Google AI Pro vs Google AI Ultra: Complete Comparison and Report on Price, Usage Limits, Gemini 4 Carbon Access, and Flow Credits
Google AI Pro and Google AI Ultra are the two upper tiers of Google's consumer AI subscription, sold through Google One and the Gemini app. Google AI Pro costs $19.99 a month in the United States, or $199.99 a year, and includes Gemini 4 Argon, a 1M-token context window in the Gemini app and 5 TB of storage. Google AI Ultra has existed in two versions since Google I/O on May 19, 2026, when Google added a $99.99 Ultra plan with 5x the usage of Pro and cut the original Ultra plan from $249.99 to $199.99 a month with 20x the usage of Pro. Both Ultra versions are billed monthly only, according to the Google One plans page.
The deciding facts are few and concrete. Ultra is the only consumer plan that includes Gemini 4 Carbon, Google's strongest model, in the Gemini app, Tasks, AI Mode in Search and Google Antigravity, which Google began rolling out to all Ultra subscribers on November 10, 2026. Pro keeps Gemini 4 Argon, Gemini 4 Hydrogen and the older Gemini Pro model, and both plans share the same 1M-token context window, the same thinking levels and the same app features such as Deep Research, Canvas, scheduled actions and Tasks. The rest of the gap is volume: 5x or 20x the Pro usage allowance, 10,000 or 25,000 Google Flow credits a month instead of 1,000, 20 TB or 30 TB of storage instead of 5 TB, and a full YouTube Premium individual plan instead of YouTube Premium Lite.
The choice follows from those numbers. Pro is the better plan for a person who wants Argon every day and hits limits only occasionally, especially on annual billing at an effective $16.67 a month. The $99.99 Ultra plan fits heavy daily users who need Carbon or keep running out of Pro allowance, and it costs the same per unit of usage as monthly Pro. The $199.99 Ultra plan is the cheapest way to buy Google AI usage at scale, because it delivers 20x the Pro allowance for 10x the Pro price, and it is the plan Google ties to Project Genie and to free lower-priority Veo 3.1 Lite generations in Flow. Prices and plan terms were verified on Google's official pages on November 14, 2026.

GOOGLE AI PRO AND GOOGLE AI ULTRA: RELEASE TIMELINE AND PLAN IDENTITY.
Google AI Pro took its name on May 20, 2025, when Google renamed its existing AI Premium plan, and it sits above Google AI Plus ($4.99 a month) and below Ultra in the Google One lineup. Its model access changed most recently on October 13, 2026, when Gemini 4 Argon started rolling out globally to Pro and Ultra subscribers in the Gemini app. Since then Argon has been the top model a Pro subscriber can select in chats and in Tasks.
Google AI Ultra launched in the United States on May 20, 2025 as a single $249.99 monthly plan. The I/O 2026 announcement of May 19, 2026 reshaped it into two plans that Google's own pages label in different ways: the help center and the Gemini subscriptions page call them Ultra with "5x" and "20x" usage, while the Google Flow help center labels them "Google AI Ultra $100" and "Google AI Ultra $200". The $99.99 plan was presented as the option for developers, technical leads, knowledge workers and advanced creators, and the $199.99 plan kept the capabilities of the old $249.99 plan at a lower price.
The newest difference between the tiers arrived on November 10, 2026, when Google announced that Gemini 4 Carbon was rolling out to all Google AI Ultra subscribers in Google Antigravity, the Gemini app and AI Mode in Search. The same announcement opened Carbon to paying API developers at an introductory $2 per 1M input tokens and $10 per 1M output tokens until November 30, 2026, rising to $4 and $20 afterwards, but no consumer tier below Ultra received it.
........
