A roughly $600 Mac Mini M4 can run private, local AI 24/7 for about $3 a month in electricity—an estimate now spreading through developer circles as an alternative to cloud AI.

A $599 Mac Mini Can Run Your Own AI — for About $3 a Month
A base M4 Mac Mini can host a private, always-on local LLM around the clock for roughly the cost of a coffee — replacing cloud subscriptions that can top $170–200 per month.
~$599
One-time hardware (16GB / 256GB base M4)
~$3/mo
Electricity for 24/7 operation (at $0.15/kWh)
~8 mo
Payback vs. a cloud subscription
Power draw, 24/7 — Mac Mini vs. Windows-class PC server
Watts at typical idle / standby (which dominates always-on cost)
100W+
Windows PC server
Standby draw dominates the bill — inference (peaks 30–65W) adds little. Apple Silicon's Unified Memory + low idle is the edge for round-the-clock use.
Why it works
One-time $599 + tiny power bill, no token limits
Quiet, low-heat — runs even in a closet
Data never leaves your machine (privacy)
Ollama's Anthropic API support swaps cloud tools to local with little rewriting
Where it's limited
16GB base struggles with 70B+ models — practical range is quantized 7B–35B
Bigger models need more RAM or clustering (EXO)
Sustained heavy loads can thermal-throttle
Setup & model tuning take effort; M4 Pro price was hiked
Scaling up: a small cluster
Some run 4–5 units clustered for content generation and workflow automation — drawing about 200W at full load , around $12 a month in electricity. Actual cost depends on power rates, model size, and usage.
