ChatGPT Pro 5x vs Google AI Ultra 5x: choose ChatGPT Pro 5x if coding is the main job. Both cost the same $100/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 5x if coding is the main job. Codex is much easier to follow than Antigravity, and you get every OpenAI model with no 5-hour window.
Choose Google AI Ultra 5x if the Google bundle is the purchase and the coding agent is secondary. It costs the same and includes the broader Google services.
$100 gives Codex one weekly usage bucket with no 5-hour session window. You get every OpenAI model, including Astra. Buy it only if Plus's 5-hour windows are blocking you from doing more work.
Pros
No 5-hour session window
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 Plus 5-hour windows.
How far it goes: we have not measured this plan
Same Codex CLI as ChatGPT Plus with five times its allowance - the Plus scorecards are the closest evidence.
$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.
