Antigravity Agent PreviewManaged Agents (Gemini API)
Antigravity Agent Preview

Gemini API managed general agent in isolated sandbox—inference at standard Gemini rates, default Gemini 3.5 Flash $1.50/$9 per MTok, sandbox free in preview.

Managed Agents (Gemini API)

Gemini API cloud-persistent agents—same billing as Antigravity Agent; for SDK / Interactions API programmatic calls and long IDE-less tasks.

Plan details

Antigravity Agent

Gemini API agentRecommended
Input
$1.50
Output
$9
Official
Usage
Antigravity Agent Preview is a general-purpose managed agent on Gemini API—autonomous planning, reasoning, code execution, file management, and web browsing in an isolated Linux sandbox; all inference at standard Gemini list rates.
Models
Agentic-loop intermediate input/reasoning tokens bill too; tool fees (Grounding, code execution, etc.) per ai.google.dev Tools section. Preview-period CPU/memory/sandbox execution is free.
Highlights
Callable via Gemini API Interactions API or Antigravity SDK—independent of IDE subscription quota, suited to CI/CD, background automation, and long tasks without an IDE window.
Best for
Automation and backend integrations needing programmatic Antigravity agents

Managed Agents (Gemini API)

Cloud-persistent agents
Input
$1.50
Output
$9
Official
Usage
Managed agents in Gemini API share Antigravity Agent billing—model inference at Gemini list rates, environment compute free in preview—for cloud-persistent agent tasks independent of a local IDE.
Models
Separate from in-IDE conversational agents (Google AI Pro/Ultra baseline quota)—Managed Agents bill directly via Gemini API / AI Studio or Enterprise consumption rates.
Highlights
Estimate token consumption by target Gemini model before integration—complex multi-agent tasks (e.g. /teamwork-preview) can burn quota quickly; official guidance recommends reserving AI credits.
Best for
CI/CD, cloud long-running tasks, and IDE-less agent automation

AI Credits Overage

Subscription overage
Input
Enterprise consumption rates
Output
After Pro/Ultra baseline quota · docs/plans
Official
Usage
Google AI Pro/Ultra subscribers can buy AI credits after exhausting Antigravity baseline quota—billed at Gemini Enterprise Agent Platform consumption pricing (antigravity.google/docs/plans).
Models
AI Credit Overages setting: Never (wait for 5-hour/weekly refresh) or Always (auto-deduct credits, revert to baseline after refresh). Per-model baseline usage visible in settings.
Highlights
After I/O 2026, AI credits are overage-only—not bundled in base Google AI plans; underlying billing still maps to Gemini model token rates—see gemini-token-api for per-model prices.
Best for
Pro/Ultra users needing overage beyond baseline quota

Gemini Enterprise (Organization)

Consumption-based
Output
Gemini Enterprise Agent Platform · GCP ToS
Official
Usage
Organization plans access Antigravity 2.0 and CLI via Google Cloud (antigravity.google/pricing)—Google Cloud project integration, consumption-based API pricing, under GCP Terms of Service.
Models
For enterprises needing team contracts, compliance, and unified GCP billing—pricing may differ slightly from ai.google.dev consumer API; see cloud.google.com Gemini Enterprise pricing.
Highlights
docs/plans states BYOK is not supported outside organizational GCP tiers—contact Google Cloud sales or your account manager for enterprise evaluation.
Best for
Teams and orgs needing GCP integration and Enterprise compliance

Notes

  • Antigravity's default agent model is Gemini 3.5 Flash—reference API inference $1.50 input / $9 output per MTok (Paid Standard); actual cost depends on runtime Gemini model and agentic loop length.
  • Organization plans access Antigravity 2.0 and CLI via Google Cloud Gemini Enterprise Agent Platform with consumption-based API pricing under GCP Terms of Service (antigravity.google/pricing).
  • BYOK or custom endpoints for extra limits are not supported (docs/plans)—overage requires AI credits or waiting for quota refresh.
