Access large language models from the command-line

LLM

A CLI utility and Python library for interacting with Large Language Models, both via remote APIs and models that can be installed and run on your own machine.

Run prompts from the command-line, store the results in SQLite, generate embeddings and more.

Full documentation: llm.datasette.io

Background on this project:

• llm, ttok and strip-tags—CLI tools for working with ChatGPT and other LLMs
• The LLM CLI tool now supports self-hosted language models via plugins
• Accessing Llama 2 from the command-line with the llm-replicate plugin
• Run Llama 2 on your own Mac using LLM and Homebrew
• Catching up on the weird world of LLMs
• LLM now provides tools for working with embeddings
• Build an image search engine with llm-clip, chat with models with llm chat
• Many options for running Mistral models in your terminal using LLM

Installation

Install this tool using pip:

pip install llm

Or using pipx:

pipx install llm

Detailed installation instructions.

Getting started

If you have an OpenAI API key you can get started using the OpenAI models right away.

As an alternative to OpenAI, you can install plugins to access models by other providers, including models that can be installed and run on your own device.

Save your OpenAI API key like this:

llm keys set openai

This will prompt you for your key like so:

Enter key: <paste here>

Now that you've saved a key you can run a prompt like this:

llm "Five cute names for a pet penguin"

1. Waddles
2. Pebbles
3. Bubbles
4. Flappy
5. Chilly

Read the usage instructions for more.

Installing a model that runs on your own machine

LLM plugins can add support for alternative models, including models that run on your own machine.

To download and run Llama 2 13B locally, you can install the llm-mlc plugin:

llm install llm-mlc
llm mlc pip install --pre --force-reinstall \
  mlc-ai-nightly \
  mlc-chat-nightly \
  -f https://mlc.ai/wheels
llm mlc setup

Then download the 15GB Llama 2 13B model like this:

llm mlc download-model Llama-2-13b-chat --alias llama2

And run a prompt through it:

llm -m llama2 'difference between a llama and an alpaca'

You can also start a chat session with the model using the llm chat command:

llm chat -m llama2

Chatting with mlc-chat-Llama-2-13b-chat-hf-q4f16_1
Type 'exit' or 'quit' to exit
Type '!multi' to enter multiple lines, then '!end' to finish
