Structured Logs for Predictions
Log inputs, outputs, and latency as JSON.
Why Log Predictions
Once your model serves real users, you cannot watch it by hand. Logging every prediction is how you see what it actually does in production. 📊
Plain Text Is Painful
A log line like "got request, returned 0.91" reads fine to you but is brutal to search at scale. Machines need structure, not prose.
