New algorithm identifies best LLM considering varied query costs

Researchers have developed a novel algorithm for identifying the optimal large language model (LLM) from a group, considering that each LLM has a different cost to query. The algorithm uses "dueling feedback," where pairwise comparisons of model responses provide preference signals, and incorporates heterogeneous sampling costs. This new approach, called Track-and-Stop, is designed to achieve asymptotically optimal cost as error decreases, and has shown consistent improvements over existing cost-unaware and cost-aware methods in evaluations on synthetic and real-world data. AI

IMPACT This research could lead to more efficient and cost-effective selection of LLMs for various applications.

    Cost-Aware Best-LLM Identification using Dueling Feedback

    arXiv:2609.30360v1 Announce Type: cross Abstract: Inspired by the problem of identifying the best model from a collection of large language models (LLMs) with heterogeneous querying costs, we formulate and analyse a variant of the multi-armed bandit (MAB) with (i) dueling feedbac…
