Gemini CLI

[!IMPORTANT] Read before installing — Gemini CLI status & tool guide

• Enterprise Code Assist only: Designed for Gemini Code Assist Standard / Enterprise licenses and Code Assist for GitHub on Google Cloud (your access remains unchanged).
• No free tier or Google AI plans: Free individual access and Google AI Pro / Ultra (Google One) moved to Antigravity CLI on June 18, 2026 (transition post).
• Not optimized for Gemini 4+: Not tuned for the Gemini 4 series (for example, Gemini 4 Argon) or future releases in this or later generations.
• Not for model benchmarks: Don't use Gemini CLI to benchmark Gemini models—its harness isn't tuned for Gemini 4+ and produces unrepresentative scores.

Which Google CLI do you need?

Tool	Best for	Links
Antigravity CLI (agy)	Interactive multi-agent coding terminal. Use for Gemini 4 Argon+, free / Google AI Pro & Ultra accounts, or Google Cloud.	Download · Migrate · Argon post
Gemini API CLI (gemini-api)	Stateless API CLI (not a coding harness). Gives agents (agy, Claude Code, Codex), scripts, and CI direct commands for Gemini models, media gen, file analysis, and managed agents.	GitHub · Releases · API docs
Gemini CLI (gemini, this repo)	Organizations with Gemini Code Assist Standard / Enterprise or Code Assist for GitHub on Google Cloud (plus legacy paid API / Vertex keys).	Docs

Gemini CLI (gemini) is an open-source terminal agent maintained for enterprise Gemini Code Assist workflows on Google Cloud. Learn more in the Gemini CLI documentation.

🔐 Authentication Options

Choose the authentication method that best fits your needs:

Option 1: Sign in with Google (OAuth login using your Google Account)

When using a paid Code Assist License from your organization, remember to set the Google Cloud Project

# Set your Google Cloud Project
export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"
gemini

Option 2: Gemini API Key

✨ Best for: Developers who need specific model control or paid tier access

Benefits:

• Model selection: Choose specific Gemini models
• Usage-based billing: Upgrade for higher limits when needed

# Get your key from https://aistudio.google.com/apikey
export GEMINI_API_KEY="YOUR_API_KEY"
gemini

Option 3: Vertex AI

✨ Best for: Enterprise teams and production workloads

Benefits:

• Enterprise features: Advanced security and compliance
• Scalable: Higher rate limits with billing account
• Integration: Works with existing Google Cloud infrastructure

# Get your key from Google Cloud Console
export GOOGLE_API_KEY="YOUR_API_KEY"
export GOOGLE_GENAI_USE_VERTEXAI=true
gemini

For Google Workspace accounts and other authentication methods, see the authentication guide.

🚀 Getting Started

Basic Usage

Start in current directory

gemini

Include multiple directories

gemini --include-directories ../lib,../docs

Use specific model

gemini -m gemini-2.5-flash

Non-interactive mode for scripts

Get a simple text response:

gemini -p "Explain the architecture of this codebase"

For more advanced scripting, including how to parse JSON and handle errors, use the --output-format json flag to get structured output:

gemini -p "Explain the architecture of this codebase" --output-format json

For real-time event streaming (useful for monitoring long-running operations), use --output-format stream-json to get newline-delimited JSON events:

gemini -p "Run tests and deploy" --output-format stream-json
