Our verdict
Choose ChatGPT Plus. Both plans give you the same Codex models. ChatGPT Pro 20x charges ten times as much for more allowance.
A bigger allowance is the least $200 should buy. Buy Pro only if you have already proved that Plus stops your work.
$20 gets you Codex with every OpenAI model, including Astra. Luna handles high-volume small tasks at a fraction of the quota. OpenAI's extra resets are getting fewer and fewer, so don't rely on them lasting much longer.
Pros
Every OpenAI model, including Astra
Luna is cheap on quota
Generous allowance while the extra resets last
Cons
Opus 5.5 is stronger at the same price
Astra can drain the whole 5-hour window in one prompt
The current allowance depends on temporary extra resets
Best for People who want Luna for high-volume small tasks.
How far it goes: at least 15 times a week, and more than 100 for the cheapest model
Our whole real-world issues and spec planning pass runs at least 15 times a week, and more than 100 for the cheapest model on this plan, depending on which model you run.
That works out at about under 5c to 28c of the subscription per run, at the list price.
Measured on this plan, at <1% to 6%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
$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
