LLM is a CLI utility and Python library designed for interacting with Large Language Models. It allows users to work with remote APIs, as well as models that can be installed and run locally. Users can run prompts from the command-line, store results in SQLite, generate embeddings, and explore a variety of plugins for accessing remote and local models. The project offers comprehensive documentation, including detailed installation instructions and usage guidelines. LLM supports OpenAI models and provides the option to install plugins for models from other providers. Users can save their OpenAI API key and run prompts to generate responses. The tool can also be installed using `pip` or Homebrew. Various blog posts provide background on the project and its features, making it a valuable resource for working with diverse language models in different environments.
