TOKEN-ORIENTED OBJECT NOTATION (TOON)

TOON is a compact, human-readable format designed for LLM input that allows developers to pass structured data to LLMs with significantly reduced token usage. It excels at uniform complex objects. Standard JSON is verbose and token-expensive - TOON conveys the same information with fewer tokens. In benchmark tests, TOON achieves higher accuracy compared to JSON while using significantly fewer tokens.

PDF_OBJECT_HASHING

PDF Object Hash is a method for identifying similarities between PDFs based on their structure rather than content, akin to imphash or ja3 hashes. It involves extracting object types and hashing them to cluster similar documents and detect overlaps. Recent updates to the parsing scripts improve accuracy, especially for irregular or corrupted PDFs.
