Aligning Compound AI Systems via System-level DPO

Researchers introduce SysDPO, a framework that extends Direct Preference Optimization to align compound AI systems comprising multiple interacting components like LLMs, foundation models, and external tools. The approach addresses challenges in optimizing complex AI systems by modeling them as Directed Acyclic Graphs and enabling system-level alignment through two variants: SysDPO-Direct and SysDPO-Sampling.

Scaling Retrieval Augmented Generation with RAG Fusion: Lessons from an Industry Deployment

Research on production RAG systems reveals that retrieval fusion techniques like multi-query retrieval and reciprocal rank fusion increase raw document recall but fail to improve end-to-end performance due to re-ranking limits and context constraints. The study found fusion variants actually decreased accuracy from 0.51 to 0.48 while adding latency overhead without corresponding benefits.
