Gemini CLI FAQ

Is Gemini CLI free?: Gemini CLI itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
Do I need to install anything or write code to use Gemini CLI?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does Gemini CLI work on a phone?: No. It needs a computer.
Can I use Gemini CLI commercially?: The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
