# Conformal Cascade：多级LLM推理的精度保证新方法

arXiv 新论文提出 Conformal Cascade 框架。在LLM级联推理（小型模型处理简单查询，大型模型处理困难查询）中，现有的置信度阈值方法由于LLM分数校准不准，效果不佳。该框架通过保形预测理论，无需预设数据分布，即可为整体推理结果提供严格的精度保证，有望降低生产环境下的推理成本。

## English Version

**Conformal Cascade: Distribution-Free Accuracy Guarantees for Multi-Tier LLM Inference**

A new arXiv paper introduces Conformal Cascade, a framework that provides distribution-free accuracy guarantees for multi-tier LLM inference. It addresses the miscalibration of LLM confidence scores in cascading systems, offering strict precision guarantees without relying on data distribution assumptions, promising to reduce inference costs in production.
