Pre-release testing should be split into two layers: offline evaluation uses a built edge-case library to run batch scoring for rapid iteration; shadow mode uses real traffic for final validation while collecting new problems not covered by the offline case library.

UnverifiedFunnel-style layered evaluation architecture: the first layer uses cheap and fast semantic verifiers to pre-screen large volumes of traces, and the second layer passes ambiguous or high-value samples to a more powerful judge model for detailed evaluation.75% similarUnverifiedThe advantage of Shadow Mode over offline testing is its ability to capture the distribution characteristics of real production traffic, including edge cases that developers did not anticipate.74% similarVerifiedRetrieval and generation must be tested separately; by building a small evaluation set, first check separately whether the retriever recalls the correct evidence, and then evaluate the model's wording.73% similarUnverifiedThe approach of deploying first and evaluating later methodologically corresponds to the Shadow Testing and Online Evaluation paradigms, and is similar in logic to Canary Release73% similarUnverifiedOut-of-sample testing cuts the data in two, using one part for development and the other only once for final validation; walk-forward analysis proceeds on a rolling basis, training on window 1 and testing on window 2, then moving to training on window 2 and testing on window 3, and so on.73% similar
