aiqbench analysis
CorporateBench addresses a critical gap in LLM evaluation by introducing a large-scale, human-validated benchmark that simulates realistic corporate communication networks with over 230,000 documents. The study reveals that current models struggle significantly as input size approaches the scale of actual enterprise environments, highlighting limitations in handling temporal knowledge consistency and complex information extraction. This resource provides developers with a necessary metric to assess reasoning capabilities beyond simple synthetic datasets.
CorporateBench: Large-Scale Q&A Benchmarking with Temporal Knowledge Bases
arXiv:2608.27391v1 Announce Type: new Abstract: LLMs are increasingly able to answer complex questions about enterprise-scale document collections. But evaluation is hard: companies don't want to share internal communications, and synthetic datasets have been overly simple. We present CorporateBench (CB), a human-validated multi-task Q&A benchmark whose scale approaches the conditions LLMs encounter in corporate communication networks, with evaluation corpora surpassing 230,000 documents. CB evaluates LLMs across two dimensions (information extraction and knowledge base querying) through four synthetically generated firms ranging from 12 to 10,000 employees. Each corpus is sampled from a temporally evolving knowledge base describing a consistent world, guaranteeing cross-document logical consistency even across hundreds of thousands of documents. We evaluate five LLMs on CB, revealing increasingly poor performance as input size approaches realistic scales. CB provides LLM developers a metric for corporate communication reasoning, filling a crucial gap in the benchmarking ecosystem.
