How to buy ChatGPT Pro 100 (2026): price, top-up or ready-made account, who it’s for, and when to step up to Pro 200

How much is ChatGPT Pro 100? Our price, OpenAI’s price, and cost per unit of usage

OpenAI sells Pro in three monthly tiers, $100, $200 and $500, with no annual billing and no paying months ahead; Pro 100 is the entry tier. On usage, the Help Center says only that Pro 200 includes more than Pro 100 and Pro 500 the most. Divide each monthly price by the multiple reported in the press (Codex and Work usage relative to Plus) and you get the price of one “Plus-worth” of usage:

How to read it: at OpenAI’s prices every tier costs about $20 per unit, so the differences come from our pricing. At our prices a unit of usage on Pro 100 costs about 25.34 USDT, less than buying Plus on its own (27.58 USDT). Per unit of usage, Pro 200 costs less than Pro 100 at our prices (19.38 USDT against 25.34 USDT), but only if you would really use that much every month. At today’s prices the cheapest unit on our list is Pro 200 (new allowance), about 19.38 USDT. The multiples are press-reported rough ratios for Codex and Work, not official figures; GPT-6 Pro in chat is counted separately, and Settings → Usage is the authority for your own account.

Against OpenAI’s own price: our top-up is 126.68 USDT. That is 26.68 USDT more than OpenAI’s $100 list price, taking 1 USDT ≈ 1 USD (the list price excludes foreign-card fees and taxes). The difference pays for the service: no card that chatgpt.com has to accept, payment in USDT, and a check of your account before you pay. This route exists for buyers whose card is declined at chatgpt.com or whose country is not supported; see Card declined or country unsupported.

What does Pro 100 include? (OpenAI’s wording)

• Everything Pro has. The Help Center lists Pro models, Codex, deep research, image creation, memory and file uploads on all three tiers. Pro 100 differs from Pro 200 and Pro 500 in usage allowance and Ultrafast, not in features.
• Four thinking levels and GPT-6 Pro in chat. Plus gets Medium and High; Pro gets Medium, High, Extra High and Pro. GPT-6 Pro, powered by GPT-6 Astra, is available on Pro 100, while Plus has GPT-6 Astra only in ChatGPT Work and Codex.
• One shared weekly allowance for the Pro models (the difference from Pro 200). On Pro 100, GPT-6 Pro and GPT-5.6 Sol Pro draw from one weekly allowance, and switching between them does not add messages. On Pro 200 they are counted separately, and running out of GPT-6 Pro drops you to GPT-5.6 Thinking (Medium). OpenAI no longer publishes counts: the last published figure for Pro 100, 50 a week across both models on 2026-09-28, has since been removed from the Help Center, so go by what your account shows.
• No five-hour limit in Codex and ChatGPT Work. OpenAI’s pricing docs say Pro plans currently have none, though weekly limits may apply. For contrast, the Plus estimates per five hours, in local messages: GPT-6 Astra 5–45, GPT-6.1 Sol 15–160, GPT-6 Sol 15–150, GPT-6 Luna 350–3,000.
• GPT-6 Sol with Intelligent UI in chat. Since October 7 the Chat tab on paid plans has been moving to GPT-6 Sol, whose answers can mix text, visuals and interactive elements. Intelligent UI works from Instant through Extra High; Pro thinking stays on GPT-6 Astra and does not support it. What each plan gets is in GPT-6 and Intelligent UI in ChatGPT.
• Dot, the always-on agent (dots). Rolling out to eligible Pro users aged 18 and older on every Pro tier, excluding the EEA, Switzerland and the UK at launch. OpenAI’s plan comparison lists it as not included on Plus.
• Composer predictions in Codex (beta). Since October 9, for personal Pro users aged 18 and older: in local and SSH threads of the Codex desktop app using GPT-6 Astra or GPT-6.1 Sol, Codex suggests your next message. During the beta, generating predictions does not count toward Codex limits or use credits; messages you send do.
• Credits for overflow. Included usage first, then credits, which work in Codex, ChatGPT Work and ChatGPT for Word, Excel and PowerPoint, last 12 months and cannot be transferred. They do not add GPT-6 Pro in chat.
• No Ultrafast. Ultrafast for GPT-6 Astra and GPT-6.1 Sol is Pro 500 only, and buying credits on Pro 100 does not unlock it.
• Hitting a limit is not a ban. OpenAI says a usage limit does not end your subscription or restrict your account; wait for the reset or use another model. Support cannot reset limits.

