Harness-1: 20B Retrieval Subagent Simplifies Search Agent Architecture

Short summary

Harness-1, a 20B retrieval subagent from UIUC researchers, simplifies search agent design by separating query generation, exploration memory, evidence collection, and relevance filtering into modular components. The approach achieves competitive performance with reduced complexity and computational cost compared to monolithic search systems.

• •Separates search agent tasks into modular components for better control and efficiency
• •20B parameter model shows performance competitive with much larger systems
• •Reduces complexity and cost compared to traditional search agent architectures
