GPT-6 and Intelligent UI in ChatGPT (October 2026): what Free, Go, Plus and Pro each get, and which Pro tier to buy

What changed on October 7

• When. OpenAI published its announcement, titled GPT-6 and Intelligent UI for everyone, on October 7. The rollout started globally that day in the Chat tab for Plus, Pro, Business and Enterprise, and expanded to Free and Go from October 8. Enterprise availability depends on workspace admin settings.
• Which model. Paid plans run GPT-6 Sol; Free and Go run GPT-6 Luna. OpenAI says both are tuned for everyday conversation. The Pro thinking level is unchanged: it is still GPT-6 Pro, powered by GPT-6 Astra.
• The model menu. GPT-6 replaces Latest. If you had Latest selected, you move to GPT-6 at the same thinking level; an explicit GPT-5.6 Sol selection stays where it is. The menu says just GPT-6; it is not labelled Sol.
• Gradual. Per the Help Center, if you do not see GPT-6 in the model menu, it may not be available for your account yet.
• Scale. OpenAI puts ChatGPT at more than 1.2 billion weekly users (its own figure).

One point where OpenAI’s own pages disagree. The announcement and the October 7 release note both say Free and Go use GPT-6 Luna, and the Free card on the pricing page lists unlimited text chats with GPT-6. The Help Center’s model page, as of October 10, still says Free and Go users receive GPT-5.6 Luna and names only paid plans in the rollout. The rollout is still in progress, so we report both: trust your own model menu. If it shows GPT-6, you have it.

What Intelligent UI is, and where it works

Intelligent UI is the new way GPT-6 answers in chat. Instead of one block of text, a reply can combine text, visuals and interactive elements, and the model chooses the layout to fit the question. OpenAI’s examples: a comparison laid out side by side; an interactive diagram where you change an input and watch the result; or a small tool built on the spot, such as a savings calculator, a bill splitter for a dinner, or a game you can play in the conversation. When plain text is the best answer you still get plain text, and you do not need a special prompt.

The second change is answering while thinking. With reasoning models you used to wait for the thinking to finish; GPT-6 can start with what it has and add findings as it goes.

OpenAI gives two speed figures, both from its own internal evaluations, not independent tests: on questions that need web search, GPT-6 Instant starts answering 44% sooner on average than GPT-5.6 Instant, and GPT-6 Extra High begins answering in about the time GPT-5.6 Medium took. Your own account is the real test.

What Free, Go, Plus and Pro each get (checked 2026-10-10)

Three notes on reading it. First, the Free / Go cell follows the announcement; the Help Center says otherwise, as explained above. Second, the Help Center sentence on GPT-6 Pro names Pro $100, Pro $200, Business and Enterprise; for Pro 500 we rely on the pricing page, where one Pro card covers all three tiers and lists Pro reasoning powered by GPT-6 Astra. Third, OpenAI no longer publishes GPT-6 Pro message counts per tier; it says only that Pro plans with higher allowances get higher Pro-model limits, and ChatGPT shows the reset time when you run out. Beyond chat, the Pro card also lists a Dot, the always-on agent (rolling out to eligible Pro users aged 18 and older, not in the EEA, Switzerland or the UK at launch), unlimited and faster image creation, and maximum deep research.

What did not change

• Work and Codex models. The update applies to chat only; OpenAI says the models powering Work and Codex are not changing with this release. For those, see GPT-6 Sol and Luna in Codex and Work.
• Older models are not retired by this. A chat with GPT-5.6 Sol explicitly selected stays on GPT-5.6, and GPT-5.6 Sol Pro remains the Pro option in that family.
• GPT-5.5 is a separate matter. It was retired from ChatGPT, Work and Codex on October 14 (the API is not affected), on its own schedule.
• Limits and allowances. Intelligent UI has no quota of its own, and thinking and Pro-model limits work as before. When you hit one, ChatGPT shows the reset time; Support cannot reset limits.
• Instant does not escalate by itself. On Plus and Pro, Instant stays Instant; asking it to think harder does not switch levels. Pick the level on the Thinking slider.
• Pro 200’s allowance change on October 30 is unrelated. That is about grandfathered Pro 200 subscriptions moving to the new allowance; see Pro 200 changes on October 30.

Free has GPT-6 now. Do I still need to pay?

The short answer: if all you wanted was GPT-6 and Intelligent UI, you no longer need to pay. Free has both, and OpenAI describes everyday text chats on Free and Go as unlimited, subject to abuse safeguards; file uploads, image generation, voice and data analysis keep their own limits. What a paid plan buys is not the GPT-6 name but three things: the stronger model (GPT-6 Sol instead of GPT-6 Luna), thinking levels you choose yourself, and the working tools and allowances: Codex, ChatGPT Work and deep research.