Date | Event | Plans affected |
May 19, 2026 | $99.99 Ultra plan (5x Pro usage) added; top Ultra plan cut from $249.99 to $199.99 (20x Pro usage) | Ultra |
May 19, 2026 | Compute-based limits replace daily prompt limits in the Gemini app, refreshing every 5 hours up to a weekly cap | Plus, Pro, Ultra |
May 19, 2026 | YouTube Premium Lite announced for Pro; YouTube Premium individual for both Ultra plans | Pro, Ultra |
October 13, 2026 | Gemini 4 Argon rolls out globally in the Gemini app | Pro, Ultra |
November 10, 2026 | Gemini 4 Carbon rolls out in the Gemini app, AI Mode and Antigravity | Ultra only |
December 5, 2026 | Omni Flash 1.1, Veo 3.1 Fast and Veo 3.1 Quality scheduled to retire in Google Flow | Plus, Pro, Ultra |

GOOGLE AI PRO VS ULTRA PRICING: MONTHLY, ANNUAL AND PER UNIT OF USAGE.
Google AI Pro is the only one of the three plans with an annual option. The Google One plans page lists Pro at $19.99 a month or $199.99 a year, while both Ultra plans appear as monthly subscriptions with no annual price. Over twelve months, monthly Pro costs $239.88, annual Pro costs $199.99 (a saving of $39.89), the $99.99 Ultra plan costs $1,199.88 and the $199.99 Ultra plan costs $2,399.88.
The usage multipliers allow a direct price-per-allowance comparison, because Google defines Ultra's allowance relative to Pro and Pro's allowance relative to accounts without a plan. Pro gives 4x the standard usage of a free account, so the $99.99 Ultra plan amounts to 20x the free allowance and the $199.99 plan to 80x. The arithmetic below divides each monthly price by its allowance expressed in "Pro units".
........
Plan | Monthly price (US) | Annual price | Cost over 12 months | Usage vs free account | Price per Pro-sized allowance |
Google AI Pro, monthly | $19.99 | n/a | $239.88 | 4x | $19.99 |
Google AI Pro, annual | $16.67 effective | $199.99 | $199.99 | 4x | $16.67 |
Google AI Ultra 5x | $99.99 | Not offered | $1,199.88 | 20x | $20.00 |
Google AI Ultra 20x | $199.99 | Not offered | $2,399.88 | 80x | $10.00 |
........
The result is a pricing curve with one cheap step. The $99.99 Ultra plan charges 5.0 times the monthly Pro price for 5 times the allowance, so its usage costs the same as monthly Pro and about 20% more than annual Pro. The $199.99 plan charges 10.0 times the Pro price for 20 times the allowance, halving the cost of each unit of usage. A subscriber who would otherwise exhaust the $99.99 plan every week pays $100 more a month for four times the room, the steepest volume discount in Google's consumer lineup.

USAGE LIMITS IN THE GEMINI APP: HOW THE 5-HOUR AND WEEKLY CAPS WORK ON PRO AND ULTRA.
Since May 2026 the Gemini app no longer counts prompts per day for subscribers. Google's limits page describes compute-based limits that account for prompt complexity, features used and chat length, refresh every five hours and stop at a weekly limit. Media generation and Deep Research consume more of the allowance, and so do higher-tier models and higher thinking levels. When a paid subscriber reaches the limit, chats continue on Gemini Flash-Lite.
Google publishes multipliers and no absolute prompt counts. The limits page lists standard limits and a 32K-token context window without a plan, 2x the standard limits and 128K tokens on Plus, 4x and 1M tokens on Pro, and "5x or 20x higher than AI Pro" with 1M tokens on Ultra. The context window is therefore identical on Pro and both Ultra plans, and the difference is how long a subscriber can work with the largest models before falling back to Flash-Lite.
........
Limit | No plan | Google AI Plus | Google AI Pro | Google AI Ultra 5x | Google AI Ultra 20x |
Usage allowance | Standard | 2x standard | 4x standard | 5x Pro | 20x Pro |
Context window in the Gemini app | 32K tokens | 128K tokens | 1M tokens | 1M tokens | 1M tokens |
Refresh cycle | Standard | Every 5 hours up to a weekly limit | Every 5 hours up to a weekly limit | Every 5 hours up to a weekly limit | Every 5 hours up to a weekly limit |
Fallback after the limit | n/a | Flash-Lite | Flash-Lite | Flash-Lite | Flash-Lite |
Antigravity quota | Weekly quota | Weekly quota | Refreshed every 5 hours up to a weekly limit | Highest quota, 5x Pro | Highest quota, 20x Pro |
Paid AI credit top-ups | No | No | Yes (Flow, Antigravity) | Yes (Flow, Antigravity) | Yes (Flow, Antigravity) |
........
