Practical local AI & homelab guides.
Real GPUs, no cloud required.

I’m Mitch. I build, run, and write about AI on the hardware in my home. Here’s what fits, what works, and what needs another try.

What you’ll find here

More from the
hardware you own.

Clear guides for homelab builders who want to get past the first model download.

01 / COMPUTE

Multi-GPU inference

Model fit, quantization, and separate workers across NVIDIA and Intel. Count the memory. Explain the limits.

02 / SOFTWARE

The software stack

Ollama, Open WebUI, vLLM, llama.cpp, and ComfyUI. A useful front door and a clear job for each backend.

03 / HARDWARE

Hardware buying guides

Start with the workload. Look at VRAM, compatibility, power, and what a new card would actually add.

Launch guide · Private preview

Four GPUs, Zero Cloud: Running LLMs Across a Heterogeneous Home GPU Cluster

Three machines, two GPU vendors, and one front door. The first guide covers model placement, honest VRAM math, and a serving setup with private access.

The Ghost publication is in private preview. The guide will be linked here when it’s public.