Is Pro 100 enough? Who should buy it, stay on Plus, or go straight to Pro 200 or Pro 500

Pro 100 is the right call when:

1. Plus hits the five-hour limit in Codex most days. You code or run agents in Codex or ChatGPT Work every day. Pro plans have no five-hour limit, and Pro 100’s allowance is reported at about 5x Plus.
2. You need Extra High thinking, Pro thinking or GPT-6 Pro in chat. Plus has none of the three and credits do not unlock them; Pro 100 is the lowest Pro tier and has all three.
3. It is your first month on Pro and you do not know your usage yet. Pro is monthly only, so you choose again every billing period: run a month on Pro 100, watch Settings → Usage, then stay or move up.

Stay on Plus when:

• You mostly chat. Medium and High thinking covers it and you rarely hit a limit: Plus (¥185 ≈ 27.58 USDT) is enough.
• Codex runs over only now and then. Add Codex credits to Plus first. At our prices, Plus with up to 3 packs of credits a month still costs less than Pro 100, but credits do not unlock Extra High, Pro thinking or GPT-6 Pro in chat. The full comparison is in ChatGPT Plus vs Pro 100.

Go straight to Pro 200 or Pro 500 when:

• The shared weekly allowance runs out mid-week. If GPT-6 Pro and GPT-5.6 Sol Pro are what you use most, take Pro 200 (¥1,300 ≈ 193.75 USDT), which counts them separately. Reports put Pro 200’s weekly GPT-6 Pro cap in chat at about 100 on the new allowance; that is not an official figure. See Pro 100 or Pro 200 and How to buy ChatGPT Pro 200.
• You hit Pro 200’s limit every week, or you need Ultrafast: Pro 500 (¥3,599 ≈ 536.37 USDT); see How to buy ChatGPT Pro 500.

Pro 100 plus Codex credits, or Pro 200? The sum only works when the overflow is in Codex or ChatGPT Work, because credits do not add GPT-6 Pro in chat. At our prices the Pro 200 top-up costs 67.07 USDT more than the Pro 100 top-up, and one pack of 500 credits is 26.83 USDT, so adding up to 2 packs of Codex credits a month (500 credits each) to Pro 100 still costs less than Pro 200; at 3 or more a month you pay at least as much as Pro 200, so take Pro 200. Credits last 12 months, so what you do not use this month carries over. The pack-by-pack table is in Pro 100 or Pro 200; ordering is covered in Buy Codex credits.

Do not buy Pro 100 when:

• You want to split one account between several people. OpenAI’s terms prohibit sharing credentials and reselling access, and shared use is how accounts get restricted.
• You want an annual plan or to pay several months at once. Pro is monthly only, and each order here covers 30 days.

Two ways to buy: top-up on your own account, or a ready-made account

In one line: keep your history with a top-up; take a ready-made account if you would rather not submit sign-in data or want a separate work account. The ready-made premium, about 7.31 USDT, applies to the first month only. More on the trade-off in Ready-made account or your own?

Either way you pay in USDT on TRC20 or BEP20, so no card has to be accepted by chatgpt.com. New to it? The USDT payment guide goes through network, exact amount and confirmation step by step.

Before you order: account state, sign-in data, auto-renewal

Open Settings → My Plan on chatgpt.com and find your row:

• Where the sign-in data comes from: the order page shows you. For ChatGPT it currently asks for a session JSON: sign in to ChatGPT in the same browser, open chatgpt.com/api/auth/session, press Ctrl/Cmd + A and Ctrl/Cmd + C, and paste it into the form. No password is needed.
• Only into the order form: never paste it into a chat window. If the check says the session expired, fetch it again and resubmit.
• One renewal channel at a time: do not keep auto-renewal on at OpenAI or the App Store at the same time, or you may be charged twice. Cancel where you subscribed.
• Unsure? Submit the data anyway: if the check fails, you pay nothing.