Do not buy when:

• Intelligent UI is the only reason. Free has it. And the higher you go, there is one place it is missing: the Pro thinking level does not support it.
• You only overflow in Codex now and then. Buy Codex credits first (500 credits ≈ 26.83 USDT) rather than a higher tier. Credits work in Codex and ChatGPT Work; they do not add GPT-6 Pro messages in chat.
• You plan to split one Pro account between several people. Don’t. OpenAI’s terms prohibit sharing credentials and reselling access, and shared use is how accounts get restricted.

If the real reason you are still on Free is that chatgpt.com declines your card or does not serve your country, that is the part we solve: you pay in USDT and the plan lands on your own account. See Card declined or country unsupported and the step-by-step USDT payment guide.

Pro 100, 200 or 500: what one unit of usage costs

The three tiers share the same chat model and features; they differ in allowance and speed. On allowance, the Help Center says only that Pro 200 includes more usage 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, not official figures) 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 on Pro 100 costs about 25.34 USDT against 27.58 USDT on Plus, so if Plus runs out most days, Pro 100 is the better deal. Pro 200 costs 1.53x as much as Pro 100 for about 2x the usage (reported), so each unit is cheaper on Pro 200: 19.38 USDT against 25.34 USDT. At today’s prices the cheapest unit on our list is Pro 200 (new allowance), about 19.38 USDT. The multiples are rough ratios for Codex and Work; GPT-6 Pro in chat is counted separately, and Settings → Usage is the authority for your own account.

Against OpenAI’s list price. Taking 1 USDT ≈ 1 USD, and before any foreign-card fees or taxes on OpenAI’s side: Pro 100 is 126.68 USDT here, 26.68 USDT more than OpenAI’s $100; Pro 200 is 193.75 USDT here, 6.25 USDT less than OpenAI’s $200; Pro 500 is 536.37 USDT here, 36.37 USDT more than OpenAI’s $500. Where we cost more, the difference pays for convenience: no card that chatgpt.com has to accept, payment in USDT, and a check before you pay.

Also new for paying users this week

• Composer predictions in Codex (October 9, beta). After Codex replies, a suggested next message may appear in the message box; press Tab to accept it, and it is not sent automatically. It is open to personal Pro users aged 18 and older in the latest Codex desktop app, for local and SSH threads using GPT-6 Astra or GPT-6.1 Sol. During the beta, generating predictions does not count toward Codex limits or consume credits; the messages you send are billed as usual.
• Audio uploads (October 6). On paid subscriptions you can upload audio files to get a transcript, a summary or answers about the recording, for example turning a meeting or lecture into notes. Availability varies by region, client version and model, and transcripts may contain errors.

Check what your account has, then upgrade in place (6 steps)

1. Update the app, or use the web: Intelligent UI works on the web and in updated mobile apps; the older macOS and Windows desktop apps do not support it. Update the mobile app to the latest version, or open chatgpt.com.
2. Look for GPT-6 in the model menu: Open the model menu and look for GPT-6. It replaces Latest and is not labelled Sol. If it is missing, the rollout may not have reached your account yet; check again in a few days.
3. Check your thinking levels: With GPT-6 selected, open the Thinking slider. Free and Go have no Medium or High, only Think; Plus has Medium and High; Pro adds Extra High and Pro. That is what your plan actually gets in chat.
4. Confirm your plan and switch off duplicate auto-renewal: Open Settings → My Plan to see whether you are on Free, Plus or Pro. If you plan to upgrade through us and 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.
5. Pick a tier and submit your session: On the pricing page choose Pro 100, Pro 200 or Pro 500 as a top-up on your own account (Free, Plus and Pro accounts all qualify). In the same browser, sign in to ChatGPT, open chatgpt.com/api/auth/session as the order page links it, copy all of the JSON and paste it into the order form. Paste it only there, never into a chat window.
6. Pay after the check, then verify: 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. Delivery usually takes 5–30 minutes. Confirm the tier under Settings → My Plan, then reopen the model menu and the Thinking slider: on Pro you should see Extra High and Pro.

Not sure about your account’s state? Submit the data anyway: if the check fails, you pay nothing. If you subscribed through the App Store or Google Play, or the account is on Go or another state, ask the live chat before ordering. New to USDT? You will need a wallet or exchange that can send USDT on TRC20 or BEP20.

Buying here: top-up on your own account, or ready-made

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. Each order covers 30 days, and Pro is monthly-only at OpenAI. Do not keep auto-renewal on at OpenAI or the App Store at the same time, or you may be charged twice.

What we guarantee, 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 your Pro tier 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 controls the rollout and the allowances. When GPT-6 and Intelligent UI reach a given account, how much each plan includes and whether that changes again are OpenAI’s decisions; upgrading does not bring the rollout forward.
• 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. They follow cost, exchange rate and stock; the pricing page is authoritative.
