AI turned every developer into a reviewer. The bottleneck moved from writing code to judging it. That judgment is exactly where a cheap model plus a cheap server can earn its keep — if you choose the right job.
Say you maintain a small open-source repo. Every morning, a cron job reads new issues, classifies each one as bug, feature, or question, and drafts a first response. The job is batch, low-volume, and failure-tolerant. Does it belong on a free model and a free server?
This article gives you a glossary, a decision tree, and a worked example at every leaf. No leaderboard arguments. Just a way to decide before you build. It is not a scorecard for model quality; it is a filter for operational fit.
The tools in scope
MonkeyCode is an open-source project that offers free model access and a free server option for automation jobs like this. Disclosure: This article was prepared as part of MonkeyCode's product outreach.
