Google AI subscriptions and quota
Your subscription tier decides which models you can use, how much, and whether you get Google Cloud credit. This page covers payment, quota, and how Pro entitlements map onto the family. For how each product works, see its own page. The full four-tier table lives only in the cheatsheet.
One thing to get straight first
The family is not unlocked by a single subscription. There are two separate paid entry points:
| Entry point | Covers | Aimed at |
|---|---|---|
| Google AI subscription (Plus / Pro / Ultra) | usage for the Gemini app, Jules, Antigravity, Flow and so on | individual developers |
| Gemini Code Assist Standard / Enterprise | IDE extension capability and compliance features | teams and organisations |
Buying personal AI Pro does not turn Code Assist into the enterprise product — they are separate. Team compliance requirements are met by the Code Assist edition, not by a personal subscription.
Since 2026-06-18, individual / Pro / Ultra accounts can no longer reach Gemini CLI or the Code Assist IDE extensions via Login with Google. The individual terminal and IDE entry point is Antigravity. Standard / Enterprise and paid API keys are unchanged. Official deprecation.
The four tiers
Subscriptions come in four tiers: AI Plus / AI Pro / AI Ultra 5x / AI Ultra 20x. Storage, model multipliers, Cloud credit and monthly Flow credits are compared in the cheatsheet and are not duplicated here.
A few facts that actually change which tier you should pick:
1. Extended context starts at Pro. The official comparison marks Pro and above as 1,000,000 tokens. This is the only context figure in the family that can be cited.
2. Google Cloud credit exists only at Pro and above. It is delivered through the Google Developer Program: Pro US$10/month, Ultra 5x US$40/month, Ultra 20x US$100/month. If you intend to use the Gemini API or Vertex AI, this is the main reason to choose Pro over Plus.
3. Quota for the agent products is described only qualitatively. The official comparison for Jules and Antigravity says only that "task count and concurrent task count increase with the tier" and gives no specific numbers.
4. Flow credits are numeric. 50/day on the free trial, 200/month on Plus, 1,000/month on Pro, 10,000 or 25,000/month on Ultra. Details live only on Flow.
Coding-relevant Pro entitlements
Source: Use Google AI Pro benefits. Only the items a frontend engineer will actually hit; the rest of the subscription list is not copied here.
| Entitlement | For a frontend engineer | Where to read it |
|---|---|---|
| Google Flow | landing-page / launch / product-demo video | Flow (credits live on that page) |
| Google Antigravity higher limits and prioritized traffic | the individual daily entry point after 2026-06-18 | Antigravity |
| Jules higher task / concurrency / model access | asynchronous cloud PRs | Jules |
| Google AI Studio | tune the model, call the API; Pro raises the Gemini 3.1 Pro and Nano Banana Pro caps | AI Studio |
| Gemini in Android Studio | higher completion and reasoning quota on Android projects; code is not used for training | no standalone page; IDE entry is Code Assist |
| Google Developer Program premium | US$10 Cloud credit, higher Code Assist quota, 30 Firebase Studio workspaces. Cannot be shared with family-group members | Developer Program |
| Gemini app + Deep Research | in-depth research outside the editor | Deep Research |
| Gemini Spark (US only) | a personal agent inside Gemini apps that runs workflows against a goal | no standalone page; official note |
| Gemini Notebook | research / writing assistant; Pro raises Audio Overviews and similar caps, up to 300 sources per notebook | no standalone page; official note |
| Gemini in Chrome auto browse (US only) | Gemini in Chrome runs multi-step web tasks (compare prices, book a hotel). Chrome 144+ | no standalone page; official note |
| Google Flow Music | songs / music videos; Pro maps to Flow Music's Plus plan: 10,000 music credits / month (~2,000 songs), 12 concurrent generations. Separate from Flow video credits | flowmusic.app |
When the allocation runs out, Pro / Ultra can buy extra AI credits for Gemini, Flow and Antigravity. How to manage them: Manage AI credits.
What else the plan includes
The same Pro plan also includes Dreambeans (US only), Health Premium, Home Premium, TV Create Hub (US only), Gemini in Earth, and Photos Remix / Photo to video. None of that is about coding. This site does not document them.
Which tier to pay for
Decide by which tool you mainly use, not by which tier has the longest feature list:
| Your main usage | Suggestion | Reasoning |
|---|---|---|
| Occasional questions in the terminal | start on the free quota | upgrade when you run out, do not pre-buy |
| Daily terminal work on a personal account | Pro + Antigravity | after 2026-06-18, individual / Pro / Ultra no longer use Gemini CLI via Login with Google |
| Gemini CLI daily (Standard / Enterprise or API key) | Pro | extended context and Cloud credit both start here |
| Integrating through the Gemini API | Pro or above | mostly for the US$10 Cloud credit |
| Heavy Jules / Antigravity task volume | Ultra | concurrency and task count rise with the tier |
| Regular landing-page / product-demo video | Pro or above + Flow | monthly credits jump from 200 to 1,000; the free 50/day is only a trial |
| A hard team compliance requirement | use a Code Assist edition | personal subscriptions do not offer VPC-SC or IP indemnification |
The order matters: exhaust the free quota until it genuinely is not enough, then upgrade. Doing it the other way round means paying for capacity you never use, and never learning your real order of consumption.
Credit is not a hard cap
This is the easiest trap: Google Cloud credit is money you were given. Nothing stops automatically when it runs out, and the overage bills normally.
Set a budget before running any batch script:
GCP console → Billing → Budgets & alerts → create a budget
↓
set the amount to your credit amount (US$10 on Pro)
↓
alert thresholds: 50% / 90% / 100%Note that a budget only sends notifications; it does not disable the service. For a genuine hard stop, the official documentation's approach is to publish budget notifications to Pub/Sub and have a function unlink the billing account, which you have to build yourself:
The two operations most likely to overspend: a single long-context call (far more expensive than an interactive exchange) and unattended batch scripts. Configure the budget before either.
Security practices
Beyond quota, these are worth setting up:
| Practice | How |
|---|---|
| Let the agent auto-execute only in trusted directories | Gemini CLI security.folderTrust.enabled, see the cheatsheet |
| Isolate agent changes on their own branch | branch before starting, review by diff afterwards |
| Human confirmation for important changes | Jules plan approval, Antigravity plan artifacts |
| Read the changes regularly instead of only the conclusion | an agent's verification record is a hint, not a substitute for review |
⚠️ Older docs contained configuration keys such as
security.allowedCommands/security.deniedCommands/security.sandboxMode. They do not exist in the official documentation. The security-related settings that really exist are a small set including folder trust, listed in the cheatsheet.
