Gemini CLI: Google's Open Source AI Tool for Terminals

Google Introduces Gemini CLI: An Agentic AI Tool for Developers

Google has announced the release of a novel agentic AI tool designed to integrate its Gemini AI models directly into developers' existing coding environments.

Gemini CLI: Local Execution and Natural Language Interaction

The newly launched Gemini CLI operates locally from a terminal, providing developers with a powerful interface for interacting with AI. This tool establishes a connection between Google’s Gemini AI models and local codebases.

Developers can utilize natural language prompts to request various actions, including code explanation, feature development, debugging assistance, and command execution.

Expanding Google’s AI Coding Toolkit

Gemini CLI represents Google’s ongoing commitment to incorporating AI into developer workflows. The company already provides a suite of AI-powered coding tools, such as Gemini Code Assist and the asynchronous assistant, Jules.

However, Gemini CLI directly challenges established command-line AI tools like OpenAI’s Codex CLI and Anthropic’s Claude Code, which are often favored for their ease of integration, speed, and efficiency.

The Rise of Gemini 2.5 Pro and Developer Demand

Since the introduction of Gemini 2.5 Pro in April, Google’s AI models have gained significant traction among developers. This popularity has fueled the growth of third-party AI coding tools like Cursor and GitHub Copilot.

In response, Google is actively working to foster direct relationships with developers through the provision of its own in-house AI products.

Beyond Coding: Versatile Capabilities of Gemini CLI

While primarily intended for coding tasks, Gemini CLI is designed to handle a broader range of operations. Developers can leverage it to create videos using Google’s Veo 3 model.

Furthermore, the tool facilitates the generation of research reports with the Deep Research agent and provides access to real-time information via Google Search.

Gemini CLI also supports connections to MCP servers, enabling developers to interact with external databases.

Open Source and Generous Usage Limits

To promote widespread adoption, Google is releasing Gemini CLI as an open-source project under the Apache 2.0 license, known for its permissive terms.

The company anticipates contributions from a community of developers on GitHub.

Google is also offering substantial usage limits: free users can make 60 model requests per minute and 1,000 requests per day, exceeding the average usage observed during initial testing.

Considerations Regarding AI Coding Tool Reliability

Despite the increasing popularity of AI coding tools, it’s important to acknowledge potential risks. A 2024 Stack Overflow survey revealed that only 43% of developers fully trust the accuracy of these tools.

Research indicates that code-generating AI models can sometimes introduce errors or overlook critical security vulnerabilities.
