New benchmark GraphEcho probes LLM agents' evidence-gathering skills

Researchers have introduced GraphEcho, a new benchmark designed to evaluate Large Language Model (LLM) agents' ability to distinguish between genuine evidence and redundant information. The benchmark systematically varies the number of paths an agent follows and the origin of the evidence, while keeping the content of the evidence constant. Experiments show that while provenance-aware post-training can reduce repetitive exploration, it may also lead to a decline in accuracy on scientific claims, highlighting a tension between efficient exploration and effective evidence utilization in LLM agents.

    GraphEcho: Structural Redundancy and Evidence Provenance in LLM Graph Agents

    arXiv:2609.17695v1 Announce Type: new Abstract: A large language model (LLM) agent can follow more graph paths without acquiring more independent evidence. GraphEcho tests whether agents mistake these repeated encounters for additional corroboration. The benchmark varies path cou…
