ChatGPT Pro 500 is here. What changes for the $200 Pro plan?

At DevDay on September 29, OpenAI announced Pro 500, a new top ChatGPT plan. For $500 a month it includes 25 times the Plus allowance and Ultrafast, OpenAI’s quickest speed setting.

The $200 Pro plan changed the same day. It is open to new subscribers again, but with a smaller allowance than before, and current subscribers keep their limits only through October 29. OpenAI also added a way to sign in to other apps with your ChatGPT account and let them draw on your plan.

If you pay for Pro today, or are thinking about it, here is what changed and when.

At a glance

Pro 200	$200	20x, going to 10x	no	1

• Pro 500’s 25x and Ultrafast come from OpenAI’s announcement.
• Pro 100’s 5x is from OpenAI’s earlier help text; Pro 200’s 20x and 10x are as reported by The New Stack and Engadget. The current help page lists no multiples.
• Dots are the always-on agents launched the same day. Every Pro tier includes one. For Pro users they are rolling out everywhere except the European Economic Area, Switzerland and the UK.

What Pro 500 includes

Allowance. OpenAI says Pro 500 includes 25 times the Plus allowance, the most of the three Pro plans.

Ultrafast. A premium speed tier for work where speed matters most. In Codex it makes token generation up to 8 times faster, reaching 300 tokens per second; in the API, up to 6 times faster. It is available for GPT-6 Astra today, with a GPT-6.1 Sol version coming soon.

Among Pro plans only Pro 500 has Ultrafast, which you select in the model picker. It draws on your included allowance first and then on credits. At launch, buying credits on Pro 100 or Pro 200 does not unlock it.

Computer-use agents. The Agents API, which now supports computer use, is available through the API and in Codex and ChatGPT Work on Pro 500 and Enterprise.

Pro is billed monthly only. There is no annual option.

What changes for the $200 Pro plan

New subscribers. Pro 200 sign-ups are open again at the same $200 price. Unite.AI reports they had been paused since September 10. New subscriptions come with a lower allowance than before, which OpenAI says reflects its increasingly efficient models.

Current subscribers. If your Pro 200 subscription was active at the eligibility cutoff, or lapsed in the seven days before it, you keep your current allowance through October 29. After that you move to the lower allowance, and affected users get an email. Keeping the allowance does not turn the plan into Pro 500 or add Ultrafast.

How big a cut. OpenAI’s help page gives no numbers. The New Stack and Engadget report that from October 30 the Codex and ChatGPT Work allowance drops from 20 times Plus to 10 times, and GPT-6 Pro messages in chat drop from 200 a week to 100.

Compensation. Engadget reports a one-time credit for current subscribers. The New Stack, citing OpenAI, puts it at 62,500 usage credits, worth $2,500, expiring on December 31, 2026.

OpenAI’s reasoning. Thibault Sottiaux (Tibo), who works on Codex and ChatGPT at OpenAI, wrote on X that the new calculation nets out at half the API-spend value of the old Pro 200. In return, OpenAI will not bring back the five-hour limit, so you can use your weekly allowance whenever you like, and he argued that more efficient models mean subscribers still get more done than on Pro 200 a month ago.

The reception was cool. The New Stack’s subhead reads “Developers aren’t happy,” and Engadget’s headline says OpenAI nerfed its existing $200 tier.

The allowance per dollar

Divide the published and reported multiples by price and a pattern appears. Plus is 1x for $20, Pro 100 is 5x for $100, the new Pro 200 is 10x for $200, and Pro 500 is 25x for $500. All four plans now buy the same allowance per dollar.

The old Pro 200 bought twice as much for the same money. Current Pro 200 subscribers are the ones who feel this change most.

Using your ChatGPT plan in other apps

Sign in with ChatGPT lets you sign in to other apps and sites with your ChatGPT account. Plus and Pro subscribers can go a step further and let the app run its AI requests on their ChatGPT plan, with no OpenAI API key to create or share.

• Where it works. OpenAI says it launches with 16 partners. The help article names the open-source tools OpenCode, OpenClaw, Pi by Earendil and T3, and the commercial tools Devin, Notion, Vercel, Warp, Amp, Dactyl, Kilo Code, Conductor, Hyperagent, Hermes Agent and Vorflux. Airtable, Canva, GitLab, HubSpot and Supabase support the sign-in only, not plan sharing.
• What it uses. The app’s AI requests count toward the ChatGPT Work and Codex allowance in your plan.
• Per-app limits. In Settings > Usage you can set a weekly limit for each app. It caps the share of your overall weekly allowance that app may use; it does not reserve a separate pool.
• Credits. For an app to keep going on credits after you hit your plan limits, you have to allow it. The option is off by default and needs the app’s limit at 100%. If automatic credit purchases are on, usage can keep costing money, so check that first.
• What is shared. The app receives your name, email and profile picture. Your conversations, memories and any API key are not shared.
• Disconnecting. Signing out of the app leaves the connection in place. Disconnect it under Settings > Security and login > Login connections; usage already recorded is not refunded.

OpenAI Marketplace for enterprises

Enterprise customers will be able to put part of their existing OpenAI commitment toward approved partner software. The first 32 partners include Adobe, Figma, Salesforce, ServiceNow, HubSpot, Harvey, CrowdStrike, Palo Alto Networks and Baseten for open-model inference. For now, companies can register interest.

Which plan fits

• Occasional Codex or Work use: Plus is enough, though it does not include Dots.
• You want to try Dots: start at Pro 100. Every Pro tier includes one, and conversations with it don’t count toward your usage.
• Long Codex runs every day: you are choosing between Pro 200 and Pro 500. The allowance per dollar is the same, so the difference is the size of the allowance and Ultrafast.
• Response speed sets your pace: look at Pro 500 for Ultrafast, and if you build software, compare Ultrafast in the API too.
• Current Pro 200 subscribers: nothing changes until October 29. Use the email and your usage screen to judge whether the post-October 30 allowance covers your workload.

What to keep in mind

• The only multiple OpenAI stated in this announcement is Pro 500’s 25x. The Pro 100 and Pro 200 figures come from earlier help text and press reports, so check the pricing page and your usage screen before you subscribe.
• Conversations with your dot don’t count toward usage. The help article says dots usage won’t count toward plan allowances for the first month, with plan-specific terms to follow; the announcement says tasks your dot starts in Codex or Work count as usual.
• The help article does not say whether Ultrafast uses up your allowance faster.
• All prices are monthly and in US dollars.
