1. Core Differences Between ChatGPT Pro 5x and 20x
When looking up tutorials on how to upgrade to ChatGPT Pro, the biggest dilemma for most people is which tier to choose. Currently, the biggest difference between Pro 5x ($100/month) and 20x ($200/month) is the quota cap for Codex (code writing and complex computation).
Pro 5x can be thought of as a Pro Lite version. To make it easier to understand at a glance, see the comparison table below:
| Comparison Dimension | ChatGPT Plus ($20) | ChatGPT Pro 5x ($100) | ChatGPT Pro 20x ($200) |
|---|---|---|---|
| Base model capability | Includes base GPT-4o, etc. | Includes the most powerful GPT-5 Pro model | Includes the most powerful GPT-5 Pro model |
| Daily Codex quota | Base quota | 5x that of Plus | 20x that of Plus |
| 🎁 Limited-time promotional quota | No change | Boosted to 10x that of Plus | Also boosted extra during the promotion |
💡 Hidden benefit: The official store is currently pushing ChatGPT Pro 5x membership hard. Before May 31, 2026, the 5x tier actually enjoys a 10x Codex quota!
2. Advanced Features and Risk-Control Notes Included in ChatGPT Pro
Apart from usage quotas, no matter which method you use to upgrade, the feature experience of 5x and 20x on the Web is completely identical. All Pro plans include priority access to the following advanced features:
- Pro models (including the latest GPT-5)
- Codex (advanced coding and logic processing)
- Deep Research
- Image generation
- Memory
- File upload and data analysis
# ⚠️ Note: ChatGPT Pro accounts are subject to extremely strict risk control
Before looking at tutorials on how to upgrade to ChatGPT Pro, please make sure you understand OpenAI's terms of use. Although Pro offers "unlimited access" to GPT-5 and older models, Pro members face far stricter risk control than Plus, and the official store has set up rigorous safeguards. The following behaviors are prohibited:
- Abusive behavior (such as scraping data automatically or programmatically).
- Sharing your account, or letting any other person use it (extremely likely to get banned!).
- Reselling access, or using ChatGPT to provide API support to third-party services.
3. Core Tutorial: How to Upgrade to ChatGPT Pro in China?
Now that you understand the differences, let's get to the heart of this article: How can users in China upgrade to ChatGPT Pro smoothly?
You can upgrade on ChatGPT's official pricing page or in "Settings → account". Once you select a plan, the new usage cap takes effect immediately. Currently, users in China mainly have the following three upgrade methods:
# Method 1: One-click upgrade through a third-party system (most recommended / least hassle)
For users in China without an overseas credit card, this is the fastest way. You can complete the Pro subscription in one click through a professional upgrade platform, avoiding lags or rejected payments.
🚀 GPT Plus / Pro one-click upgrade channel: https://gptplus.org.cn (opens new window)
# Method 2: Pay with an international credit card
If you have an international credit card that supports foreign-currency payments (such as Visa, MasterCard, or an overseas virtual credit card), you can bind it directly on the Web. Note that the billing address should ideally match the IP environment you are using.
# Method 3: In-app purchase via Apple iOS gift cards (mind the restrictions)
You can purchase a US-region Apple Gift Card, top up your Apple ID, and then subscribe through the ChatGPT app on iOS.
🚨 Pitfall-avoidance guide: iOS cannot skip directly from the "free plan" to "Pro membership"! If you are a free user, opening the iOS app will only show the Go and Plus upgrade options (as shown below). Official rule: If you want to upgrade directly from the free plan to the Pro plan, you must do it through the Web (https://chat.openai.com (opens new window)).
4. Frequently Asked Questions (FAQ) About Upgrading to ChatGPT Pro
(1) Who is ChatGPT Pro suitable for? ChatGPT Pro is designed for professionals who rely on AI for high-stakes, complex work. If you frequently use "Deep Research", "Codex code writing", and the latest Pro models (such as GPT-5) in your daily work, the Pro plan will dramatically improve your productivity.
(2) What exactly is the core difference between the $100 tier and the $200 tier? The core capabilities of the two Pro plans (model intelligence, tool library) are exactly the same. The only difference is usage quota. According to the official Codex pricing page:
- Pro $100 (5x): Normally 5x that of Plus, temporarily boosted to 10x during the limited-time promotion (until May 31, 2026).
- Pro $200 (20x): Normally 20x that of Plus, also boosted extra during the promotion.
(3) Will the existing $200 Pro plan be discontinued or changed in the future? No. The $200 Pro plan remains the highest usage tier (its Codex usage has already been boosted to 20x that of Plus). The new $100 plan simply offers a more cost-effective option for users who want Pro's powerful capabilities but don't need 20x usage in daily work.
