ChatGPT Pro 200 has reopened for new subscriptions. New subscribers who are not eligible for grandfathering receive a lower allowance. Eligible users retain their previous allowance through 29 October 2026, then move to the lower allowance at the same price. Check what your account receives now and after the transition.

What you need to know

Check your subscription notice and usage dashboard before changing plans. Pro 200 still costs US$200 per month in OpenAI’s reference pricing. The transition affects included usage; a ratio against Plus alone does not tell you how many real tasks you can complete.

What Tibo’s Plus and Pro comparison says

In an X post, Tibo (@thsottiaux) says OpenAI is increasing what users can do across Plus and Pro while changing the relative tiers to Plus at 1×, Pro 100 at 5× and Pro 200 at 10×. He describes existing subscribers keeping the previous 20× multiplier temporarily and receiving additional credits. The help page supplies the eligibility conditions.

That announcement explains the relative comparison. It does not specify a credit quantity or expiry, or a fixed number of messages and completed jobs. Readers should check their own notice for the offer that applies to their account.

Text: Plus = 1X / Pro 100 = 5X / Pro 200 = 10X

Excerpt from the original post; line breaks displayed as slashes. The dated transition terms come from OpenAI’s current Pro help page.

Why 20× becoming 10× needs context

A multiplier compares a plan with a baseline. If the baseline changes, the multiplier alone cannot establish the change in absolute capacity. As a purely mathematical example, 20 times a baseline of one unit equals 10 times a baseline of two units. That illustration does not claim OpenAI has doubled the Plus allowance.

There is also a distinction between the allowance you receive and the amount of useful work an updated model completes with it. Efficiency could affect the second measure. It does not answer what your account is entitled to receive.

OpenAI’s help page confirms a lower included allowance for affected Pro 200 subscriptions. A changing baseline does not explain that reduction away. A task-capacity percentage would require a separate, representative comparison.

Who keeps the old allowance, and for how long?

Eligibility covers Pro 200 subscriptions active at the cutoff or during the preceding seven days. Retaining the previous allowance through 29 October requires an active Pro 200 subscription. Afterwards, usage falls at the same monthly price.

The FAQ leaves the exact cutoff date unstated. Affected users receive an email; use that notice to check eligibility.

The monthly price ladder

OpenAI’s published reference prices are:

  • Plus: US$20 per month.

  • Pro 100: US$100 per month.

  • Pro 200: US$200 per month.

  • Pro 500: US$500 per month, with Astra Ultrafast access.

For Australian readers, these are USD reference figures. OpenAI supports AUD billing and localised web pricing; mobile subscriptions are managed by Apple or Google. Use the currency and total on your own bill or checkout when comparing the actual monthly cost.

How to judge the allowance against your work

OpenAI’s pricing documentation says usage depends on the model, task complexity, context, tools and whether work runs locally or in the cloud. Work and Codex share usage. API token prices are separate and should not be used to calculate the tasks included in a subscription.

Keep a short record of the work you actually do: which model you choose, how often you reach a limit, and whether the output is usable. A larger allowance has less value if most of your work already fits within a cheaper plan. Conversely, a deadline interrupted by a limit has a cost that a monthly price comparison can miss.

What to do before 29 October

Save your account’s transition notice and compare it with the usage dashboard. Reassess the plan against a representative week of work, including time spent correcting outputs. Check the terms of any additional credits separately before treating them as permanent capacity.

The decision should follow your workload and the allowance your account will receive after the transition. This report explains the published changes; it does not measure task capacity or verify a particular subscriber’s eligibility.
