Question 1

Copilot Max vs Google AI Ultra $100 (Antigravity) for coding: which gives more building hours per dollar?

Accepted Answer

At p50 peak, Copilot Max returns 0.22 building h/week per $/month (22 h/week for $100/mo) and Google AI Ultra $100 (Antigravity) returns 0.25 building h/week per $/month (25 h/week for $100/mo), so Google AI Ultra $100 (Antigravity) gives more building hours per dollar; neither runs a benchmark-measured model for building; Copilot Max hours are guessed — treat them as a guess; Google AI Ultra $100 (Antigravity) hours are guessed — treat them as a guess.

Question 2

What do Copilot Max and Google AI Ultra $100 (Antigravity) cost?

Accepted Answer

$100/mo and $100/mo. Comparisons only pair plans within 1.5× of each other on price.

Question 3

Can Copilot Max and Google AI Ultra $100 (Antigravity) run as terminal CLI agents?

Accepted Answer

Copilot Max runs as a CLI agent. Google AI Ultra $100 (Antigravity) runs as a CLI agent. The stack builder can require at least one CLI seat.
