic workload economics. The SDK release is particularly significant—it positions Antigravity not just as a tool but as a platform for building custom coding agents, potentially creating a developer ecosystem around Google's infrastructure.
