Antigravity quota: Pro vs Ultra, priced per unit

Google prices Antigravity quota only relatively: Ultra $100 is "5X worth of tokens" versus Pro, Ultra $200 is "20X". Dividing price by multiple is plain first-party arithmetic, and it says something Google's marketing does not: the $100 tier carries zero quota discount.

Ultra $100 buys headroom at Pro's exact rate; only Ultra $200 buys quota at a discount. The $200 tier also adds third-party model access and was cut from $250 in the 2026-05-19 restructure.

Your local price is not these dollars

Google prices per market in local currency, and a regional price is not an FX conversion of the US sticker. An authenticated account view priced in THB (observed 2026-07-22) showed:

FAQ

Is Google AI Ultra $100 better value than Pro for Antigravity?
Not per unit of quota. $100 buys 5X of Pro's quota, which is exactly $20.00 per quota unit, the same rate Pro charges. Ultra $100 buys headroom, not a discount.
Which Antigravity plan has the cheapest quota?
Ultra $200: 20X of Pro quota works out to $10.00 per quota unit, half of Pro's $20.00. It is also the only tier with third-party model access.
How much Antigravity quota does each plan include, in absolute numbers?
Google does not publish absolute quota for any tier, only the relative 5X and 20X multipliers and qualitative words. Absolute numbers exist only as community measurements.
