How to Compare Two AI Model Versions Before Switching Production Traffic

A new model may score better overall while performing worse for a specific task, cohort, or safety boundary.

Checks to make

Use the same representative evaluation set, compare task-level quality and latency, review error severity and subgroup results, and run shadow or limited traffic where appropriate. Define acceptance criteria and rollback triggers before promotion.
