- Pro 200: on your own account ¥1,300 ≈ 193.75 USDT · ready-made ¥1,349 ≈ 201.05 USDT
- Pro 100: on your own account ¥850 ≈ 126.68 USDT · ready-made ¥899 ≈ 133.98 USDT
- Codex credits: 500 credits per pack, ¥180 ≈ 26.83 USDT; 1–20 packs per order, Plus or Pro accounts only
The arithmetic first: what the extra 67.07 USDT buys
OpenAI’s Help Center only says that Pro 200 includes more usage than Pro 100 and that Pro 500 has the most; it no longer publishes multiples. The usable numbers come from OpenAI’s Thibault Sottiaux on X, as reported: Pro 100 is about 5x Plus and the new Pro 200 about 10x. Divide each price by its multiple and you get the price of one Plus-worth of usage:
| Plan | OpenAI price | vs Plus (reported) | Per Plus-worth at OpenAI | Our top-up | Per Plus-worth here |
|---|---|---|---|---|---|
| Plus (baseline) | $20 | 1x | $20 | 27.58 USDT | 27.58 USDT |
| Pro 100 | $100 | 5x | $20 | 126.68 USDT | 25.34 USDT |
| Pro 200 (new allowance) | $200 | 10x | $20 | 193.75 USDT | 19.38 USDT |
At OpenAI’s prices every tier costs $20 per Plus-worth, so there is no bulk discount there; at our current prices the cheapest per Plus-worth is Pro 200 (new allowance), at about 19.38 USDT. For the upgrade itself: Pro 200 costs 1.53x as much as Pro 100 here for a reported 2x the usage, so one Plus-worth of usage drops from about 25.34 USDT to about 19.38 USDT, roughly 24% cheaper. Put another way, the extra 5 or so Plus-worths cost about 13.42 USDT each, less than a whole Plus top-up (27.58 USDT). At OpenAI the step from Pro 100 to Pro 200 is $100 a month; between our two top-ups it is only 67.07 USDT.
The multiples are rough Codex / Work ratios that OpenAI does not publish, not official thresholds; GPT-6 Pro in chat is counted separately (see the table below). A cheaper unit only matters if you actually use the usage.
Pro 100 vs Pro 200, line by line
Everything here comes from OpenAI’s Help Center, pricing docs and release notes; the multiples and the new message count are reported figures and are marked as such.
| Pro 100 (formerly Pro 5x) | Pro 200 (formerly Pro 20x) | |
|---|---|---|
| OpenAI price | $100 a month | $200 a month |
| Our top-up (your own account) | ¥850 ≈ 126.68 USDT | ¥1,300 ≈ 193.75 USDT |
| Our ready-made account | ¥899 ≈ 133.98 USDT | ¥1,349 ≈ 201.05 USDT |
| Overall usage (OpenAI) | More than Plus | More than Pro 100 |
| Overall usage (reported) | About 5x Plus | About 10x Plus (new allowance) |
| GPT-6 Pro in chat | Yes, sharing one weekly allowance with GPT-5.6 Sol Pro (last published 2026-09-28: 50 a week) | Yes, its own weekly allowance (reported at 100 a week on the new allowance) |
| GPT-5.6 Sol Pro | Shares the weekly allowance above | Its own daily allowance (last published 2026-09-28: 170 a day) |
| After the GPT-6 Pro weekly limit | No automatic switch documented; a model at its limit is unavailable until it resets (ChatGPT shows when) | ChatGPT switches to GPT-5.6 Thinking (Medium) |
| Thinking levels in chat | Same: Medium, High, Extra High and Pro | |
| Five-hour limit in Codex / Work | Same: none for now; weekly limits may apply | |
| dots (always-on agents) | Same: rolling out (18+, not in the EEA, Switzerland or the UK at launch, not counted toward usage for the first month) | |
| Ultrafast | Neither: Pro 500 only (GPT-6 Astra, GPT-6.1 Sol); credits do not unlock it | |
| Codex credits | Both can buy them; drawn after included usage | |
In one line: Pro 200 adds no features. It adds usage, and a roomier split for the Pro models in chat: GPT-6 Pro gets its own weekly allowance, Sol Pro is counted per day, and when GPT-6 Pro runs out ChatGPT carries on with GPT-5.6 Thinking. On Pro 100 both Pro models draw from one weekly pool, and no automatic fallback is documented.