AI credits extend usage beyond the plan allowance and are sold only to Pro and Ultra subscribers, outside Japan. Google's AI credits help page mentions packs of 2,500, 5,000 or 20,000 credits, names Google Flow and Google Antigravity as the products where they apply, and does not list prices on the page. Credits are deducted at standard API pricing for the model and request complexity, according to the Pro and Ultra benefit pages. At I/O Google described top-up credits for the Gemini app as "coming soon", and the current help pages still do not list the Gemini app among the products that accept them.
··········
GEMINI MODELS ON GOOGLE AI PRO AND ULTRA: ARGON, CARBON, HYDROGEN AND THINKING LEVELS.
The model picker is where the two plans differ in kind. Google's "About Gemini models" help page lists the models in chats and in Tasks for each plan. Pro subscribers can choose Flash-Lite, Gemini 4 Hydrogen, Gemini Pro and Gemini 4 Argon in chats, and Hydrogen or Argon in Tasks. Ultra subscribers get Flash-Lite, Hydrogen, Argon and Gemini 4 Carbon in chats, and Hydrogen, Argon or Carbon in Tasks. All paid plans offer the same three thinking levels (Low, Medium and High), with Low as the default when none is selected.
........
Model or setting | Google AI Pro | Google AI Ultra (5x and 20x) | Google's description |
Gemini 4 Carbon | No | Chats and Tasks | Strongest model, for the hardest long-running problems |
Gemini 4 Argon | Chats and Tasks | Chats and Tasks | Top-tier intelligence and deep reasoning |
Gemini Pro | Chats | Not listed in the picker | Advanced reasoning for complex prompts and coding |
Gemini 4 Hydrogen | Chats and Tasks | Chats and Tasks | Fast and capable for chat and tasks |
Gemini Flash-Lite | Chats | Chats | Fast, cost-efficient, used after limits |
Thinking levels | Low, Medium, High | Low, Medium, High | Higher levels use more allowance |
Carbon in AI Mode in Search | No | Yes, select countries | Highest access to Carbon in Search |
Carbon in Google Antigravity | No | Yes | Highest limits and first access to new models |
........
Carbon's advantage over Argon is documented only by Google so far. In its November 10 announcement Google said Carbon ranks first on CursorBench 4.0, Perplexity's WANDR and Zapier's AutomationBench at more than 2x lower cost per task than the next best external model, and ranks second on the Multimodal Knowledge Agent benchmark at more than 6x lower average cost per task than the leader. Google also reported a per-attempt breach rate of 0.8% in simulated attacks, down from 3.1% on Argon, a 2.17% automated cyberattack query success rate in Gray Swan testing versus 9.86% for Argon, and 92% of tasks passed on a 375-task agentic honesty benchmark against 70% for Argon. These are vendor figures without published independent replication in the sources reviewed for this comparison, and none of them measures the Gemini app experience directly.
Carbon is also the heaviest model to run against the allowance. Google's help page states that more advanced models and higher thinking levels require more usage, so an Ultra subscriber who sets Carbon at High thinking for every request will consume the 5x or 20x allowance faster than the multiplier alone suggests. Google publishes no figure for how much more Carbon consumes than Argon.
··········
APP FEATURES AND AGENTS: WHAT GOOGLE AI PRO AND ULTRA SHARE AND WHERE ULTRA GOES FURTHER.
The feature checklist on Google's limits page marks Pro and Ultra identically. Both include Canvas, Skills, Storybook, connected apps, quizzes and flashcards, Audio Overviews, screen automation, slide generation, Deep Research, the Daily Brief, Tasks in Gemini, Nano Banana 2 image generation, Nano Banana Pro image redos, video generation, music generation and scheduled actions. The difference on these features lies in how many times they can be used before the allowance runs out.
