Google Antigravity 2.0: A Complete Overhaul After I/O 2026
Google Is No Longer Sitting on the Sidelines
Google I/O 2026 on May 19 marked Google's biggest move in the AI coding tool race. Antigravity 2.0 — a comprehensive upgrade — officially launched with Gemini 3.5 Flash as the default model, multi-agent orchestration, and a significant AI Ultra price cut.
While Cursor leads in IDE experience, Claude Code dominates the terminal-native segment, and OpenAI Codex focuses on cloud agents — Google chose a different approach: a multi-agent, multi-interface platform.
Notable Changes
Gemini 3.5 Flash: 4x Faster
Gemini 3.5 Flash reaches ~290 output tokens per second — roughly 4x faster than Opus 4.7 or GPT-5.5, according to Artificial Analysis data. This is Antigravity 2.0's new default model, replacing Gemini 3.0.
Speed matters beyond smooth UX. In agent environments, AI calls dozens of tools in sequence, each taking hundreds of milliseconds. Cumulative speed becomes a significant time saver for entire workflows.
However, an honest assessment: Gemini 3.5 Flash scores 45.0 on the Artificial Analysis Coding Index, below Gemini 3.1 Pro (56.5) per BetterStack. This model prioritizes speed over reasoning depth — a clear trade-off for complex coding tasks.
Multi-Agent Orchestration
Antigravity 2.0 introduces dynamic subagents. Each subagent specializes in a specific task: writing code, running tests, reviewing, debugging. When needed, subagents hand off work to each other without developer intervention.
Cursor is pursuing a similar direction with Build in Parallel. But Google has a unique advantage: owning both model and infrastructure, enabling deeper optimization at the inference layer.
Antigravity CLI: A New Interface
Google rebuilt the CLI in Go, replacing Gemini CLI for individual users (scheduled to sunset on June 18). The new CLI comes with a public SDK, allowing developers to integrate Antigravity into custom workflows.
This is a smart move. Many developers don't want IDE lock-in — they want AI running directly in the terminal, integrated into CI/CD pipelines or custom automation.
Scheduled Background Tasks
This feature lets agents run on a schedule. Example: Friday evening runs a full codebase refactoring, Saturday morning runs a security audit. No babysitting required.
Pricing: The Price War Is Heating Up
Google overhauled its entire AI subscription tier:
- AI Plus: $7.99/month (basic)
- AI Pro: $19.99/month (unchanged)
- AI Ultra Entry: $99.99/month (new, 5x Pro limits)
- AI Ultra Top: $200/month (down from $249.99)
Notably, Google shifted from daily prompt caps to a compute pool — computing resources refresh every 5 hours with a weekly cap, plus paid top-up credits.
Comparison with competitors:
| Tool | Individual Plan | Top Tier |
|---|---|---|
| Antigravity 2.0 | $19.99/mo | $200/mo |
| Cursor | $20/mo | $200/mo |
| Claude Code | $17-20/mo | $200/mo |
| OpenAI Codex | $20/mo | $200/mo |
| Kiro | $20/mo | $200/mo |
Top-tier pricing has converged at $200/month. Competition now revolves around value per dollar, not lower prices.
How Does Antigravity Compare to Competitors?
Antigravity vs Cursor
Cursor excels in IDE experience — Composer 2.5 now matches Opus 4.7 and GPT-5.5 on benchmarks, with cheaper input/output pricing. Cursor also shipped Build in Parallel and Microsoft Teams integration.
Antigravity 2.0 is stronger in multi-agent orchestration and CLI. Google owning its own model enables deeper latency optimization.
Antigravity vs Claude Code
Claude Code is a terminal-native tool, ideal for developers who prefer working in the terminal. Anthropic recently doubled the 5-hour limits for Pro, Max, Team, and Enterprise.
Antigravity has a multi-interface advantage: desktop app, CLI, public SDK. But Claude Code still leads on coding benchmarks — Opus 4.7 scores 64.3% on SWE-Bench Pro, ahead of GPT-5.5's 58.6%.
Antigravity vs OpenAI Codex
Codex currently has 4 million weekly users. OpenAI recently launched a Codex desktop app for both macOS and Windows, switching to API token billing.
Google has a cloud infrastructure advantage — Antigravity integrates directly into the Google Cloud ecosystem. But OpenAI has a new AWS Bedrock partnership, allowing GPT-5.5 usage through the same AWS account.
Personal Take: Who Should Choose Antigravity 2.0?
Antigravity 2.0 fits best for:
- Developers already on Google Cloud — native integration, single billing account
- Teams wanting multi-agent workflows — subagent orchestration is a unique strength
- Terminal-first developers — new Go-based CLI with a public SDK
If already comfortable with VS Code or JetBrains, Cursor remains the more natural choice. If pure terminal work is the priority, Claude Code is hard to beat.
The most noteworthy aspect is the pricing strategy. Google cut AI Ultra from $249.99 to $200/month and added a $99.99 entry tier — signaling a push to attract mid-range developers. This directly competes with Cursor Ultra and Claude Max.
The Bigger Picture: The Race Is Entering a New Phase
Looking broadly, AI coding tools are shifting from "one tool, one model" to "multi-agent, multi-interface". Each major company is building its own platform:
- Google: Multi-agent orchestration + Gemini ecosystem
- Anthropic: Terminal-native + coding-first model
- OpenAI: Cloud agent + desktop app
- Cursor: IDE-first + parallel execution
According to RAND, 80-90% of products labeled "AI agent" today are still chatbot wrappers. The seven tools in this comparison are the real deal — capable of planning, executing, and verifying code autonomously.
Developers don't need to pick just one tool. The current trend is using multiple tools for different tasks — Claude Code for terminal, Cursor for IDE, Antigravity for background automation.
