New AgentHop benchmark reveals distinct LLM agent behavior patterns

A new diagnostic benchmark called AgentHop has been introduced to evaluate the multi-hop question-answering capabilities of agentic large language models. AgentHop utilizes a controlled seven-tool sandbox with resource constraints to dissect model performance across retrieval, synthesis, tool-call, and resource management. Analysis of 19 models revealed distinct behavioral patterns among different model families, such as GPT models committing early and Anthropic models verifying before committing. The benchmark also highlighted nuanced differences within families, like Claude Opus 4.6 and Sonnet 4.6, which achieved similar overall accuracy but differed in their emphasis on retrieval versus synthesis.

IMPACT Provides a new diagnostic tool for researchers to identify and address failure modes in LLM agents, potentially accelerating improvements in agentic AI capabilities.

    AgentHop: A Diagnostic Benchmark for Agentic Multi-Hop Question Answering over Scientific Citation Graphs

    arXiv:2609.34428v2 Announce Type: replace Abstract: Agentic tasks require a large language model to interact with the world, navigating information and gathering evidence across multiple steps with restricted resources. Due to this complexity, agentic task failures arise from var…