About October 30: that change only cuts Pro 200 subscriptions that were active at some point from September 22 through 10 a.m. Pacific on September 29. If you upgrade from Pro 100 now, you start on the new allowance and October 30 changes nothing for you; details in ChatGPT Pro 200 on October 30.
Signs Pro 100 is too small for you
- The shared Pro-model allowance runs out before the weekly reset. On Pro 100, GPT-6 Pro and GPT-5.6 Sol Pro draw from one weekly allowance. If you regularly see a Pro model unavailable mid-week with a reset time, that is the clearest signal. OpenAI says limits cannot be bypassed through a setting, and Support cannot reset them.
- You hit the weekly limit in Codex or ChatGPT Work. Pro plans have no five-hour window, but weekly limits may apply. Check Settings → Usage (Usage & Billing in the Codex app): if you reach the end before the week does, Pro 200 reportedly gives about 2x the room.
- You run long tasks or use Fast mode. OpenAI’s pricing docs say cloud tasks may use more of the allowance than local messages, and Fast mode uses included usage at 2.5x. Parallel Codex tasks and habitual Fast mode drain Pro 100 quickly.
- You buy 3 or more packs of credits a month. At today’s prices the 67.07 USDT difference buys 2 packs of Codex credits (1,000 credits); beyond that, Pro 100 plus credits costs more than Pro 200 (see the next table).
- Waiting for resets costs you more than the step. The upgrade is about 2.24 USDT a day. If one blocked afternoon is worth more than that to you, the maths is short.
The cheaper alternative: Pro 100 plus Codex credits
OpenAI’s pricing docs say Plus and Pro users who hit a limit can buy credits instead of upgrading: included usage is spent first, then credits. This table uses today’s prices (refreshed hourly; the pricing page is authoritative) to show Pro 100 plus a few packs a month against Pro 200:
| Packs added a month | Pro 100 + credits | vs Pro 200 top-up (193.75 USDT) |
|---|---|---|
| 0 (0 credits) | 126.68 USDT | saves 67.07 USDT |
| 1 (500 credits) | 153.51 USDT | saves 40.24 USDT |
| 2 (1,000 credits) | 180.33 USDT | saves 13.42 USDT |
| 3 (1,500 credits) | 207.16 USDT | costs 13.42 USDT more |
| 4 (2,000 credits) | 233.98 USDT | costs 40.24 USDT more |
Up to 2 packs a month, Pro 100 plus credits is cheaper; at 3 or more every month, upgrade to Pro 200. Two caveats:
- Credits do not reach chat. They cover Codex, ChatGPT Work and ChatGPT for Word, Excel and PowerPoint only. If the shared GPT-6 Pro allowance in chat is your bottleneck, no number of packs helps; only Pro 200 does.
- Credits do not expire monthly. They last 12 months (non-transferable), so uneven usage often costs less than the table suggests.
What one 500-credit pack buys on each model is worked out in Codex limit: credits or upgrade?; ordering is covered in Buy Codex credits.
Upgrade Pro 100 to Pro 200 on the same account (6 steps)
OpenAI’s Help Center says to use your existing account when you change plans, and our Pro 200 top-up accepts Pro accounts, so an unexpired Pro 100 can move up. Because it stays your account, chats, memory, custom instructions, GPTs and Projects are untouched; only the plan changes.
- Check your account: Sign in at chatgpt.com and look under Settings → My Plan: Pro (Pro 100) is fine, as long as the account signs in normally. The Pro 200 top-up accepts Free, Plus and Pro accounts, for a new subscription, a renewal or an upgrade, so an unexpired Pro 100 can move up directly.
- Pick the product: On the pricing page choose ChatGPT Pro 200 as a top-up on your own account and check the price and stock.
- Submit sign-in data, checked first: Submit the sign-in data the order page asks for (a session or cookie JSON). It is checked before you pay, and if the check fails you pay nothing. You keep your password.
- Pay in USDT: TRC20 or BEP20. Send exactly the amount shown on the order page; the amount identifies your order. Each order covers 30 days.
- Wait for activation: Usually 5 to 30 minutes. The sign-in data is used for this top-up only and cleared automatically after delivery.
