Plan prices, storage, Flow credits and Antigravity labels checked Oct 29, 2026 on Google One’s AI plans page and gemini.google/subscriptions. Antigravity quota wording comes from Antigravity’s plans docs (checked Oct 25, 2026) and models docs (checked Oct 26, 2026). Every source is listed at the bottom. No affiliate links on this page (how we work).

Quick answer

As of Oct 29, 2026 (US prices): Google AI Pro is $19.99 a month, or $199.99 a year. Google AI Ultra comes in two sizes. Ultra 5x is $99.99 a month and Ultra 20x is $199.99 a month, and Google says “Ultra plans are billed monthly only.”

What the extra $80 a month buys: 5x Pro’s Gemini usage limits, “Higher” Antigravity rate limits (Ultra 20x gets “Highest”), 10,000 Flow credits instead of 1,000, 20 TB of storage instead of 5 TB, full YouTube Premium instead of Lite, and Ultra-only extras like Project Genie.

For most developers, Pro is the right plan. Ultra makes sense once you hit Pro’s Antigravity weekly limit often enough that you’d be buying AI credits every week. Google doesn’t publish an AI credit price on its help pages, though, so nobody can tell you the exact break-even. The honest test is in the break-even section below.

Google AI Pro vs Ultra: price table

PlanPriceAI creditsStorage
AI Pro$19.99/mo or $199.99/yrBuy extra5 TB
AI Ultra 5x$99.99/moBuy extra20 TB
AI Ultra 20x$199.99/moBuy extra30 TB

US prices. Pro’s annual price shows in Google’s savings calculator as “Annual ($199.99)”. Ultra is “billed monthly only.” Storage per tier comes from Google One’s comparison table, and the Ultra card says “Cloud storage starting at 20 TB.” AI credits can be bought on Pro and Ultra only. Google lists increments of “2,500, 5,000, or 20,000 AI credits” and no price (Google One help, checked Oct 27, 2026). Neither plan page lists a monthly AI credit allowance. Sources: one.google.com and gemini.google, verified Oct 29, 2026.

Some arithmetic, ours not Google’s. Pro on annual billing works out to about $16.67 a month. Ultra 5x costs $80 a month more than monthly Pro, or $960 a year. Against annual Pro, it’s about $1,000 a year more. Ultra 20x is $180 a month more than monthly Pro.

What about “AI credits” in the brief’s sense? Here’s the catch. Ultra doesn’t come with a published pile of Antigravity credits. The 10,000 versus 1,000 number is Google Flow credits, which go to Google’s video and creative studio. In Antigravity, both Pro and Ultra cards say “Flexible AI credit pool”, meaning you can spend credits you’ve bought once you pass your limit. Paying for the bigger plan doesn’t get you more included Antigravity credits that Google will put a number on.

Antigravity limits on Pro vs Ultra

This is the section most readers came for, and Google answers it with adjectives.

  • Google One table, “Google Antigravity — Agent requests”: Pro “Expanded,” Ultra 5x “Higher,” Ultra 20x “Highest.”
  • gemini.google cards: Pro gets “Entry rate limits to agent model in Google Antigravity.” Ultra 5x gets “Higher rate limits,” and Ultra 20x gets “Highest rate limits.”
  • antigravity.google/pricing: Pro “More rate limits,” Ultra “Even more rate limits” (checked Oct 28, 2026).
  • Antigravity plans docs: Pro gets “A high, generous quota, refreshed every five hours until the weekly limit is reached” and “A higher weekly rate limit.” Ultra gets “The highest, most generous quota, refreshed every five hours” and “The highest weekly rate limits” (checked Oct 25, 2026).

So the clearest difference is the weekly ceiling. Both plans refill every five hours. Pro hits a weekly wall sooner, and Ultra’s wall is “the highest.” Google publishes no number for either, on any plan. Yes, “Expanded,” “Higher” and “Highest” are doing a lot of work for a company that runs on numbers. It’s the Lucky Strike pitch from Mad Men: “It’s toasted.” Everyone’s cigarettes are toasted.

Models are the same. Antigravity’s models docs list the same lineup for Pro and Ultra: Gemini 4 Argon plus Claude Sonnet 5.5 and Claude Opus 5.5. Claude and GPT models run on their own “Claude and GPT models” meter, and the two Claude 5.5 models are for non-trial Pro subscriptions only. Argon is “Not available in Antigravity IDE.” You get it in the Antigravity App, the CLI and IDE extensions. Ultra doesn’t add a model in Antigravity. It adds room.

At the limit. On both Pro and Ultra, an “AI Credit Overages” setting (Never or Always) decides whether Antigravity spends credits you’ve bought once your quota runs out. There’s no bring-your-own-key option. For the meters and resets in detail, see Antigravity usage limits. For the step below Pro, see Antigravity Plus vs Pro.

