How does a Mac Mini become a no-cloud AI server for a team?

Ollama plus Open WebUI on the Mini, accessible only on the office network: every employee gets a chat assistant in the browser, and the data path begins and ends inside your walls. No per-seat licensing, no vendor DPA to negotiate, no usage logs held by a third party.

Lock it down like any internal server: LAN-only binding or a firewall rule, user accounts in the web UI, the Mini itself under disk encryption. A 16GB base unit serves a small team at 9B quality; step to an M4 Pro for the 14B tier.

Frequently Asked Questions

What is the best privacy model for Mac Mini?

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

Is a Mac Mini AI server compliant for no-cloud policies?

It fits the core requirement: prompts, documents, and outputs never leave hardware you own. Inference happens on the Mini, access stays on your LAN, and there is no third-party processor to audit. Review remains internal.

How many users can one Mini support privately?

A small office for chat-style use: requests queue briefly at busy moments since the base M4 serves one generation at a time. For heavier concurrent demand, a Mac Studio runs the same private stack with several times the throughput.
