The Gemini family
Google's AI coding and creative product line. This page is the product map plus a decision tree: first "what am I trying to do → which product", then the individual pages.
Since 2026-06-18: individual accounts and Google AI Pro / Ultra can no longer use Gemini CLI or the Code Assist IDE extensions via Login with Google. Move to the Antigravity family. Standard / Enterprise licences and paid API keys are unchanged. Official sources: consumer-account deprecation and the transition announcement.
Product map
The coding line is split by who is driving. Film and prototypes sit where Claude Design sits in that family — they do not compete with the terminal.
Gemini family
├── Coding line (who is driving)
│ ├── you type, AI completes → Code Assist
│ ├── you instruct, AI runs it in your terminal → Gemini CLI
│ ├── you set a goal, AI plans and executes → Antigravity
│ └── you hand over a task, AI returns a PR → Jules
├── Prototypes and film (Claude Design counterpart)
│ ├── a clickable interactive prototype → Canvas
│ └── landing-page / launch / product-demo video → Google Flow
├── Models and subscription
│ ├── tune the model, call the API → AI Studio
│ └── which tier, how much quota → Google AI plans
└── Also in Pro, no standalone tutorial
├── Gemini Spark (US, personal agent)
├── Gemini Notebook (research / writing)
├── Gemini app + Deep Research
├── Gemini in Chrome auto browse (US)
├── Gemini in Android Studio
└── Google Flow Music (flowmusic.app; credits separate from Flow)Dreambeans, Health Premium, Home Premium, TV Create Hub, Earth and Photos Remix travel with the same subscription and are irrelevant to coding. This site does not document them. One line lives on the subscription page.
Quick decision: which one?
What am I trying to do?
├── Write / debug / refactor / open a PR
│ ├── In the terminal, into a pipe?
│ │ ├── personal account → Antigravity CLI
│ │ └── Standard / Enterprise or an API key → Gemini CLI
│ ├── Cross-module, watch it as it works? → Antigravity
│ ├── Clearly bounded, hand it off for a PR? → Jules
│ └── Stay in the IDE, or the team has a hard compliance need? → Code Assist
├── Interactive prototype / a page you can click
│ └── → Canvas
│ └── once you pick a direction → Antigravity writes it into the repo
├── Landing-page film / product demo / storyboard
│ └── → Google Flow
│ └── songs / music videos → Flow Music (separate credits; no extra tutorial)
├── Temperature, pinned system prompt, large context, API
│ └── → AI Studio

Core products
Tutorials stay expanded. The Cookbook sits next to them and stays expanded too.
| Product | In one line | When to use it |
|---|---|---|
| Gemini CLI | an AI agent in your terminal | you want AI in pipes and scripts; the family's conceptual entry point |
| Antigravity | agent-first development platform | large cross-module changes you want to verify as they happen |
| Jules | asynchronous cloud coding agent | clearly bounded, time-consuming work you hand off and collect as a PR |
| Cookbook | look up a recipe by "what I want to do" | after the main tutorials, when you start doing the work |
More products and extensions
Collapsed by default. Axis A: no prerequisite concepts. Axis B: relevance to frontend engineers — Flow is the Claude Design counterpart, and sits next to Canvas.
| Product | In one line | When to use it |
|---|---|---|
| Canvas | an interactive workspace beside the conversation | a clickable prototype, fast |
| Google Flow | AI creative studio (Veo 3.1 / Nano Banana / Gemini Omni) | landing-page, launch and product-demo video |
| Code Assist | IDE integration | you do not want to change editor; your team has hard compliance requirements |
| AI Studio | model and parameter console | tuning temperature, pinning a system prompt, large-context audits, API integration |
| Google AI subscriptions | tiers and quota | deciding which tier to pay for; drawing Pro entitlements onto the family map |
Reference
Cheatsheet / Glossary stay expanded. Shared tables are written once; other pages only link here.
| Page | Purpose |
|---|---|
| Cheatsheet | decision tables, model status, subscription tiers, configuration paths |
| Glossary | what Rules / Skill / Subagent / Artifact / Flow actually mean |
Suggested learning order
The order follows concept dependency (axis A) plus audience complexity (axis B). It is not alphabetical and not by popularity:
- Start with Gemini CLI. It is the only complete tool in the family with no prerequisites, and it is where
.gemini/settings.json,gemini extensions installandGEMINI.mdare first introduced — all three are reused repeatedly later. Individual / Pro / Ultra accounts should do daily work in Antigravity CLI; this page still starts at the CLI because it is the conceptual entry point, not because consumer Login with Google still works. - Then Antigravity. It reuses those three concepts and adds rules, skills and subagents. After 2026-06-18 this is the daily entry point for individual developers. Skip the CLI and you will get stuck on "what is this configuration file".
- Then Jules. It layers a GitHub repository and PR workflow on top of autonomous agents.
- When you start doing the work, use the Cookbook. Look up parameters in the cheatsheet; when two concepts blur, open the glossary.
- After that, read Canvas / Flow / Code Assist / AI Studio / subscription tiers as you need them. They are independent of each other and do not form a chain. Flow has no axis-A prerequisite; on axis B it is mid-to-high relevance for frontend engineers (you will need it when you present a feature), so it belongs in "more products", not in the core group.
Code Assist comes later not because it is harder, but because its official positioning targets "organizations with strict data security and compliance requirements", which is usually not an individual developer's first need. Subscription tiers come last because they answer "which tier should I pay for", a question that only makes sense once you know which tool you want.
Quick decision
| My situation | Use |
|---|---|
| Want to try AI coding in the terminal | Gemini CLI (enterprise / API key) or Antigravity (individual) |
| Have to change something spanning five modules | Antigravity |
| Have to upgrade React from 18 to 19 | Jules |
| Do not want to leave VS Code | Code Assist |
| Want AI to read the whole repository for an audit | AI Studio |
| Need to show a product manager a prototype within half an hour | Canvas |
| Need a video for a landing page, launch film or product demo | Google Flow |
| Want to know whether the free quota is enough | Subscription tiers |
Shared concepts
A few things are reused across products. Recognising them up front saves a lot of repeated learning:
| Concept | Products |
|---|---|
GEMINI.md | Gemini CLI, Antigravity (global rules) |
AGENTS.md | Jules |
| MCP | Gemini CLI, Antigravity, Code Assist |
| Subscription quota | one subscription affects the available volume of several products |
| Flow credits | Google Flow only; not the same ledger as Flow Music or Antigravity AI credits |
Exact paths and differences are in the glossary and configuration in the cheatsheet.
Subscriptions and quota
Subscriptions come in four tiers, AI Plus / AI Pro / AI Ultra 5x / AI Ultra 20x — not two. Model multipliers, storage and Google Cloud credit per tier are in subscription tiers in the cheatsheet and are not duplicated here. Flow's daily / monthly credits are on Flow. Coding-relevant Pro entitlements are on the subscription page.
