LlamaIndex Launches ExtractBench: 4,869 Pages of Complex Docs Across 8 Domains
llama_index · x · 2026-08-12
LlamaIndex founder Jerry Liu introduced ExtractBench, a benchmark designed to evaluate information extraction from complex enterprise documents.
Key Features:
- Scale & Diversity: Contains 4,869 pages across 8 real-world domains including finance, energy, healthcare, and legal, covering 67 document types.
- Complex Edge Cases: Includes short to long documents and challenging tables (e.g., tables with over 1k rows, nested tables, cross-page tables), alongside scans, handwriting, and rotated pages.
Evaluation:
The team benchmarked 14 different VLMs, coding agents, and document extraction APIs. Despite recent frontier models pushing the boundaries of coding and knowledge work, they still struggle with complex document extraction in production. A well-tuned extractor must parse multi-page filings without dropping rows, emit exact spatial citations for auditability, and maintain a viable per-page token cost to scale to millions of documents.
