Local LLMs 202: The Local LLM Toolchain: uv, uvx, Ollama, and Model Files

A local LLM setup can feel messy because several tools appear at once: Python environments, command-line utilities, model downloaders, model runtimes, chat interfaces, and APIs. The trick is to separate the toolchain into jobs.

For a beginner, four ideas are enough to get oriented: uv, uvx, Ollama, and model files.

Mental model: tools install things, runtimes run models

uv helps manage Python projects, Python versions, dependencies, and Python command-line tools. Ollama runs language models and exposes them through a local API. A model file contains the model weights and metadata that the runtime needs.
