For developers, the command line interface (CLI) isn’t just a tool; it’s home. The terminal’s efficiency, ubiquity, and portability make it the go-to utility for getting work done. And as developers’ reliance on the terminal endures, so does the demand for integrated AI assistance.
That’s why we’re introducing Gemini CLI, an open-source AI agent that brings the power of Gemini directly into your terminal. It provides lightweight access to Gemini, giving you the most direct path from your prompt to our model. While it excels at coding, we built Gemini CLI to do so much more. It’s a versatile, local utility you can use for a wide range of tasks—from content generation and problem solving to deep research and task management.
We’ve also integrated Gemini CLI with Google’s AI coding assistant, Gemini Code Assist, so that all developers — on free, Standard, and Enterprise Code Assist plans — get prompt-driven, AI-first coding in both VS Code and Gemini CLI.

Unmatched usage limits for individual developers
To use Gemini CLI free of charge, simply log in with a personal Google account to get a free Gemini Code Assist license. That free license grants access to Gemini 2.5 Pro and its massive 1 million token context window. To ensure you rarely (if ever) hit a limit during this preview phase, Google offers the industry’s largest allowance: 60 model requests per minute and 1,000 requests per day — at no cost.
If you’re a professional developer who needs to run multiple agents simultaneously or prefers specific models, you can use a Google AI Studio or Vertex AI key for usage-based billing, or subscribe to a Standard or Enterprise Code Assist license.

Powerful models in your command line
Now in preview, Gemini CLI brings serious AI power to your terminal, supporting everything from code understanding and file manipulation to command execution and dynamic troubleshooting. It’s a fundamental upgrade to your workflow, enabling you to write code, debug issues, and streamline your tasks using natural language.
Its power comes from built-in tools allowing you to:
• Ground prompts with Google Search, fetching real-time external context.
• Extend functionality via the Model Context Protocol (MCP) or bundled extensions.
• Customize prompts and behavior for your specific use cases.
• Automate workflows by running Gemini CLI non-interactively inside scripts.
Gemini CLI even supports creative use cases — like making a short video about a ginger cat’s adventures across Australia using Veo and Imagen.

Open and extensible
Gemini CLI is fully open source under the Apache 2.0 license, so you can inspect, understand, and verify how it works — including its security implications. Google expects (and encourages) developers to contribute: report bugs, suggest features, improve security, and submit code.
It’s also built to be extensible, based on standards like MCP, system prompt files (GEMINI.md), and flexible settings for both individual and team customization. The terminal is a personal space, and Gemini CLI is designed to adapt to it.
⸻
Shared tech with Gemini Code Assist
Sometimes, an IDE is still the best tool. When that’s the case, Gemini Code Assist delivers. Whether you’re a student, hobbyist, or pro, you get the same tech that powers Gemini CLI — now in VS Code.
Drop a prompt into the chat window using agent mode, and Gemini Code Assist will get to work: writing tests, fixing bugs, building features, or even migrating your code. It builds multi-step plans, recovers from failed paths, and proposes smart alternatives.
Gemini Code Assist’s agent is more than a chatbot — it’s a collaborative, reasoning agent that elevates how you write, review, and refactor code.

Easy to get started
Getting started is dead simple. All you need is an email address to install and run Gemini CLI. With industry-leading free-tier limits, full open source access, and tight IDE integration, Gemini CLI is your new AI-powered sidekick — right inside the terminal.
