Google has launched Gemini CLI, a free and open-source command-line AI assistant designed to help developers code, debug, automate tasks, and streamline workflows — all through natural language commands. The tool is powered by Gemini 2.5 Pro, one of Google’s most advanced AI models, and is now available globally.
Unlike browser-based AI tools, Gemini CLI works directly in the terminal — the environment where developers already spend most of their time. This release signals Google’s growing focus on developer-centric AI infrastructure, combining speed, flexibility, and intelligent support in one lightweight utility.
Gemini CLI: AI That Lives in the Terminal
Gemini CLI is a Python-based utility that brings Gemini AI into the command-line interface (CLI), allowing developers to interact with the model using conversational prompts. Whether writing code, fixing bugs, or running commands, users can now do so by simply telling the AI what they want — no need for memorizing complex syntax or terminal commands.
Speaking at the launch, Taylor Mullen, Senior Staff Software Engineer at Google, said, “You can tell your computer what you want to achieve rather than struggling with how to say it in the computer’s native tone.” He added that the tool is designed to be more than just a coding assistant — it’s also helpful for task automation, deep research, and project-level support.
Integrated with Gemini Code Assist
Gemini CLI is deeply integrated with Gemini Code Assist, Google’s AI-based development assistant for IDEs like Visual Studio Code. This allows developers to use the same underlying Gemini 2.5 Pro model in both their terminal and their editor, ensuring consistency across environments.
With agent mode enabled, Gemini Code Assist can plan multi-step solutions, fix bugs, write test cases, and generate code tailored to the developer’s project structure. The combination of Gemini CLI and Code Assist offers developers flexibility: they can switch between their terminal and editor without sacrificing context or capability.
Free Access with Industry-Leading Limits
To make Gemini CLI accessible, Google is offering free access to Gemini 2.5 Pro through its Gemini Code Assist plan. Anyone with a personal Google account can activate the tool, which includes usage limits of 60 model requests per minute and 1,000 requests per day — among the most generous free tiers currently available for any AI coding assistant.
Developers with larger-scale needs can use Google AI Studio or Vertex AI for usage-based billing or subscribe to Gemini Code Assist’s standard or enterprise plans.
Built for Flexibility, Privacy, and Extensibility
Gemini CLI is fully open source under the Apache 2.0 license, and the codebase is available on GitHub. Developers can inspect how the tool works, submit pull requests, suggest features, or fork it to customize the assistant for their own workflows.
The tool also supports the Model Context Protocol (MCP), which allows external data and web content to be integrated into the model’s responses. Developers can customize the assistant’s behavior using system prompts, bundled extensions, and team-specific configurations. For automation use cases, Gemini CLI can be invoked non-interactively within scripts, making it suitable for DevOps pipelines and CI/CD workflows.
Designed for the Way Developers Work
With Gemini CLI, Google is focusing on the reality of how modern developers operate. The terminal remains a critical interface for engineers, system administrators, and backend developers — and Gemini CLI enhances that environment without disrupting it.
The tool’s natural language interface lowers the learning curve for new developers and speeds up experienced ones by reducing context switching and manual debugging. It’s particularly useful for developers working in headless environments, Linux shells, or cloud-based containers where GUI tools are unavailable.
Tailored Code, Not Just Boilerplate
One of the most promising aspects of Gemini CLI is its ability to analyze the user’s local codebase and generate tailored solutions. According to Google, the assistant understands project-level context, including dependencies, function definitions, and naming conventions — enabling it to generate code that fits seamlessly into existing workflows.
Unlike simple command-completion tools, Gemini CLI’s responses are shaped by the structure and patterns within your specific project — making the assistance feel less generic and more intelligent.
Final Thoughts
With Gemini CLI, Google has delivered an AI assistant that fits naturally into developers’ workflows. It’s fast, open, free to try, and deeply integrated with the tools developers already use. By bringing Gemini 2.5 Pro into the terminal, Google has created a hands-on AI experience that doesn’t just talk about productivity — it actually delivers it.
For coders working across operating systems, scripting environments, or cloud terminals, Gemini CLI may quickly become an essential part of their daily toolkit.
