UnverifiedWhen committing to 95% accuracy, a difficulty-based routing strategy costs 32% of what always using the large model costs.79% similarUnverifiedIn tasks with propositional constraints, the proportion of models integrating candidates already verified as invalid is as high as 93%–100%.71% similarUnverifiedA confidence score given by a model (e.g., 90%) should not be interpreted as 'the model is correct 90% of the time'; accuracy must be empirically measured using your own samples.71% similarUnverifiedThe oracle router knows in advance which cases the small model will get wrong, sends only the wrong requests to the large model, and achieves accuracy comparable to always using the large model at only 29% of the cost.70% similarUnverifiedFeatures driven by large language models may perform excellently in 90% of cases, yet give bizarre responses in the remaining 10% of long-tail scenarios.69% similar
