The short version: From October 30, ChatGPT Pro 200 still costs $200 a month but carries half the ChatGPT Work and Codex allowance it had: 10 times the $20 Plus plan instead of 20 times, according to OpenAI’s figures as reported by Engadget and The Next Web. The new Pro 500 costs $500 for 25 times Plus. Do the division and every step of OpenAI’s ladder now costs the same $20 per multiple of Plus. Anthropic’s $200 Claude Max plan still buys 20 times its $20 Pro plan, which works out to $10 per multiple. The bulk discount at $200 now exists at one company and not the other.
OpenAI announced the change at DevDay on September 29, alongside Dots, its always-on agents, and GPT-6.1 Sol, a new mid-tier model. The day before, Anthropic released Claude Sonnet 5.5. The two models landed at the same API price. The two $200 plans did not land in the same place.
What changes on ChatGPT Pro 200 on October 30?
OpenAI’s Pro help page, read on September 29, says new Pro 200 subscriptions now come with “a lower usage allowance than previously offered.” Anyone whose Pro 200 was active at the eligibility cutoff, or in the seven days before it, keeps the old allowance through October 29, 2026. After that, the plan moves to the lower allowance and the price stays at $200.
The reported numbers, from The Next Web and Engadget: Work and Codex usage falls from 20 times Plus to 10 times, and weekly GPT-6 Pro chat messages fall from 200 to 100. Existing subscribers get a one-time credit grant that OpenAI values at $2,500, which expires at the end of 2026. Everyday chat on Pro stays unlimited, subject to OpenAI’s abuse guardrails.
Two more lines from the help page matter if you are deciding what to do. Pro is billed monthly only, with no annual option. And buying extra credits on Pro 100 or Pro 200 does not unlock Ultrafast, the fastest version of GPT-6 Astra; only Pro 500 includes it.
ChatGPT Pro vs Claude Max: what does each dollar buy?
Both companies sell a $20 plan and measure their bigger plans as multiples of it. OpenAI’s DevDay recap puts Pro 500 at 25 times the Plus allowance. Anthropic’s Max plan page lists Max 5x at $100 and Max 20x at $200, measured against Claude Pro.
| Plan | Monthly price | Usage vs $20 plan | Price per multiple | Note |
|---|---|---|---|---|
| ChatGPT Plus | $20 | 1x | $20 | Baseline |
| ChatGPT Pro 200, to Oct 29 | $200 | 20x | $10 | Existing subscribers only |
| ChatGPT Pro 200, from Oct 30 | $200 | 10x | $20 | Work and Codex |
| ChatGPT Pro 500 | $500 | 25x | $20 | Only plan with Ultrafast |
| Claude Pro | $20 | 1x | $20 | $17 a month billed annually |
| Claude Max 5x | $100 | 5x | $20 | Per five-hour session |
| Claude Max 20x | $200 | 20x | $10 | Per five-hour session |
Read the price-per-multiple column, not the totals. Until October 29, both $200 plans sold usage at half the rate of their $20 plans. From October 30, OpenAI charges $20 per multiple at every tier with a figure on record, so paying more buys more but no longer buys it cheaper. Anthropic’s top tier keeps the discount. OpenAI does not publish a multiple for Pro 100.
One caution the table cannot fix: “10 times Plus” and “20 times Claude Pro” are not the same amount of work, because a Plus allowance and a Claude Pro allowance are different sizes, measured differently, and neither company publishes a fixed message count. The table compares how each company prices its own ladder. It does not prove that Claude Max 20x does twice the work of ChatGPT Pro 200.
Is GPT-6.1 Sol cheaper than Claude Sonnet 5.5?
On list price, they are the same. OpenAI’s launch post prices GPT-6.1 Sol at $2 per million input tokens and $10 per million output tokens. Claude Sonnet 5.5, released the day before, is $2 and $10 on Anthropic’s model page. The one difference is reused context: cached input costs $0.10 per million on GPT-6.1 Sol against a $0.20 cache read on Sonnet 5.5, which matters mostly to the software vendors building on these models.
Inside ChatGPT, extra usage is bought in credits, and OpenAI’s rate card charges 50 credits per million input tokens and 250 per million output tokens for GPT-6.1 Sol. At the value OpenAI put on its grant to existing subscribers, 62,500 credits for $2,500 as reported by The New Stack, a credit is worth four cents, which makes those rates $2 and $10. That is the API price, and the same as Sonnet 5.5’s. Claude’s paid plans work the same way at the ceiling: its pricing page says that when you hit a limit you can keep working with usage credits at standard API rates.
Where the two differ is access. GPT-6.1 Sol runs in ChatGPT Work and Codex on paid plans and is not yet in regular chat. Sonnet 5.5 is the model on Claude’s free plan, as we covered in what the free Claude now does.
What should a small business on Pro 200 do before October 30?
Most owners are on a $20 plan or a team plan, and nothing here changes their bill. The owner this touches is the one running daily automations or coding work through Codex or ChatGPT Work on Pro 200. For that person, the decision is mechanical:
Check your usage first. OpenAI’s help pages point to Settings, then Usage, in ChatGPT. If you have been using less than half your Work and Codex allowance, the cut changes nothing you will notice.
If you use more than half, you have three routes: keep Pro 200 and buy credits after the allowance runs out; move to Pro 500, which costs $300 more for two and a half times the new Pro 200 allowance plus Ultrafast; or test the same work on Claude Max 20x at $200 before your renewal. The credit grant does not expire until December 31, so you have until then to measure which route your actual workload needs.
If you mainly want Dots, note that OpenAI’s pricing page lists the dot under Pro from $100, and OpenAI says dots are rolling out across Pro, Business Premium and Enterprise plans in eligible markets. You do not need Pro 200 to get one.
The price did not change. What changed is that the discount for buying in bulk at $200 went away at OpenAI and stayed at Anthropic, and for the owner who lives in Codex all day, that is worth an afternoon with the usage dashboard. For the earlier round of this price race, see Opus 5.5 vs GPT-6 Sol.
Frequently Asked Questions
When does the ChatGPT Pro 200 usage cut take effect?
October 30, 2026. Subscribers whose Pro 200 plan was active at OpenAI’s eligibility cutoff, or in the seven days before it, keep the previous allowance through October 29. New Pro 200 subscriptions get the lower allowance now, and the price stays at $200 a month.
How much usage does ChatGPT Pro 500 include?
OpenAI says Pro 500 offers 25 times the ChatGPT Plus allowance for $500 a month, the highest of its plans, and it is the only Pro plan that includes Ultrafast, the fastest version of GPT-6 Astra.
Is Claude Max cheaper than ChatGPT Pro?
Per multiple of the $20 plan, Claude Max 20x is cheaper at $10 against $20 for ChatGPT Pro 200 after October 30. The two base plans are different sizes and neither company publishes a fixed message count, so the only reliable test is running your own workload on both.
Do you need ChatGPT Pro 200 to get Dots?
No. OpenAI’s pricing page lists the dot as part of Pro starting at $100 a month, and OpenAI says dots are rolling out across Pro, Business Premium and Enterprise plans in eligible markets.

GPT-6.1 Terra Pricing: The 30-Minute Cache Clock
October 27, 2026 @ 7:44 pm
[…] The larger story here is good news. A model that OpenAI says keeps pace with its premium tier on one benchmark of professional tasks now costs a dollar per million tokens going in, and the arithmetic for a real small business assistant lands under $10 a month on the right setting. The fine print simply moved from the price to the settings, and the settings are a conversation an owner can have. For more on how plan pricing is moving at the subscription level, see our look at ChatGPT Pro 200 against Claude Max. […]
