Google Accidentally Leaks Its Open-Source Gemini CLI Ahead of Launch

Google appears to have prematurely unveiled Gemini CLI, an open-source command-line interface that brings its Gemini AI models directly into developers’ terminals. The tool is slated to be publicly accessible, offering high-capacity usage for free and full integration with Google’s AI-powered coding assistant, Gemini Code Assist.

Gemini CLI, released under the Apache 2.0 license, is designed as a local utility for coding, content creation, research, and task automation. It connects users to Gemini 2.5 Pro with a substantial one-million-token context window and allows up to 1,000 free requests daily. Users simply need a personal Google account to begin.

“Gemini CLI offers the industry’s largest usage allowance at 60 model requests per minute and 1,000 model requests per day at no charge,” the archived announcement mentioned. “It provides the most direct path from your prompt to our model.”

🚨 Breaking: Google will soon launch Gemini CLI, a powerful open-source AI agent built for the terminal.

The interface supports extensibility via the Model Context Protocol (MCP) and allows users to invoke AI non-interactively within scripts. Prompt grounding with Google Search and support for structured system prompts via GEMINI.md are also built in. This emphasises Google’s aim to make Gemini an adaptable, scriptable agent environment.

The release also aligns Gemini CLI with Gemini Code Assist, enabling seamless handover between terminal and IDE workflows. 

The Gemini Code Assist is a free AI coding tool that supports all programming languages and offers features like code completion, generation, chat, and natural language prompts, with up to 1.8 lakh code completions per month.

Gemini CLI’s sudden appearance follows Google’s recent push towards open agentic frameworks and high-trust developer tooling. Its GitHub repository is not currently accessible and is expected to appear at http://github.com/google-gemini/gemini-cli.

As of now, there has been no official correction or clarification from Google regarding the apparent leak.