- Check and switch off the duplicate renewal: Refresh chatgpt.com, confirm Pro 200 under Settings → My Plan and the new limits and reset times under Settings → Usage; your chats, memory and GPTs are all still there. If your Pro 100 renews automatically on the web, the App Store or Google Play, switch auto-renew off where you bought it so you are not charged twice.
What about the Pro 100 days you have left? That is decided by OpenAI’s billing; we do not promise any credit for it or interpret OpenAI’s rules. If you are in no hurry, upgrading near the end of your Pro 100 period leaves the fewest days at stake; if you hit the wall every day, upgrading now buys back time. Turn off auto-renew wherever your Pro 100 was bought so you are not charged twice. The full buying guide (prices, both ways to buy, after-sales) is How to buy ChatGPT Pro 200; if your card keeps being declined at OpenAI, see card declined or unsupported country.
Every month after that: each order covers 30 days, with reminder emails 7, 3 and 1 day before it ends; renewing a Pro 200 top-up is a new order on the same account, checked before you pay as before. How to keep it from lapsing: Renew ChatGPT Pro 200.
The other route: a ready-made Pro 200 account
A ready-made account already has Pro 200 active; one account per order, for one person, and per the product description you can bind your own email. It suits three kinds of buyer: you would rather not submit your own sign-in data; you want a work account separate from your personal one; or your account does not qualify for a top-up.
- Flow: pay in USDT → enter a delivery email on the order page → click the verification email Cloudflare sends → our team delivers by hand; the order page shows 30 minutes to about 4 hours. Change the password first, then check Settings → My Plan.
- Price: first month ¥1,349 ≈ 201.05 USDT, 7.31 USDT more than the top-up; renew by messaging Telegram @ccnb1937 with your order ID, at the Pro 200 top-up price (193.75 USDT).
- Old chats do not move: OpenAI does not merge accounts or move subscriptions, memory or GPTs between them; see ready-made vs your own account.
Keep everything in your Pro 100 account: top up. Want a separate account or no sign-in data handed over: ready-made. Pro 200 itself is identical either way.
When to stay on Pro 100 (or step back down)
- The shared weekly allowance is usually enough. You rarely wait for a Pro-model reset and rarely hit the Codex weekly limit. Pro 200 adds no features, so you would only pay more.
- You go over only in Codex, and not often. Up to 2 packs of credits a month cover it for less than the upgrade, and leftovers stay usable for 12 months.
- You need the big allowance only in crunch months. Take Pro 200 that month and Pro 100 otherwise: OpenAI bills Pro monthly and each of our orders covers 30 days, so nothing locks you in.
- Stepping down: let Pro 200 run out, then order the Pro 100 top-up (Pro accounts qualify) and save 67.07 USDT a month; direct OpenAI subscribers change plans in Settings → My Plan. Credits you bought stay usable.
- On a grandfathered Pro 200: your old allowance runs through October 29; do not step down yet. Try a week on the new allowance after October 30 first.
If Pro 200 is not enough either
The only tier above is Pro 500 (top-up ¥3,599 ≈ 536.37 USDT): the highest allowance, reportedly about 25x Plus, and the only tier with Ultrafast (GPT-6 Astra, GPT-6.1 Sol, using included usage at 8x). If you hit the new Pro 200 limit every week or need Ultrafast, read How to buy ChatGPT Pro 500; all three tiers side by side are in ChatGPT Pro 100 vs 200 vs 500.
Before you order
- Checked before you pay: top-ups verify your sign-in data first, and you pay nothing if the check fails. The data is used once and cleared after delivery; your password stays with you.
- Refunds: if an OpenAI regional policy change makes the service unavailable, you get a refund for the unused days, processed within 1 business day. Bans caused by breaking OpenAI’s usage policies are not refunded. Contact the bottom-right live chat promptly if anything goes wrong.
- Track record: ClaudeMax has operated since November 2024 and has served more than 20,000 users (our own figure). We are not OpenAI, nor an authorized reseller; OpenAI sets the allowances and can change them.
- OpenAI’s terms prohibit sharing account credentials, reselling access and automated extraction, and OpenAI may restrict access. One account per person; change a ready-made account’s password at once; never lend or split it; avoid signing in from many different countries.
- Prices follow cost, exchange rate and stock; the order page is authoritative. Every tier with three-month totals: ChatGPT Pro prices, October 2026; more answers in the FAQ.
