BEST-Route: Adaptive LLM Routing with Test-Time Optimal Compute

ICML 2025poster

Large language models (LLMs) are powerful tools but are often expensive to deploy at scale. LLM query routing mitigates this by dynamically assigning queries to models of varying cost and quality to obtain a desired tradeoff. Prior query routing approaches generate only one response from the select…

Why Prompt Design Matters and Works: A Complexity Analysis of Prompt Search Space in LLMs

ACL 2025long

Despite the remarkable successes of Large Language Models (LLMs), the underlying Transformer architecture has inherent limitations in handling complex reasoning tasks. Chain-of-Thought (CoT) prompting has emerged as a practical workaround, but most CoT-based methods rely on a single generic prompt l…

Hybrid LLM: Cost-Efficient and Quality-Aware Query Routing

ICLR 2024poster

Large language models (LLMs) excel in most NLP tasks but also require expensive cloud servers for deployment due to their size, while smaller models that can be deployed on lower cost (e.g., edge) devices, tend to lag behind in terms of response quality. Therefore in this work we propose a hybrid in…

LLM Performance Predictors are good initializers for Architecture Search

ACL 2024findings

In this work, we utilize Large Language Models (LLMs) for a novel use case: constructing Performance Predictors (PP) that estimate the performance of specific deep neural network architectures on downstream tasks. We create PP prompts for LLMs, comprising (i) role descriptions, (ii) instructions for…