How to buy the Pro 100 top-up (6 steps)

1. Check your account’s plan: Sign in at chatgpt.com and open Settings → My Plan. Free, Plus and Pro 100 accounts can order the Pro 100 top-up straight away: on Free it is a new subscription, on Plus an upgrade, on Pro 100 a renewal. If the account is on an active Pro 200 or Pro 500, moving down is a downgrade, so ask the live chat before you order.
2. Turn off any duplicate auto-renewal: If the account renews automatically through chatgpt.com, the App Store or Google Play, switch that off where you subscribed first, or you may be charged twice.
3. Pick the product: On the pricing page choose ChatGPT Pro 100 as a top-up on your own account and check the price and stock.
4. Submit your session: Follow the order page: in the same browser, sign in to ChatGPT, open chatgpt.com/api/auth/session as the order page links it, select and copy all of the JSON, and paste it back into the order form. Paste it only there, never into a chat window.
5. Pay in USDT after the check: Your sign-in data is checked first; if the check fails you pay nothing. Then send exactly the USDT amount shown on TRC20 or BEP20; the amount identifies your order and payment is confirmed automatically.
6. Wait and verify: Delivery usually takes 5–30 minutes. The sign-in data is used once and cleared after delivery, and you keep your password. Confirm Pro 100 under Settings → My Plan.

Ready? ChatGPT Pro 100 top-up, 126.68 USDT. You will need a wallet or exchange that can send USDT on TRC20 or BEP20.

How to buy a ready-made Pro 100 account (5 steps)

1. On the pricing page choose ChatGPT Pro 100 as a ready-made account (133.98 USDT) and pay in USDT.
2. Enter a delivery email on the order page; Gmail or Outlook work best.
3. Click the verification email Cloudflare sends to it; check spam if it does not arrive. You can change a mistyped address on the order page, and a new address needs verifying again.
4. Our team delivers the account by hand after verification; the order page shows 30 minutes to about 4 hours.
5. Change the password first, then confirm Pro 100 under Settings → My Plan. Per the product description you can bind your own email.

After delivery: five checks

1. Plan: Settings → My Plan shows Pro 100.
2. Chat: GPT-6 Pro is in the model picker, and you can choose Extra High and Pro thinking. If GPT-6 itself is not in the model menu yet, the rollout may not have reached your account.
3. Usage: Settings → Usage shows your allowance and reset times (in the Codex app, Usage & Billing). Look here first whenever you hit a limit.
4. Codex: sign in to Codex on the web, CLI or IDE extension with the same account; there is no five-hour limit on Pro. For cloud tasks, see the Codex Cloud guide.
5. Billing: auto-renewal at chatgpt.com, the App Store or Google Play is off, and you have noted the end date.

Renewals: 30 days per order

• Reminders: emails 7, 3 and 1 day before the order ends.
• Top-up: place a new Pro 100 order on the same account at the then-current price; the sign-in data is checked again.
• Ready-made: message Telegram @ccnb1937 with your order ID and pay the Pro 100 top-up price, ¥850 ≈ 126.68 USDT, 7.31 USDT less than the first month.
• Month by month: Pro is monthly anyway, so you pick the tier again at each renewal. To move up from Pro 100, order the Pro 200 or Pro 500 top-up on the same account. To come back down, let the higher tier run out and then order Pro 100; ask the live chat first if you want to switch mid-period.

Is it legit? What is in writing, and what we cannot promise

What we guarantee in writing:

1. Checked before you pay. A top-up checks your sign-in data first, and you pay nothing if it fails; the data is used once and cleared after delivery.
2. One ready-made account, one buyer. Each ready-made account goes to a single buyer, and the order page shows its status at every step.
3. Refund terms are public. If an OpenAI regional policy change makes the service unavailable, you get a refund for the unused days, processed within 1 business day and returned in USDT. Contact the bottom-right live chat promptly if anything goes wrong.
4. So are the exclusions. Bans caused by breaking OpenAI’s usage policy are not refunded.
5. Track record. ClaudeMax has operated since November 2024 and has served more than 20,000 users (our own figure).
6. You can verify delivery yourself. Settings → My Plan shows Pro 100 on OpenAI’s own interface.

What we cannot promise:

• We are not OpenAI. ClaudeMax is independent: not OpenAI, and not an authorized OpenAI reseller.
• OpenAI sets the allowances. It decides how much each plan includes and when that changes, and it no longer publishes the weekly Pro-model count for Pro 100. At a limit you wait for the reset, use credits where they apply, or change tier.
• OpenAI’s Terms of Use. Sharing account credentials, reselling access and automatically extracting data are prohibited, and OpenAI may restrict access for misuse. We cannot change that; we can help you keep the risk low: one account, one person; change a ready-made account’s password at once; never lend or split it; avoid signing in from many different countries.
• Prices are not fixed forever, and ours can sit above OpenAI’s list price. They follow cost, exchange rate and stock; the pricing page is authoritative, and today’s gap to the list price is stated in the price box above.
