SchemaRouter: Enhancing Heterogeneous Agentic RAG Systems

SchemaRouter introduces a field-aware tool routing system to optimize heterogeneous agentic RAG systems, addressing issues of over-fetching and under-fetching in AI data retrieval.

The system intelligently routes tool descriptions to reduce payload size and latency.

SchemaRouter prevents costly failures by selecting tools based on field awareness rather than vector similarity alone.

This innovation aims to improve the efficiency and accuracy of AI retrieval-augmented generation systems.
