Perplexity does not directly reflect downstream task performance, so independent verification and downstream accuracy need to be combined to comprehensively evaluate a compressed model.

UnverifiedGeneration and inference tests exposed failure modes that likelihood alone cannot capture, suggesting that compressed models cannot be evaluated by perplexity alone.75% similarUnverifiedThe gap in generation quality does not represent a gap in representation capability; for downstream prediction tasks, BD's representations can be used directly without bearing the accuracy loss of generative rollout.70% similarUnverifiedTo evaluate whether compression is beneficial or whether switching to a smaller model makes sense, one cannot look only at the drop in Token count per request, but must fix the source input and success criteria while comparing the final task result with the total usage of the entire task (including additional work such as summary generation).70% similarUnverifiedThere is no absolute good or bad in choosing between synchronous and asynchronous; the key is whether strong data dependencies exist between tasks and whether overall rollback is needed after a failure.68% similarUnverifiedA reasonable prediction loss combined with 0% downstream control accuracy is highly consistent with representation collapse, meaning the encoder has fooled the self-supervised objective without learning any useful dynamic information.68% similar
