🚀 Google Antigravity 2.0 Highlights

  • Agent-first design: Antigravity 2.0 is no longer an IDE add-on; it’s a standalone desktop app built around autonomous agents.
  • Performance leap: Runs on Gemini 3.5 Flash, delivering 289 tokens/sec, far faster than Claude Opus (67) and GPT‑5.5 (71).
  • Benchmarks: Outperforms Google’s own Gemini 3.1 Pro on coding and agentic tasks.

🧩 New Agent Capabilities

  • Agents can spawn subagents, run tasks in parallel, and keep contexts uncluttered.
  • Asynchronous execution prevents stalls during compilation.
  • JSON hooks allow customization without wrappers.
  • Scheduled Tasks layer adds cron-like automation.
  • Slash commands like /goal, /grill-me, and /browser define workflows.
  • Voice input now transcribes live, and projects span multiple repos with permissions.

⚙️ Developer Tools & Ecosystem

  • New CLI replaces Gemini CLI, requiring workflow migration.
  • SDK enables custom agent development.
  • Deeper integration with AI Studio, Firebase, and Android, plus a dedicated Android app.

💰 Pricing Updates

  • New $100 AI Ultra tier between Pro ($20) and flagship Ultra.
  • Flagship Ultra price cut from $250 → $200, with 20× Pro limits.
  • Bonus credits ($100) for Ultra subscribers until May 25.
  • Existing IDE users will automatically roll over to 2.0.

🎤 Demo Showcase

  • Agents built an operating system from scratch for under $1,000 in tokens.
  • They even coded a Doom clone to demonstrate capabilities.

In short, Google is positioning Antigravity 2.0 as a direct competitor to Claude Code and OpenAI Codex, emphasizing speed, agent autonomy, and developer ecosystem integration.
