Antigravity Context Window Limits Test

Can it eat a whole monolith? Formatting the limits of the context window.

The Benchmark

"Context Window" is a buzzword. Everyone claims 100k, 200k, 1M. But how usable is that context? Does the model get confused?

We put Antigravity (Gemini 3) to the test against the "Needle In A Haystack" benchmark.

The Test Setup

We created a dummy repository containing 500 files. Each file contains randomly generated TypeScript code. In one file (src/utils/hidden/secret.ts), we defined a variable: const THE_SECRET_KEY = "antigravity_is_awesome_2025";.

We then loaded the entire folder into Antigravity and asked: "What is the secret key?"

The Results

  • GPT-4o (128k context): FAILED. It couldn't ingest all 500 files. We had to manually cherry-pick folders.
  • Claude 3 Opus (200k context): PASSED, but took 45 seconds to process.
  • Gemini 3 Pro (2M context): PASSED in 2.4 seconds.

Implications

This means you don't need to micro-manage your AI context anymore. You can just dump your whole repo into the chat and trust that it sees everything. This is a massive workflow improvement for legacy codebases where documentation is scarce.

About Google Antigravity IDE

Google Antigravity is the next-generation AI-first Integrated Development Environment (IDE) powered by Gemini 3. Unlike traditional editors that merely autocomplete code, Antigravity features autonomous agents that can plan, write, debug, and test complex software systems.

Designed for the post-Copilot era, it features a 2 Million Token Context Window, allowing it to understand your entire codebase, documentation, and dependencies in real-time.Download the Preview →

Frequent Questions

  • Is Antigravity free?Yes, the Public Preview is free to use. A Pro tier with higher rate limits will be available later.
  • Does it support VS Code extensions?Absolutely. Antigravity handles 99% of VS Code extensions natively via the OpenVSX registry.
  • How does it compare to Cursor?Antigravity offers a significantly larger context window (2M vs 200k) and deeper agentic capabilities for autonomous tasks.
