Utility functions for use with Ollama in PowerShell

Want to run AI Large Language Models (LLM) locally? One great way is with Ollama, which can host many state of the art LLMs. Ollama is a command-line utility (CLI) that can be used to download and manage the model files (which are often multiple GB), perform the actual LLM inference, and provide a REST API to expose the LLMs to other applications on your system. Ollama is quick to install.

This repo contains functions for PowerShell. You can dot source this file to make the functions available in your current PowerShell session, or add it to your profile to make them available for every session. This was developed on Windows, but should work as-is on a Linux or [MacOS]