Ultra adds priority and first-access claims on several of them. The Gemini subscriptions page promises Ultra subscribers first access to Tasks in Gemini in select countries, the highest access to auto browse in Gemini in Chrome, the highest limits in Gemini Notebook and in Gemini for Gmail, Docs and Vids, and priority access to new features including Agent Mode. Gemini Spark, Google's background agent that works across Gmail, Calendar, Drive, Docs, Sheets and Slides, is listed on its own page as available to Google AI Pro and Ultra subscribers aged 18 or older in select countries, so at present it is no longer an Ultra exclusive as it was at I/O.
........
Feature | Google AI Pro | Google AI Ultra 5x | Google AI Ultra 20x | Availability notes |
Deep Research, Canvas, Audio Overviews | Included | Included | Included | Uses more allowance |
Tasks in Gemini | Included (Hydrogen, Argon) | First access, adds Carbon | First access, adds Carbon | Not in the EU, UK, Iceland, Liechtenstein, Norway, Switzerland, Nigeria |
Gemini Spark background agent | Included | Included | Included | Select countries, 18+ |
Auto browse in Gemini in Chrome | Included | Highest access | Highest access | US and India |
Gemini Notebook | 5x more Audio Overviews and notebooks than free | Highest limits | Highest limits | Countries where Notebook is live |
Gemini in Gmail, Docs and Vids | Included | Highest limits | Highest limits | 18+ |
Project Genie world model | No | Listed as Ultra on gemini.google | Yes | Google One footnote limits it to Ultra 20x |
........
Project Genie is the one feature where Google's pages disagree. The Gemini subscriptions page and the Ultra help page describe it as a Google AI Ultra benefit, while a footnote on the Google One plans page says it is "only available with a Google AI Ultra 20x plan", matching the I/O announcement that tied it to the $200 plan. A subscriber who buys the $99.99 plan specifically for Project Genie should check the in-app eligibility before relying on it.
··········
GOOGLE FLOW CREDITS AND VIDEO GENERATION ON PRO AND ULTRA.
Video is where the Ultra plans change the economics most. Google Flow gives every user 50 free credits a day and adds a monthly allowance by plan: 200 credits on Plus, 1,000 on Pro, 10,000 on the $100 Ultra plan and 25,000 on the $200 Ultra plan. Neither daily nor monthly plan credits roll over. Ultra subscribers also pay lower per-clip prices on two Veo models, and only Ultra can upscale to 4K.
........
Flow item | Google AI Pro | Google AI Ultra $100 (5x) | Google AI Ultra $200 (20x) |
Monthly plan credits | 1,000 | 10,000 | 25,000 |
Daily credits for all users | 50 | 50 | 50 |
Veo 3.1 Lite, 720p, 4 to 8 seconds | 10 credits | 5 credits | 5 credits, or 0 in Lower Priority mode |
Veo 3.1 Fast, 4 to 8 seconds | 20 credits | 10 credits | 10 credits |
Veo 3.1 Quality, 8 seconds | 100 credits | 100 credits | 100 credits |
Omni Flash 1.2, 720p, up to 10 seconds | 3 credits per second | 3 credits per second | 3 credits per second |
4K upscaling, 1 to 10 seconds | Not available | 50 credits | 50 credits |
Flow Music monthly credits | 10,000 | 30,000 | 30,000 |
........
Converting the monthly plan credits into clips shows how wide the gap is, before the 50 daily credits that every account receives. The calculation below divides each plan's monthly credits by Google's listed per-clip prices and rounds down.
........
Clips from monthly plan credits | Google AI Pro (1,000) | Ultra $100 (10,000) | Ultra $200 (25,000) |
Veo 3.1 Lite clips | 100 | 2,000 | 5,000 |
Veo 3.1 Fast clips | 50 | 1,000 | 2,500 |
Veo 3.1 Quality 8-second clips | 10 | 100 | 250 |
Omni Flash 1.2 clips, 720p, 10 seconds (30 credits) | 33 | 333 | 833 |
Plan price per 1,000 monthly credits | $19.99 | $10.00 | $8.00 |
........
On Veo 3.1 Lite, the $100 Ultra plan yields 20 times as many clips as Pro for 5 times the price, because it combines ten times the credits with half the per-clip cost. A Pro subscriber who uses the 50 daily credits every day of a 30-day month adds 1,500 credits, which more than doubles Pro's monthly total to 2,500 and brings Veo 3.1 Lite output to 250 clips. Veo 3.1 Fast and Veo 3.1 Quality are scheduled to retire from Flow on December 5, 2026, so the Lite and Omni Flash 1.2 rows are the ones that will still apply in 2027.
