LlamaIndex Launches Boo Bench to Expose Repetition Loops in Document Parsers

LlamaIndex released Boo Bench, a benchmark of 179 real "trap" pages—dot leaders, all-zero tables, near-identical rows, rare-language scans—that trigger repetition loops in document parsers, with one model emitting 23,000 x's from a page of 246. LlamaIndex's LlamaParse Agentic scored a perfect 179/179, beating frontier VLMs.
