Google has officially launched the open-source AI agent tool **Gemini CLI**, seamlessly integrating the powerful capabilities of Gemini AI into developers' terminals. This tool, based on the **Gemini2.5Pro** model, has quickly become a focal point in the developer community due to its lightweight, efficient, and free characteristics. Gemini CLI supports a context window of up to 1 million tokens, offers 60 free requests per minute and 1000 per day, is released under the Apache 2.0 open-source license, and requires only a Google account to use for free, providing an unmatched cost-effectiveness for developers.
Gemini CLI is powerful, integrating Google's real-time online search capabilities to ensure dynamic information updates and assist with research and problem-solving. It supports plugin extensions and custom prompts, enabling seamless integration into various workflows to meet personalized needs. The non-interactive mode facilitates script automation, while collaboration with **Gemini Code Assist** in VS Code provides multi-step reasoning, automatic recovery, and intelligent suggestions, significantly improving code writing and debugging efficiency. In addition, Gemini CLI integrates the MCP protocol, the video generation tool Veo, and the image generation tool Imagen, supporting multimodal content creation, suitable for programming, automation, and creative projects.
Compared to Anthropic's Claude Code, Gemini CLI lags slightly in code repository understanding and engineering performance, but its free high quota and open-source nature make it highly attractive to developers with limited budgets. The community response has been enthusiastic, and the official Google blog described its features and quotas as "unparalleled," especially favored by command-line enthusiasts.
Developers can access the open-source repository via GitHub and get started quickly by logging into their Google account. The official blog provides detailed guides and example code to help users use it efficiently. **Gemini CLI**, with its lightweight, free, and powerful features, not only meets programming and automation needs but also opens up endless possibilities for research and creative projects, becoming a new tool in the developer's toolkit.
