Google Antigravity pricing & limits

How Google Antigravity usage limits work

Antigravity has no standalone subscription. Paid quota comes with a Google AI plan: Pro, Ultra 5x or Ultra 20x. The free tier includes Gemini 3.8 Flash, unlimited Tab completions and all product features, such as scheduled tasks and the CLI.

Google says the limits track the amount of work the agent does, not the number of prompts, so complex tasks use more quota. Gemini models share one pool, drawn down by API price; non-Gemini models have a separate fixed limit. Google publishes no absolute quota numbers.

Ultra 5x ($100) gives 5x the Pro token allowance and Ultra 20x ($200) gives 20x, per Google's May 19, 2026 plans post.

When limits reset

Free: quota refreshes weekly. Google AI Pro and Ultra: refreshed every five hours until the weekly limit is reached.

What happens when you hit the limit

On Pro or Ultra, purchased AI credits can cover overage. The AI Credit Overages setting is either Never (wait for the quota to refresh) or Always (use credits, then switch back when the quota refreshes). On the free tier you wait for the weekly refresh.

How to check your usage
