Antigravity Boost Mode Benchmark: Free Deep Reasoning vs Commercial Paid Astra

Antigravity Boost Mode Benchmark: Free Deep Reasoning vs Paid Astra

For independent developers, monthly AI coding subscriptions add up rapidly. When proprietary services charge $20 to $200 per seat for "pro" reasoning models, developers legitimately ask: is the paid reasoning upgrade genuinely worth the monthly overhead?

In this lab test, we benchmarked Antigravity's Boost Mode—available at zero additional subscription fee—directly against commercial Astra tiers on identical enterprise tasks.

CONVENTIONAL SINGLE-THREAD AGENT:
Plan ──> Edit ──> Compile Fail ──> Loop (Burns 80k tokens per minor bug)

ANTIGRAVITY BOOST MODE:
Planner Subagent ──> Parallel Code Worker + Linter Validator ──> 1-Pass Verified Commit

The Evaluation Matrix

We created a test suite of 50 challenging software development tasks:

1. Migrating Tailwind v3 configurations to Tailwind v4 post-CSS pipelines.
2. Refactoring Next.js App Router RSC data fetching from waterfalls into parallel Suspense streams.
3. Implementing complex database migration locks in PostgreSQL with rollbacks.

Head-to-Head Benchmark

| Metric | Antigravity Boost Mode | Commercial Astra Tier |

|---|---|---|

| First-Pass Typecheck Pass Rate | 94.0% | 88.0% |

| Average Turns to Resolution | 2.3 turns | 3.8 turns |

| Hallucinated Import Rate | < 1.0% | 4.2% |

| Monthly Subscription Cost | $0.00 | $200.00 |

Why Boost Mode Won Out

• Integrated Subagent Verification: Rather than relying on a single conversational model to remember all constraints, Boost Mode automatically deploys a dedicated validator subagent that executes npm run typecheck and inspects the compiler output before presenting the code diff to the user.
• Architectural Honesty: When a task is ambiguous, Boost Mode halts and requests targeted clarification rather than making catastrophic assumptions in production code.
