Google Antigravity 2.0 goes after Claude Code and OpenAI Codex with a full agent-first rebuild

Key Points:

• Google has removed the IDE from Antigravity, now offering Antigravity 2.0 as a standalone desktop app focused on AI agents rather than a traditional code editor, positioning it against competitors like Claude Code and OpenAI Codex.
• Antigravity 2.0, powered by the Gemini 3.5 Flash model, boasts a processing speed of 289 output tokens per second, significantly outperforming Claude Opus 4.7 and GPT-5.5, and surpassing Google’s previous Gemini 3.1 Pro in coding and agent benchmarks.
• The new agent layer allows the main agent to create and manage subagents asynchronously, supports JSON hooks for behavior customization, scheduled tasks with cron, and introduces new slash commands to enhance user control and interaction.
• Google has expanded the Antigravity ecosystem with a new CLI replacing Gemini CLI, an SDK for custom agent development, deeper integrations with AI Studio, Firebase, and Android, plus a revamped pricing structure including a new $100 AI Ultra tier and discounts for existing users.
• Antigravity 2.0 is available on macOS, Linux, and Windows, with features like live voice transcription and project-based conversations that span multiple folders with permissions, aiming to improve developer workflows and agent usability.