··········
GOOGLE ANTIGRAVITY, COLAB AND CLOUD CREDITS: THE DEVELOPER SIDE OF EACH PLAN.
Both plans include Google Antigravity, Google's agentic coding app for Windows, macOS and Linux, with different quotas. The Antigravity plans documentation describes Pro as "a high, generous quota, refreshed every five hours until the weekly limit is reached" and Ultra as "the highest, most generous quota, refreshed every five hours" with the highest weekly limits and access to third-party models. The Gemini subscriptions page frames the same difference as entry-level rate limits for the agent model on Pro and 5x or 20x higher rate limits on Ultra. Users who reach the baseline quota can let Antigravity draw on purchased AI credits automatically, or block overage with the "Never" setting.
........
Developer benefit | Google AI Pro | Google AI Ultra 5x | Google AI Ultra 20x |
Antigravity quota | Entry-level, 5-hour refresh to a weekly cap | 5x Pro | 20x Pro |
Antigravity models | Gemini models | Gemini 4 Carbon, Gemini models, third-party models | Gemini 4 Carbon, Gemini models, third-party models |
Google Colab compute units per month | 200 | 1,000 | 2,000 |
Google Cloud credits per month (Developer Program) | $10 | $40 | $100 |
Developer Program premium shareable with family | No | No | No |
........
The Google Cloud credits arrive through the Google Developer Program premium benefit, which requires an active plan linked to the developer profile and cannot be shared with family members. Colab compute units are web-only, limited to users aged 18 or older and to a listed set of countries, and on Pro they are unavailable during a free trial. For a developer who would spend $40 or $100 a month on Google Cloud anyway, the credits offset part of the Ultra price, though they cannot be applied to the subscription itself.
··········
STORAGE, YOUTUBE PREMIUM, GOOGLE HOME AND FAMILY SHARING ON GOOGLE AI PRO AND ULTRA.
Every Google AI plan is also a Google One storage plan. The Google One page lists 5 TB across Gmail, Drive and Photos for Pro, 20 TB for Ultra 5x and 30 TB for Ultra 20x, and the Pro help page notes that some AI Pro plans carry 10 TB. On price per terabyte, Pro is the cheapest of the three at $4.00 a month per TB on monthly billing, against $5.00 for Ultra 5x and $6.67 for Ultra 20x.
........
Bundled benefit | Google AI Pro | Google AI Ultra 5x | Google AI Ultra 20x |
Storage across Gmail, Drive, Photos | 5 TB (10 TB on some Pro plans) | 20 TB | 30 TB |
YouTube | YouTube Premium Lite, select countries, plan manager only | YouTube Premium individual, 40+ countries | YouTube Premium individual, 40+ countries |
Google Home Premium | Standard ($10/month value), 30 days of event history | Advanced ($20/month value), 24/7 history | Advanced ($20/month value), 24/7 history |
Google Health Premium | Included, needs a Pixel Watch or Google Health device | Included, same device requirement | Included, same device requirement |
Family sharing | Up to five others, select AI benefits | Up to five others, select AI benefits | Up to five others, select AI benefits |
AI credit purchases in a family plan | Plan manager only | Plan manager only | Plan manager only |
........
The YouTube benefit differs in scope as well as in name. Premium Lite on Pro removes most ads and adds offline and background playback on YouTube and YouTube Kids, but it excludes YouTube Music Premium, cannot be shared, does not activate for anyone who already pays for YouTube Premium, and stays unavailable until a free Pro trial converts to a paid subscription. Ultra includes the full YouTube Premium individual plan with YouTube Music. Family members on both plans share select AI benefits at no extra cost, with per-person daily limits on features such as Photo to video and Remix.
··········
ELIGIBILITY, COUNTRIES AND BILLING RULES FOR BOTH GOOGLE AI PLANS.
