1A guide to local coding models
- The author initially hypothesized that buying expensive hardware to run local AI coding models would be more cost-effective than paying $100+ monthly subscriptions, but later corrected this conclusion. After testing with a 128GB MacBook Pro, they found local models can handle about 90% of coding tasks well but struggle with the critical final 10%. While local models offer benefits like reliability, privacy, and availability, they're better as supplements to cloud services rather than replacements for professional work. The setup process is complex and tooling remains finicky, making cloud subscriptions more practical for production environments despite higher costs.
