ChatGPT Pro 20x vs Google AI Ultra 20x: choose ChatGPT Pro if coding is the main job. Both cost the same $200/mo. Prices are the providers' own list prices, and the verdict is ours rather than a score. The two plans are compared on what a week of real coding tasks fits, not on a feature list.Measured
Our verdict
Choose ChatGPT Pro if coding is the main job. Codex is much easier to follow than Antigravity, and Google still has no top-tier model for hard work.
Choose Google AI Ultra 20x only if its storage and Google services matter more than the agent. Antigravity remains the weak part of the plan.
$200 gives Codex one weekly usage bucket with no 5-hour session window. It has four times the allowance of Pro 5x. You get every OpenAI model, including Astra. Buy it only if the Pro 5x weekly limit is blocking your work.
Pros
No 5-hour session window
Four times the Pro 5x allowance
Every OpenAI model, including Astra
Luna for high-volume small tasks
Cons
No Opus 5.5 or Fable
Best for Codex users blocked by the Pro 5x weekly limit.
How far it goes: we have not measured this plan
Same Codex CLI as ChatGPT Plus with twenty times its allowance - the Plus scorecards are the closest evidence.
$200 buys the highest Gemini usage and the largest Google bundle. It does not improve Antigravity or the available models. Buy this only if the lower Google plans cannot provide enough usage.
Pros
The highest Gemini usage
The largest Google services bundle
Cons
The same rough Antigravity agent
The same models as the $20 plan
Best for People who need maximum Gemini usage and will use the Google bundle.
How far it goes: we have not measured this plan
Same Antigravity CLI as AI Pro with a far bigger allowance - the AI Pro scorecards are the closest evidence.
