Plan guide

How much coding do you get from Google AI Ultra $100 (Antigravity)?

Available models: Sonnet 4.6 / Opus 4.6 / Gemini 3.8 Flash — Free individual access shown. Models restricted to paid plans or private previews are excluded.. $100/mo buys about 25 h/week of building at p50 peak (p10–p90 10–50) — hours are guessed, so treat them as a guess. Not measured: this plan has no verified agent/model evaluation in the current suite, so it is excluded from the stack builder's ranking. Catalog note: Google AI Ultra at $100 is officially 5x the AI Pro limits in Antigravity. Hours scaled 2.5x the Pro seat, not the banner 5x. The bundle also buys storage/YouTube Premium — only coding hours counted here. Guessed.
