Run a 4B LLM model locally on your PC, this has been tested on Windows 10

A developer has published a step-by-step guide for running a 4B-parameter LLM locally on a Windows 10 PC using Mozilla's llamafile tool and a Qwen3 model from Hugging Face. The guide details downloading llamafile v0.10.5 and the qwen3-4b-thinking-2507.Q4_K_M.gguf file, then launching a local server on 127.0.0.1:8080.
