A command-line interface (CLI) for Google Gemini.

Google Gemini is a family of multimodal artificial intelligence (AI) large language models that have capabilities in language, audio, code and video understanding.

The current version only supports multi-turn conversations (chat), using the gemini-pro model.

To use gemini-cli, you'll need an API key set in the GEMINI_API_KEY environment variable. If you don't already have one, create a key in Google AI Studio.
