What happened during the keynote
While the mainstream press focused on the Samsung glasses and Gemini Spark, Google quietly launched the most aggressive technical offensive of its keynote: Antigravity 2.0. Varun Mohan (Director of Software Engineering at Google) and Logan Kilpatrick (Google DeepMind) took to the stage to reveal a product that has almost nothing to do with Antigravity 1.0, released in November 2025.
The moment that silenced the room: Mohan asked Antigravity 2.0 to code a complete operating system kernel in parallel, then ran a clone of Doom directly on that freshly created OS. Total cost in tokens consumed: under 1,000 dollars. The audience, made up mostly of developers, probably understood at that moment that the bar had just moved.
As we documented in our full article on Google I/O 2026, this announcement is part of a broader strategy. But Antigravity 2.0 deserves its own treatment, because it directly targets two of the biggest successes in the current AI ecosystem: Anthropic's Claude Code and Cursor.
From standalone editor to complete platform
Antigravity 1.0, launched in November 2025, was a code editor powered by Gemini. Not revolutionary in itself. But above all, as we analysed in our article on the AI startups that outperform, Cursor (built on the same AI-first editor principle) exploded to reach nearly 1 billion in annualised revenue in 2.5 years. Anthropic, for its part, made Claude Code one of its most dynamic sources of enterprise revenue.
Antigravity 2.0 responds to this competition by changing product category entirely. It is no longer an editor. It is a platform with 5 surfaces, all connected to the same "harness" (the underlying agent engine):
- Antigravity 2.0 Desktop: a standalone application (macOS, Linux, Windows) that is no longer an IDE but an agent orchestrator. You talk to it in natural language or by voice command, and several agents work in parallel on your request.
- Antigravity CLI: a command-line tool that replaces the old Gemini CLI. Recoded in Go for speed. You launch agentic workflows directly from your terminal.
- Antigravity SDK: for hosting Antigravity agents on your own infrastructure. Useful for companies that want to keep their code in-house.
- Managed Agents in the Gemini API: you call an agentic workflow as simply as you call a chat completion. Google provides the isolated Linux environment.
- Gemini Enterprise Agent Platform: the enterprise variant, with governance, audit and compliance.
Google's strategic insight here matters: the future of AI programming is not a single editor, but a constellation of interconnected tools. The developer will move fluidly between desktop, terminal, mobile and API depending on context. All these surfaces share the same agent engine, so improvements benefit the whole ecosystem at once. That is probably the right read of the market, and it is what has the competition worried.
The engine under the bonnet: Gemini 3.5 Flash everywhere
The entire Antigravity ecosystem runs by default on Gemini 3.5 Flash, the new model we broke down in our Gemini Flash vs GPT-5.5 vs Opus 4.7 comparison. That choice is no accident.
As a reminder, Gemini 3.5 Flash beats its predecessor 3.1 Pro on coding and agentic benchmarks, at 1.50 dollars per million input tokens. Its speed of 289 tokens per second, four times faster than Opus 4.7 and GPT-5.5, becomes critical when running several agents in parallel. Latency compounds: if each agent waits 10 seconds to start, and you launch 5 in parallel, you lose 50 seconds on Claude Opus. On Gemini 3.5 Flash, you lose 12 seconds. On a workflow that runs for several hours, the gain becomes massive.
Gemini 3.5 Flash's score on MCP Atlas (83.6%) and Toolathlon, the multi-tool orchestration benchmarks, is also the highest in the industry. That is exactly the kind of task Antigravity 2.0 runs all day long.
The demo that stuck in people's minds
Let's go back to the highlight of the presentation. Varun Mohan launched an Antigravity 2.0 workflow with a simple request: "Build an OS kernel and run a clone of Doom on it."
Several agents got to work in parallel. While the conference carried on, the screen showed:
- One agent working on the kernel's memory architecture
- Another handling the input and output drivers
- A third coding the file system
- A fourth compiling the whole thing
- A fifth writing the Doom clone in C
After a few minutes, the system was functional. Mohan launched Doom on this kernel created live, and the game ran. The total cost: under 1,000 dollars in tokens consumed.
This demo is spectacular, but it is a keynote demo. As we documented in our article on faked AI demos, this kind of presentation may involve cherry-picking or advance preparation. The real question is: what happens when an ordinary developer tries to reproduce it from home? The first user feedback will appear in the coming weeks. Worth watching closely before concluding anything.
The concrete new features of the Desktop App
The centre of gravity of Antigravity 2.0 is the desktop application. Here is what it brings in practice.
Dynamic parallel agents. You launch a complex task, and Antigravity automatically breaks the work down into sub-agents that work in parallel. No manual configuration: the system decides how many sub-agents to launch and how to distribute the work.
Scheduled background tasks. You can schedule agents to work overnight (refactoring code, writing tests, updating dependencies). You find the work done in the morning.
Voice commands. You talk to Antigravity as you would to Spark. "Create me a REST API in Python that handles JWT authentication and an endpoint for user profiles." The agent understands, codes, tests, delivers.
Multi-repository projects. A real difference from Claude Code and Cursor: an Antigravity project can cover several Git repositories simultaneously. If your application has a React frontend, a Python backend and a mobile service in Swift, Antigravity handles all three consistently.
Grouped conversations. Your exchanges with the agents are organised by project, with persistent memory. You pick up where you left off last week.
The new pricing: Google plays the price war
Google has also announced a pricing overhaul that confirms its aggressive intent. Here is the new grid:
| Plan | Antigravity (Google) | Claude Code Max (Anthropic) | Codex Pro (OpenAI) |
|---|---|---|---|
| Top tier | $200/month (Ultra) | $200/month | $100/month |
| Limits compared with the Pro plan | 20x Pro | 5-20x Pro depending on the period | Variable |
| Flagship model used | Gemini 3.5 Flash (and 3.5 Pro soon) | Claude Opus 4.7 | GPT-5.5 |
