In the same boat. I love running things localhost. It's been great fun, and I learned tons I didn't know before. I know remote models API-s are a must for any serious work where tons is to be done, produced fr. Still it warms my heart every time llama-server runs on, and serves my aging mbp. Recent MoEs run great on macs with loads of v/ram, and the power efficiency is scarcely believable.
