Google AI Pro vs Google AI Ultra 5x
Google AI Pro is for fast, capable work at $20, plus Gemini everywhere else; Google AI Ultra 5x is for Antigravity users emptying the AI Pro window. Google AI Ultra 5x costs $80/mo, 4x Google AI Pro's $20/mo.
Our verdict
Same Google product on both sides. Between these rungs the price and the allowance change; the agent does not.
The Google ladder. It splits at $20. Below that, AI Plus is Gemini in the chat apps and no coding agent worth the name. From AI Pro up, every rung runs the same Antigravity CLI with the same models; Ultra buys volume, not capability.

We have not measured Google AI Ultra 5x on its own plan; its card below points at the closest graded evidence.
The most improved plan we track, and fast-and-cheap now belongs to it outright. Gemini 3.7 Flash is quick and genuinely good on the work we give it, prompted apps included. The gripe is the Antigravity harness itself: rough-looking, and looser with your instructions than the better harnesses.
Pros
- 3.7 Flash owns the fast-and-cheap lane: quick and actually good
- A real coding agent at $20
- Gemini in Docs, Gmail and the chat app thrown in
Cons
- About eight real-world runs empty the weekly window
- The Antigravity harness looks rough and is loose with instructions
Best for Fast, capable work at $20, plus Gemini everywhere else.
How far it goes: about 9 to 10 times a week
Our whole Real-world issues suite runs about 9 to 10 times a week on this plan, depending on which model you run.
That works out at about 39c to 52c of the subscription per run, at the list price.
Measured on this plan, at 8.5% to 11.3%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
AI Pro's one real fault is the window: at about 13% of it per real-world run, eight runs a week is the budget. Ultra 5x exists to fix exactly that, and now that 3.7 Flash is worth running in volume, paying $80 for more of it is no longer a strange idea.
Pros
- Fixes the one thing wrong with AI Pro: the weekly window
- More of a model now worth running in volume
Cons
- Same Antigravity weaknesses at four times the price
- Chat users gain nothing over AI Pro
Best for Antigravity users emptying the AI Pro window.
How far it goes: we have not measured this plan
Same Antigravity CLI as AI Pro with a bigger allowance - the AI Pro scorecards are the closest evidence.
