Claude Max 5x vs Google AI Ultra 5x
Claude Max 5x is our pick of the heavy band. Claude Max 5x costs $100/mo, 1.3x Google AI Ultra 5x's $80/mo.
Our verdict
The Anthropic ladder. Every Claude plan is Claude Code on the same 5-hour rolling window, and a bigger rung buys a bigger allowance. The exception is Fable, which ships only on the Max tiers, so $20 buys Opus 5 and Sonnet 5 rather than the flagship. Our paired runs put the real 5x-to-20x gap nearer 5.7x than the advertised 4x.
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.
Claude Max 5x is our pick of the heavy band.
Claude Max 5x is for serious daily agent use without the top-tier price; Google AI Ultra 5x is for Antigravity users emptying the AI Pro window.

We have not measured Claude Max 5x on its own plan; its card below points at the closest graded evidence.
We have not measured Google AI Ultra 5x on its own plan; its card below points at the closest graded evidence.
Half the price of Max 20x for the same models, harness and 5-hour rolling window, and for one person running one agent hard this rung clears most days. Worth knowing: our paired runs put the real gap between 5x and 20x nearer 5.7x than the advertised 4x, so the top rung buys more than its label says.
Pros
- The same models and window as the $200 tier
- Clears most days of serious agent work
- Half the price of the top rung
Cons
- Not enough headroom for several agents at once
- Same promotion caveat as the rest of the Claude ladder
Best for Serious daily agent use without the top-tier price.
How far it goes: we have not measured this plan

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.
