Google AI Ultra 5x vs SuperGrok Plus
Google AI Ultra 5x is for Antigravity users emptying the AI Pro window; SuperGrok Plus is for people who want Grok plus live X search in one subscription. SuperGrok Plus costs $100/mo, 1.3x Google AI Ultra 5x's $80/mo.
Our verdict
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.
The xAI ladder. It splits at $30. Lite, below that, is chat only; from SuperGrok up every rung runs the same Grok CLI and model. xAI publishes no usage multiples, so we cannot say what a bigger rung buys beyond "more". The one feature only this ladder sells is live X search, and only SuperGrok Plus has it.

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

The one thing on this page you cannot buy anywhere else is X: live search over posts is part of the plan, and if your work runs on what people are saying right now, that alone can justify the $100. As a coding subscription it inherits Grok 4.6 and its speed problem.
Pros
- Live X search, which no other plan here has
- Higher limits than the $30 tier
- The same Grok CLI as the $30 tier
Cons
- xAI states no usage multiple, so the extra $70 is unquantified
- The coding agent is the slow 4.6
Best for People who want Grok plus live X search in one subscription.
