This article provides a technical guide on how to build a model-swapping harness for LLMs, emphasizing the importance of testing with real user traffic before deploying new models. It outlines a five-stage process, starting with capturing live requests using a Node.js logging proxy and then replaying these requests against a candidate model. The goal is to compare the responses and performance of the new model against the existing production model to ensure a safe and effective transition. AI
