1. The ChatGPT Pro Plan Is Officially Live: An Overview of Core Advantages
Recently, OpenAI finally launched the long-awaited $100/month ChatGPT Pro plan. In the past two months, industry reports had said OpenAI would release a Lite plan to compete with Claude Max (i.e., the Pro Lite membership). Now the other shoe has dropped, and the price is exactly half of the top-tier plan.


This time, the $100-tier (Pro 5x) ChatGPT Pro plan brings you two core advantages:
- Unlock the latest model: Fully unlocks the more powerful GPT-5 Pro model.
- Compute quota surge: Provides up to 5x the Codex programming quota of a Plus membership, and this Codex quota works perfectly with third-party tools such as OpenClaw.
2. ChatGPT Pro vs Claude Max: Which Offers Better Value?
Many users are torn between the ChatGPT Pro plan and Claude Max. Compared with Claude Max, the $100 ChatGPT Pro has a clear price advantage:
- No "Apple tax": ChatGPT Pro has no additional Apple tax surcharge on iOS in-app purchases — a solid $100.
- The competitor is pricey: By comparison, Claude Max 5x's in-app purchase price is as high as $125. For users who rely heavily on code generation, ChatGPT Pro is clearly the better deal.
3. Codex Quota Changes Across ChatGPT Pro, Plus, and Business
With the launch of the Pro plan, OpenAI officially reallocated the overall subscription quota pool.
- Plus quota reduced (back to normal): Plus users previously had a larger Codex quota because of an official Codex promotion. That promotion was officially paused on April 10, so the Plus quota has shrunk by roughly 40%.
- Business quota aligned: The Business version's quota has now been scaled back to match Plus.
Note: You may now clearly feel that the 5-hour quota is consumed quickly when using Codex. This is the result of the official adjustment, not your imagination. However, rest assured, this only affects local Codex programming calls — it has absolutely no impact on your other conversation and generation features in ChatGPT Plus/Pro.

4. Limited-Time Benefit: Upgrade to ChatGPT Pro Before May 31 and Double Your Quota
What everyone cares about most is the specific quota of the new ChatGPT Pro $100 plan (Pro 5x).
⭐ Key reminder: official promotion-period benefit To promote the new ChatGPT Pro plan, the official side has launched a limited-time doubling event. If you activate Pro 5x membership before May 31, 2026, your quota will be directly doubled — equivalent to getting 10x a Plus Codex quota!

For comparison, the Pro 20x ($200) Codex quota is as follows:

When you click to upgrade Pro membership in the backend, the system offers two options: $100 (Pro 5x) and $200 (Pro 20x). Activating the $100 Pro 5x before May 31 is clearly the most cost-effective option right now, because the doubled Codex quota is already nearly identical to the $200 plan.


5. How to Quickly Upgrade to the ChatGPT Pro / Plus Plan?
Currently, Pro 5x membership is roughly 700+ CNY, a dramatically lower barrier than the previous Pro 20x, making it extremely suitable for programmers, developers, and high-frequency code users. Of course, if you're an extremely heavy user who burns through resources on OpenClaw (Little Lobster) and similar tools, going straight for Pro 20x in one step is still the best choice.
