OpenAI is changing how much more usage each Codex plan gives you compared with the base plan. In a post on X, Tibo (@thsottiaux), who posts about Codex, laid out the new ratios. Plus is 1x. Pro 100 is 5x. Pro 200 is 10x.

Pro 200 subscriptions had been paused. Tibo says they are reopening.

What changed

The post says OpenAI is shipping several things on DevDay that raise what you can do on both Plus and Pro. It says “a lot of compute is online” for this. The floor goes up, and the gap between plans shrinks.

Here is the part that matters if you already pay. Existing subscribers keep the 20x multiplier “for a bit,” according to the post. They also get additional credits. The post frames this as easing the change, and says everyone ends up with more in the end.

Read that carefully. A multiplier is a ratio against Plus, not an amount. If Plus itself gets bigger, a 10x plan can still hold more than an old 20x plan did. The post does not say whether that happens.

What the post does not say

The post leaves out several things a builder needs:

  • The actual usage numbers behind 1x, 5x, or 10x.
  • How long “for a bit” lasts for existing plans.
  • How many credits existing subscribers receive.
  • Any price change.

I could not find these in the material I reviewed. Treat the ratios as a direction, not a budget.

Who should care

If you are on Plus, the floor is rising, so your day-to-day allowance should not shrink. That is the post’s claim, and it gives no figures.

If you are on Pro 200 already, the 20x multiplier is temporary. The date it ends is unpublished. If you are on Pro 100, the post does not say what your multiplier was before, so compare against your own usage rather than the label.

If you were waiting to buy Pro 200, it is available again. Note that it is now sold as 10x Plus.

This also follows OpenAI’s earlier decision to bring back Codex’s 5-hour cap for Plus users. Limits at OpenAI have moved often. Plan on them changing again.

What to do next

Do not upgrade or downgrade on the ratio alone. Run one bounded task before and after the change, such as fixing the same failing test suite in a repo you know well.

Record three things each time: the share of your allowance it used, how many times you had to correct the agent, and whether you hit a limit before finishing. If your usage barely moves on your real work, the cheaper plan is enough. If you hit the limit mid-task, that is the signal to move up.

Check your account’s usage page and billing settings after the change lands. The post does not name a specific place where new limits appear, so look for the numbers there before your temporary 20x runs out.
