A new research paper explores the effectiveness of performance prediction in routing queries to different large language models (LLMs). The study demonstrates that performance prediction is most beneficial when the candidate model is suboptimal for a given task or when the predictor significantly enhances the model's capacity. The research proposes that a predictor's advantage over a model's self-confidence can be transferred to improve the model's loss, particularly through recalibration. Experiments with 16 language models indicate that the gains from performance prediction are more pronounced with less optimal models and decrease as models undergo fine-tuning. AI
IMPACT This research could lead to more efficient and cost-effective LLM deployment by optimizing model selection for specific queries.
