Official ChatGPT Codex 48-Month Guide: Get It for Only 50 Yuan

Background

OpenAI's latest event is here! ChatGPT Business with 2 seats for $20, with a continuous subscription for 48 months; this is equivalent to 50% off the normal subscription price! Moreover, the quota for Business is twice that of regular Plus, so it's effectively 75% off.

But that's not enough. Today I will teach you an even more cost-effective way to subscribe. By applying with a UK account, each account only costs 50 yuan per month, which is equivalent to 30% of a regular subscription, or 10% if calculated by quota!

First, Prerequisites

1. A UK IP address. In practice, a regular IP works, even common ones, as the current restrictions aren't very strict, but that might change in a few days.
2. A Visa/Mastercard. Domestic Chinese cards won't work; some users say U-cards (crypto cards) are supported.
3. An email address. Any email will do; using your own domain email or a commonly used one is recommended.
4. Your nimble hands.

Second, Practical Steps

Step 1: Register a GPT Account

I won't go into much detail here. You can register using an IP from anywhere, though I recommend using a UK one to avoid issues if risk control becomes stricter later.

Step 2: Enter the Promotion Link Page

Enter through the UK promotion link shared by netizens:

https://chatgpt.com/?promoCode=codestonegb

Step 3: Jump to the Payment Address

This step requires attention. If you click the Upgrade button directly through the link above to enter the payment interface, there is a high probability that the payment will fail. This has been a long-standing issue, likely because OpenAI's risk control is stricter.

Therefore, you need to jump to the Stripe payment interface. You need to press F12 to enter the browser's console, click the "console" menu, and then paste the script I provided below to execute it.

The script is as follows:

1(async function generateAUTeamLink() {
2  console.log("⏳ 正在获取B Session Token...");
3
4  // 自动获取登录凭证
5  let accessToken;
6  try {
7    const s = await fetch("/api/auth/session").then(r => r.json());
8    accessToken = s?.accessToken;
9    if (!accessToken) throw new Error("accessToken 为空");
10  } catch (e) {
11    console.error("❌ 获取 Token 失败：", e.message);
12    return;
13  }
14  console.log("✅ Token 获取成功");
15
16  const COUPON = "codestonegb";
17
18  // ---- 以下为你提供的 Payload（仅修改 workspace_name 动态生成）----
19  const payload = {
20    plan_name: "chatgptteamplan",
21    team_plan_data: {
22      workspace_name: "workspace", // 可自行修改
23      price_interval: "month",     // month 或 year
24      seat_quantity: 2,            // 席位数量，Team 最少 2？1的话是另外种玩法，需要号
25
26    },
27    billing_details: {
28      country: "GB",
29      currency: "GBP"
30    },
31    cancel_url: "https://chatgpt.com/?promoCode=codestonegb",
32    promo_code: COUPON,                            // 注意这里用的是 promo_code 字段
33    checkout_ui_mode: "hosted"
34  };
35
36  console.log("⏳ 正在请求 Stripe 长链接 (US)...");
37  try {
38    const resp = await fetch(
39      "https://chatgpt.com/backend-api/payments/checkout",
40      {
41        method: "POST",
42        headers: {
43          Authorization: `Bearer ${accessToken}`,
44          "Content-Type": "application/json"
45        },
46        body: JSON.stringify(payload)
47      }
48    );
49    const data = await resp.json();
50
51    if (!resp.ok) {
52      console.error(`❌ 请求失败 HTTP ${resp.status}`);
53      console.log("📋 响应详情：", data);
54      return;
55    }
56
57    const hostedUrl = data?.url || data?.stripe_hosted_url || data?.checkout_url;
58    if (!hostedUrl) {
59      console.warn("⚠️ 未找到长链接，原始响应：", data);
60      return;
61    }
62
63    console.log("─".repeat(60));
64    console.log("✅ ChatGPT Team 链接生成成功！（美国）");
65    console.log("📋 Checkout Session ID :", data.checkout_session_id);
66    console.log("📌 计划                : ChatGPT Team (US/USD)");
67    console.log("💺 席位                :", payload.team_plan_data.seat_quantity);
68    console.log("🎟️  优惠码              :", COUPON);
69    console.log("🔗 Stripe 长链接：");
70    console.log(hostedUrl);
71    console.log("─".repeat(60));
72  } catch (e) {
73    console.error("❌ 网络异常：", e.message);
74  }
75})();

If a yellow warning appears: Warning: Don’t paste code into the DevTools Console that you don’t understand or haven’t reviewed yourself. This could allow attackers to steal your identity or take control of your computer. Please type ‘allow pasting’ below and press Enter to allow pasting.

Just manually type: allow pasting

Then press Enter, and paste the code above.

Step 4: Payment

After executing the code above, a Stripe payment link will be displayed. Click it to enter the Stripe payment interface, enter your card number and CVV, and use any address (matching your credit card's billing address) to complete the payment.

Finally

The overall process is relatively simple. If you have any questions, feel free to ask me.