Gemini app limits, Veo and the rest

Outside Antigravity, Ultra is a bigger bundle, not a different product:

  • Gemini app usage: Pro gets “4x higher usage limits than Free.” Ultra gets 5x or 20x Pro: “up to 20x higher usage limits in Gemini than the Pro plan.” Both refresh “every 5 hours until you reach your weekly limit,” and AI credits can extend that.
  • Video: Pro’s FAQ mentions “a limited trial of Veo 3.1 Lite.” Ultra’s FAQ promises “the highest level of access” to “video generation with Veo 3.1.” Google One’s table lists Gemini Omni Flash for video generation on every tier, with more access on Ultra.
  • Deep Research and agents: Ultra gets “Higher access to Gemini 3.1 Pro, Deep Research, and Gemini Agent (US only, English only)” and “first access to advanced features like Tasks in Gemini (in select countries).”
  • Deep Think: not listed on either Google plan page on Oct 29, 2026, so we’re not claiming it for either tier.
  • Flow credits: 1,000 a month on Pro, 10,000 on Ultra 5x, 25,000 on Ultra 20x.
  • Developer extras: Google Cloud credits through the Google Developer Program are $10 a month on Pro, $40 on Ultra 5x and $100 on Ultra 20x. Jules task limits go from “Expanded” to “Higher” and “Highest.” Colab compute units go from 200 a month to 1,000 (Ultra 5x) or 2,000 (Ultra 20x), per the comparison table.
  • Bundle perks: YouTube Premium Lite on Pro, full YouTube Premium individual on Ultra (“available in over 40 countries”). Google Home Premium goes from Standard to Advanced. Project Genie is “Only available with a Google AI Ultra plan.”

If you were going to pay for YouTube Premium and a big storage plan anyway, Ultra’s real price drops in your head. Google’s savings calculator does exactly that math. It’s the Severance waffle party: the perks are real, and they’re still there to make the quota feel like a reward.

Break-even: when Ultra beats Pro plus top-ups

Here’s the honest version, using published prices only.

Step 1: the gap. Ultra 5x costs $80 a month more than monthly Pro. If you’re on annual Pro, it’s about $83.32 a month more, because Ultra is monthly only and you’d give up the annual discount.

Step 2: the alternative. Instead of upgrading, a Pro user who hits the weekly Antigravity wall can buy AI credits and set overages to “Always.” Credits are sold in packs of 2,500, 5,000 or 20,000, and they’re spent “based on standard API pricing for the specific model.”

Step 3: the comparison. If your credit top-ups regularly come to more than about $80 a month, Ultra 5x is cheaper, and you get the storage, Flow credits and YouTube on top. If they come to less, stay on Pro and top up. Ultra 20x needs top-ups of more than about $180 a month to beat Pro.

We can’t turn that into a number of agent runs, because Google doesn’t publish the dollar price of a credit pack on its help pages, or any Antigravity limit as a number. We’re not going to guess. Your checkout screen shows the credit price, so do the math there with real numbers.

The practical test: stay on Pro for two weeks with overages set to “Never.” Count how many times you hit the weekly limit and how many days you lost. If it’s most weeks, go to the checkout page and price a credit pack against $80. Upgrading to Ultra because Pro felt tight once is like moving into Gus’s superlab before you have the volume. Impressive gear, and a lot of rent.

One more angle. If you only need Ultra’s Antigravity room and don’t care about storage, video or YouTube, compare it with the Claude side too. Google AI Pro vs Claude Pro covers that, and AI coding tools compared puts Antigravity next to Cursor and the rest. For prices across every Google tier, see Gemini pricing and Antigravity pricing.

FAQ

Is Google AI Ultra worth it? Only if you regularly hit Pro’s weekly limits and would otherwise spend more than about $80 a month on AI credits, or you’d pay for 20 TB of storage and YouTube Premium anyway.

Google AI Pro vs Ultra Antigravity limits? Google labels Antigravity agent requests “Expanded” on Pro, “Higher” on Ultra 5x and “Highest” on Ultra 20x, with no published numbers, and Ultra gets “the highest weekly rate limits.”

Does Ultra include more AI credits? Ultra includes more Google Flow credits (10,000 or 25,000 a month vs 1,000 on Pro), but neither plan page lists an included Antigravity AI credit allowance, and extra credits are bought on both.

How much is Google AI Ultra? Ultra is $99.99 a month for 5x Pro’s limits or $199.99 a month for 20x, billed monthly only (US prices, checked Oct 29, 2026).

Is there an annual Google AI Pro price? Yes, Google’s savings calculator lists Google AI Pro at $199.99 a year; Ultra has no annual option.
