Google AI Ultra 5x costs $100/mo; Kimi Allegro costs $99/mo. More usage is expected from the more expensive plan; the question is whether it buys anything else.

Our verdict
Choose Google AI Ultra 5x. Antigravity is rough, but the Google bundle has value outside the agent.
Kimi Allegro costs about the same and its credits still run out too fast. Its design ability does not make up the difference.
$100 buys more Gemini usage and a larger Google bundle. It does not improve Antigravity or the available models. Start with the $20 AI Pro plan and upgrade only if its usage limit blocks your work.
Pros
More Gemini usage
A larger Google services bundle
Cons
The same rough Antigravity agent
The same models as the $20 plan
Best for Google AI Pro users blocked by its usage limit.
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.
$99 gives K3 five times the agent credits of Allegretto. The usage limit still runs out too quickly. K3 has regressed in our use since release. More credits do not make it worth buying.
Pros
Five times the Allegretto agent credits
Good visual design
Cons
The usage limit drains too quickly
K3 has regressed since release
Best for Nobody.
