  Evaluating large language models (LLMs) as general-purpose agents is
essential for understanding their capabilities and facilitating their
integration into practical applications. However, the evaluation process
presents substantial challenges. A primary obstacle is the benchmarking of
agent performance across diverse scenarios within a unified framework,
especially in maintaining partially-observable environments and ensuring
multi-round interactions. Moreover, current evaluation frameworks mostly focus
on the final success rate, revealing few insights during the process and
failing to provide a deep understanding of the model abilities. To address
these challenges, we introduce AgentBoard, a pioneering comprehensive benchmark
and accompanied open-source evaluation framework tailored to analytical
evaluation of LLM agents. AgentBoard offers a fine-grained progress rate metric
that captures incremental advancements as well as a comprehensive evaluation
toolkit that features easy assessment of agents for multi-faceted analysis
through interactive visualization. This not only sheds light on the
capabilities and limitations of LLM agents but also propels the
interpretability of their performance to the forefront. Ultimately, AgentBoard
serves as a significant step towards demystifying agent behaviors and
accelerating the development of stronger LLM agents.
