SearchSkill: Teaching LLMs to Use Search Tools with Evolving Skill Banks

SearchSkill is a new framework that teaches language models to perform more effective web searches by explicitly planning queries through reusable skill cards rather than treating search as an undifferentiated action. The system maintains an evolving skill bank that improves from failure patterns, demonstrating better performance on knowledge-intensive QA tasks with fewer wasted queries and improved reasoning accuracy.

PiCA: Pivot-Based Credit Assignment for Search Agentic Reinforcement Learning

Researchers introduce PiCA (Pivot-Based Credit Assignment), a novel reinforcement learning mechanism that improves how LLM-based search agents learn from long sequences of actions. By identifying key pivot steps and anchoring rewards to final task outcomes, PiCA addresses critical challenges in credit assignment, delivering 15.2% performance gains on knowledge-intensive QA tasks.

Assessment of RAG and Fine-Tuning for Industrial Question-Answering-Applications

A new study compares Retrieval-Augmented Generation (RAG) and fine-tuning approaches for adapting Large Language Models to enterprise question-answering tasks in the automotive industry. The research finds that RAG offers superior cost-efficiency while maintaining comparable answer quality, even enabling open-source models to match premium model performance.
