1. Core Advantages of the ChatGPT Pro $100 Plan

Recently, OpenAI finally launched the much-anticipated $100 membership tier — the ChatGPT Pro plan (Pro 5x) that had been teased for the past two months as the answer to Claude Max Lite.

For heavy developers and AI enthusiasts, this new ChatGPT Pro plan is highly attractive, with core advantages including:

1. Exclusive access to the GPT-5 Pro model: experience the current top-tier logical reasoning and generation capability.
2. 5x Codex quota: fully covers high-frequency programming and code generation needs.
3. OpenClaw support: the generous Codex quota can be used directly in advanced plugins and local development environments like OpenClaw.
4. Price advantage (vs. Claude Max): compared with the $125 Claude Max 5x, the $100 ChatGPT Pro plan has no extra "Apple tax" when purchased through the iOS client, making it better value.

2. Quota Changes for ChatGPT Pro, Plus & Business (Latest April Adjustments)

Alongside the Pro plan launch, OpenAI officially suspended the earlier Codex promotion yesterday (April 10, 2026). This means basic members' quotas saw major adjustments:

• Plus quota cut: Plus users' Codex quota has been cut by roughly 40% compared with the promo period. When using local Codex coding now, you'll clearly notice the 5-hour quota burning faster (that's not your imagination — it's an official change).
• Business normalized: the previous Business quota structure has been adjusted and now matches Plus.

💡 Note: this change only affects local Codex coding quota — it doesn't affect your other normal ChatGPT features (chatting, image generation, etc.).

For reference:

• Plus Codex quota before:

3. Limited-Time Perk: Upgrading to Pro 5x Before End of May 2026 Is Best Value

The thing everyone cares about most is of course how much quota the new ChatGPT Pro plan actually provides. To promote this tier, OpenAI is currently offering a massive limited-time perk:

Sign up before May 31, 2026, and your Pro 5x Codex quota gets doubled! In other words, for $100 you get roughly 10x the Codex quota of a Plus member — basically the same experience as the old $200 (Pro 20x) plan.

• Pro 5x ($100) current Codex quota:

• Pro 20x ($200) current Codex quota:

When you click to upgrade to Pro in the backend, the system offers $100 and $200 options. We strongly recommend choosing the $100 Pro 5x before May 31 — this is currently the best-value "deal of the deal" window.

4. How to Quickly Handle Your ChatGPT Pro / Plus Upgrade

The Pro 5x membership is roughly 700+ RMB, much friendlier for developers in China compared with the old $200 threshold. If you don't know how to bind an overseas credit card or upgrade, you can use a one-click upgrade tool to safely upgrade your account at nearly the original price.

5. How to Check Your Codex Quota Usage

Want to know your remaining quota at any time? OpenAI offers several convenient ways to check:

1. Web dashboard: After logging in, visit the Codex usage dashboard: https://chatgpt.com/codex/settings/usage

2. Local client (Codex CLI): In the command-line tool, simply type /status to see your current quota at a glance.

3. IDE plugin: Click the local status button at the bottom-left of your editor (e.g., VS Code) to view remaining quota.

6. Conclusion: Do You Really Need to Upgrade to ChatGPT Pro?

If you're a regular user who mainly writes copy and processes data, your current Plus membership is still plenty. But if you fall into one of these two groups, the ChatGPT Pro plan is absolutely worth it:

1. Heavy programmers and developers: especially those who rely on Codex for local code generation.
2. Hardcore OpenClaw (crayfish) users: these advanced tools burn through quota quickly. If your budget allows, go straight to Pro 20x; if you want the best value, make sure to grab the Pro 5x ($100) quota-doubling window before May 31.
