Claude 的 $200 套餐宣传为“Pro 限额的 20 倍”，但这个倍数只适用于 5 小时用量窗口；每周限额实际上只有 $100 套餐的约 2 倍。OpenAI 澄清，其 Codex Pro 的 20 倍是 Plus 用量的精确 20 倍，按每周限额计算，且没有 5 小时限制。
For clarity, while both are called 20X, in Codex they apply specifically to weekly usage limits. And we also don't have 5h limits for both Pro plans. The Pro 20X is quite precisely 20X the usage of the Plus subscription, so it does exactly what it says on the tin.
The whole “20x” in Claude’s pricing is so misleading. The $100 plan says 5x Pro limits, while the $200 plan says 20x Pro limits. That makes it sound like you’re getting 4x the usage. But the 20x applies only to the 5-hour usage window. The weekly limit is basically just 2x the $100 plan. I spent way too much time digging through the internet and Reddit to figure this out. They could’ve just stated the limits directly instead of marketing it as “20x.” That alone would’ve saved me hours of confusion.
