Google AI Ultra 20×: $199.99/month

Google AI Ultra 20× covers about 11k turns of balanced coding work a month, 56 per dollar. That is the 2nd most of the 37 plans with a usage figure. No plan at $199.99 or less covers more.

What it includes

Price	$199.99/month
Coding agent	Antigravity
Limit, as Google words it	20× the tokens of Pro, refreshed every five hours until a weekly limit.
Usage at API prices	$10k–$11k a month, 52–54× the price
Evidence	Anecdotal · checked Nov 12, 2026
Strongest model	Gemini 4 Carbon, 60.0 on the Intelligence Index

Models

Gemini 3.8 Flash · up to 30.8
Gemini 4 Hydrogen · up to 53.9 · Rolled out 12 Nov 2026; its quota rate is unknown, between Flash’s and Argon’s
Gemini 4 Carbon · up to 60.0 · Charged at about 3× its API price against the pool (one user report)
Gemini 4 Argon · up to 50.4 · Charged at about 3× its API price against the pool (one user report)
Claude Opus 5.5 · up to 59.1
Claude Sonnet 5.5 · up to 54.5

Value by kind of work

Turns of mixed coding work the allowance covers in a month, each kind on the plan’s cheapest model that is good enough. How this is worked out.

Work mix	Turns a month	Per dollar
Light only (100% light)	36k–37k	181–187
Mostly light (40% normal, 60% light)	17k–33k	83–167
Balanced (5% frontier, 15% hard, 60% normal, 20% light)	6.1k–21k	31–103
Mostly hard (10% frontier, 40% hard, 40% normal, 10% light)	3.9k–15k	19–74

On the balanced mix: frontier work on Gemini 4 Carbon (high reasoning), counting 29% of a turn; hard work on Gemini 4 Carbon (medium reasoning); normal work on Gemini 4 Hydrogen (high reasoning); light work on Gemini 3.8 Flash (medium reasoning).

How the figure was obtained

The measured Pro pool (Real API Pricing, $119–123 a week) times Google's official 20×. Gemini 3.8 Flash draws on it at API prices. Carbon and Argon use it up about three times as fast as their API price implies, according to one secondhand user report, so they are valued at a third of the pool, shown from half to double that. Hydrogen is a day old and its rate is unknown; its range runs from Argon’s rate to Flash’s. Claude models in Antigravity have their own unpublished limit and are not valued.
