not available OpenAI is not selling ChatGPT Pro 20x right now. ChatGPT Pro 5x is still available. Checked 2026-09-24.
SuperGrok Heavy costs $300/mo; ChatGPT Pro 20x costs $200/mo. More usage is expected from the more expensive plan; the question is whether it buys anything else.
ChatGPT Pro 20x vs SuperGrok Heavy: choose ChatGPT Pro. SuperGrok Heavy costs $300/mo; ChatGPT Pro 20x costs $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. It costs $100 less and gives you every OpenAI model in Codex. SuperGrok Heavy gives you more usage of the slow Grok 4.7.
If you need xAI media tools, buy the cheapest Grok plan that includes them. Do not spend $300 for the coding agent.
$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.
The $100 plan already has more Grok usage than we can find a use for. We have no idea what anyone would do with the $300 plan. xAI does not publish a usage multiple. Coding still runs on Grok 4.7. We do not recommend this plan.
Pros
Includes X Premium+
Cons
No use case beyond the $100 plan
No published usage multiple
The same Grok 4.7 coding model
Best for Nobody.
How far it goes: we have not measured this plan
Same Grok CLI as SuperGrok Plus with a bigger allowance - the SuperGrok Plus scorecard is the closest evidence.
