Google AI Ultra vs ChatGPT Pro: code on Pro, video on Ultra, and both $200 tiers buy 20x their $20 plan

At $200, Google AI Ultra and ChatGPT Pro both buy 20x their $20 plan

Of the five top tiers that Google and OpenAI sell, the $199.99 tier of Google AI Ultra and all three ChatGPT Pro tiers sell you usage in bulk. Google's plans page says Ultra 20x has "20x higher usage limits vs. AI Pro", and AI Pro is $19.99 on its own. So each AI Pro allowance in it costs you about $10. ChatGPT Pro at $200 stays at 20 times Plus in Codex and Work, because OpenAI canceled its planned cut to 10 times on 29 October 2026. That's $10 for each Plus allowance, half what Plus itself costs.

All three of the ChatGPT Pro tiers now charge you $10 for each Plus allowance. The $100 tier's standard allowance was five times Plus in Codex, per OpenAI's release notes of 9 April 2026. The $500 tier's was 25 times: OpenAI's DevDay recap says Pro 500 "offers our highest usage allowance at 25 times the ChatGPT Plus allowance." On 29 October 2026 OpenAI gave both "twice their previous Work and Codex allowance," so 10 and 50 times. Ultra at $99.99 breaks the pattern, at $20 for each of its five AI Pro allowances.

There's one caution with the squares. Each of them is a different $20 plan, so a square of Gemini isn't the same as a square of ChatGPT. OpenAI also keeps its multiples off the pages buyers read. The Pro tiers help article, the pricing page and the Codex page, read on 12 October 2026, give none for any Pro tier. The 20x for Pro 200 is in OpenAI's email to subscribers, which one of them posted on OpenAI's forum: usage "will decrease from 20 times to 10 times the ChatGPT Plus allowance." OpenAI canceled that decrease on 29 October 2026. Google prints both of its own on the plans page. And Pro isn't only more of the same: it adds GPT-6 Pro, a mode that Plus can't use in chat at all.

What does each Google AI Ultra and ChatGPT Pro tier include?

Google AI Ultra comes in two tiers and ChatGPT Pro comes in three. We built the table below from what each of the two vendors says on its own plan, help and pricing pages, as they read for a US account on 12 October 2026. Where a cell names a notice, release note or recap, OpenAI's plan pages don't give that figure.

Two of the rows decide most of the purchases. The first one is the clock. Google's limits page says that your limit "refreshes every 5 hours until you reach your weekly limit", and that's true on both of the Ultra tiers. OpenAI's Codex page says that "Pro plans currently have no five-hour limit." So a long day in Codex on Pro won't hit a wall at hour five. On Ultra, it can.

The second one is the model. That gap is bigger. OpenAI is also clear that Pro has a ceiling of its own. Its help article on GPT-6 says that "A Pro subscription does not include unlimited use of the GPT-6 Pro model." When you reach that limit on the $200 tier, ChatGPT switches you to GPT-5.6 Thinking at Medium until the limit resets.

Does Google AI Ultra or ChatGPT Pro have the better model?

ChatGPT Pro has the better model, and by a wide margin, as of October 2026. Its best one is GPT-6 Astra, which scores 53 on the Intelligence Index of Artificial Analysis and is 7th of the 227 models on it. Google's plans page lists two Gemini models for Ultra. The better of the two is Gemini Flash, which scores 41 and is 50th. Gemini Pro, which Deep Think needs, scores 30.

Deep Think isn't on the index. Google's limits page says that "Deep think (AI Ultra only) provides maximum parallel reasoning", and that an answer from it can take a few minutes. There's no independent score yet that sets it apart from plain Gemini Pro. It's the same story for GPT-6 Pro, which Artificial Analysis doesn't list either.

The gap may close before you renew, though. Google announced Gemini 4 Argon on 30 September 2026, and it scores 53 as well. Its post says that wider access will start "with paid API customers and Google AI Ultra subscribers", but it gives no date for it. As of 12 October 2026 it's only open to the cyber defenders in Google's Fairwind Program. If Argon is the reason you'd buy Ultra, check that it's on the plans page before you pay.

Is Google AI Ultra or ChatGPT Pro better for coding?

ChatGPT Pro is the better coding plan for most of the developers who ask. Codex runs Astra, which is the higher scoring of the two models, and none of the Pro plans has a five hour limit in it. On the $500 tier, Ultrafast generates up to 300 tokens a second in Codex, which OpenAI's DevDay recap puts at up to eight times the standard speed. But that speed costs you. OpenAI's article on the Pro tiers says that Ultrafast uses up your allowance at 8 times the normal rate, and that Fast mode uses it at 2.5 times.

Ultra's case is that it gives you more of Google's own tools. Google's post from 19 May 2026 gives the $100 plan "A 5X higher usage limit in the Gemini app and Google Antigravity than our Pro plan", and the $200 tier lifts that to 20 times. Gemini can also hold 1M tokens in a chat, which is more than the 400K that ChatGPT Pro allows, so a whole repository can fit in one Gemini thread. If you already work in Antigravity, buy Ultra. If you work in Codex or in a terminal, buy Pro.

Ultra wins video, storage and long files, and ChatGPT Pro wins images and research

Video is the cleanest split of all. Flow's credit page charges Ultra subscribers 10 credits for each Veo Fast clip, which is half of the 20 that everyone else pays. So the 10,000 credits that come with Ultra each month make 1,000 Fast clips, and the 25,000 on the top tier make 2,500. OpenAI sells no video. Its Sora page says that "As of April 26, 2026, the Sora product is no longer available." And Flow credits don't roll over, so a quiet month on Ultra still costs you $99.99.

Research is closer. OpenAI lists "Maximum deep research" on Pro, and the ChatGPT deep research limit explains how that allowance is counted. Ultra has Deep Research too, but Google doesn't say how many reports you get. All that its limits page says is that "Some features (like media generation or Deep Research) will consume more of your usage."

Who should buy neither plan?

You don't need either one if you haven't hit the wall on a $20 plan. Google's limits page gives AI Pro, at $19.99, the same 1M tokens of context as Ultra. And OpenAI's help center says that "Plus plans include GPT-6 Astra in ChatGPT Work and Codex." Google AI Pro vs ChatGPT Plus compares the two plans at that level. Is Google AI Ultra worth it works out the cost of Ultra's video clip by clip, and ChatGPT Plus vs Pro covers the step up on OpenAI's side.

You also don't need either if what you want is Gemini and GPT on one bill, rather than more of one of them. Whizi Powerhouse is $49.99 a month for 10,000 credits as of October 2026. On it, an Astra message costs 100 credits and a Gemini Pro one costs 10, so that's 100 of the Astra answers or 1,000 of the Gemini ones. Whizi Pro is $29.99 for 2,500 credits, and it has Gemini Pro and ChatGPT Sol from 10 credits each, side by side in the same chat. Whizi loses on the heavy rows. It has no Veo, no Codex, no Deep Think and no storage, and it caps the input of each message at 40,000 tokens, where Gemini takes 1M. Gemini in Whizi and how credits work list all of the rates.
