How do you share one Mac Mini chatbot with the whole house?

Install Ollama plus a web UI (Open WebUI is the common pick), expose it on your LAN, and every phone, tablet, and laptop at home gets a private chat assistant in the browser, no accounts, no cloud, no per-seat fees. The Mini idles at a few watts, so leaving it on costs almost nothing.

The base 16GB config is the value play: a 9B model covers homework help, drafting, and general Q&A for a family. Multiple simultaneous users queue briefly rather than crash. Ollama processes requests one at a time at this scale.

Frequently Asked Questions

What is the best chat model for Mac Mini?

With 16GB RAM, Qwen3.5 9B Instruct is the best chat model for Mac Mini. It fits within the 11GB memory budget and delivers the highest quality for chat tasks. Run it with: ollama run qwen3.5:9b

Can several people chat with one Mac Mini at the same time?

Yes, with brief queuing. Ollama serves requests sequentially on a base M4, so two simultaneous questions take turns, barely noticeable for chat-length replies. A web UI like Open WebUI handles the multi-user part.

How much power does an always-on Mac Mini chatbot use?

Very little. The M4 Mini idles around a handful of watts and only spikes during generation. As a 24/7 private assistant it costs a fraction of a single cloud subscription per year in electricity.