Google AI Plus, Pro and Ultra are sold in more than 150 countries and territories, according to the Google One and Gemini subscription pages, and the Gemini app features of all paid AI plans are limited to users aged 18 or older. Several benefits have narrower footprints than the plans themselves: Carbon in AI Mode is limited to select countries, auto browse in Chrome to the United States and India, Tasks in Gemini excludes the EU and the UK, and the YouTube Premium individual plan bundled with Ultra is offered in over 40 countries.
The billing structure favors Pro for anyone who commits for a year. Pro offers monthly and annual subscriptions, and annual billing lowers the effective price to $16.67 a month. The Google One plans page shows Ultra with monthly billing only, which means an Ultra subscriber can drop back to Pro in a quieter month without losing a prepaid year. The Pro help page lists free trials of Google AI Pro and AI Pro Student without giving the trial length, and it notes that Colab and YouTube Premium Lite are excluded during a trial.
··········
GOOGLE AI PRO VS ULTRA: WHAT GOOGLE DOES NOT PUBLISH.
Several figures a buyer would want are missing from Google's official pages. Google publishes no absolute message counts for the 5-hour window or the weekly cap on any plan, only multipliers, and it states that limits may change without notice. There is no published figure for how much faster Carbon consumes the allowance than Argon, no price list for AI credit packs on the help pages, and no trial length for Pro in the help center.
The plan pages also leave some inconsistencies unresolved. The Google One plans table and Google's help pages list "Gemini 3.1 Pro" or "Gemini 3 Pro" among the benefits of both plans while the in-app model page lists a "Gemini Pro" option only for Pro subscribers. Project Genie is described as an Ultra benefit on one page and as an Ultra 20x benefit on another. The Gemini Spark page says Pro and Ultra subscribers are eligible in select countries without naming them. Buyers who depend on one of these features should confirm it in the Gemini app's upgrade screen, which reflects the account's actual country and plan.

GOOGLE AI PRO OR GOOGLE AI ULTRA: WHICH PLAN FITS WHICH USER.
The decision table below applies the verified prices, limits and benefits to common usage patterns. For the full lineup including the free tier and Google AI Plus, see our guide to Gemini pricing and subscriptions, and for the lower step of the ladder, our Google AI Plus vs Google AI Pro comparison. Readers weighing Ultra against rival $200 plans can compare it in our ChatGPT Pro vs Claude Ultra vs Google AI Ultra report, and the Carbon rollout is covered in our report on Gemini 4 Carbon for API developers and AI Ultra.
........
User or workload | Recommended plan | Reason |
Daily Gemini user who rarely hits limits | Google AI Pro, annual | Argon and a 1M-token window at $16.67 a month effective |
Writer or analyst who runs out of Pro allowance most weeks | Google AI Ultra 5x | 5x the allowance at the same per-unit price as monthly Pro |
User who needs Carbon for hard reasoning or long agent tasks | Google AI Ultra 5x | Cheapest consumer plan with Carbon in the app, Tasks and Antigravity |
Developer coding all day in Antigravity | Google AI Ultra 20x | 20x the Pro quota, third-party models, $100 Cloud credits |
Video creator using Flow every day | Google AI Ultra 20x | 25,000 credits, half-price Veo 3.1 Lite, free Lower Priority Lite clips |
Occasional video maker | Google AI Pro | 1,000 credits plus 50 daily credits cover about 250 Veo 3.1 Lite clips |
Household that mainly wants storage and YouTube | Google AI Pro or Ultra 5x | Pro is cheapest per TB; Ultra adds full YouTube Premium and 20 TB |
User interested in Project Genie | Google AI Ultra 20x | The only plan every Google page lists as eligible |
........
Pro remains the right default because it already carries Argon, the full 1M-token context window and every feature on Google's checklist, and annual billing makes it the cheapest per unit of usage below the top tier. The $99.99 Ultra plan earns its price for subscribers who need Carbon or who regularly hit the Pro cap, since its usage costs the same as monthly Pro and it adds ten times the Flow credits. The $199.99 Ultra plan is the efficient choice for people who would otherwise exhaust the $99.99 plan, because it doubles the price for four times the allowance and is the only tier with free lower-priority Veo 3.1 Lite generation and undisputed access to Project Genie.
