GDX Spark is extremely slow on a short LLM test

Tutorial: Build llama.cpp from source and run Qwen3 235B

This is hopefully a simple tutorial on compiling llama.cpp on the DGX Spark, once compiled, it can be used to run GGML-based LLM models directly on the command line, served as an OpenAI compatible API, or accessed via a web browser (which is what we’ll be doing for this tutorial). As of 25 November 2025, all build tools and dependencies needed to compile llama.cpp is already installed on the DGX Spark, so you can literally just clone the repository and build it. Since Qwen3 235B is slightly to…

It is a tutorial to build from source, but it should hopefully not be too bad. Check the extra note I added further down to add curl support as well, which will allow it to grab models straight from huggingface.
