TOON Format Guides
Master Token-Oriented Object Notation - the efficient data format designed specifically for LLM prompts and AI applications.
Why TOON Format?
TOON (Token-Oriented Object Notation) is a revolutionary data format that reduces token usage by approximately 50% compared to JSON. This translates to significant cost savings when working with LLM APIs like GPT-4, Claude, or other language models.
By using explicit length markers and compact field definitions, TOON maintains readability while maximizing efficiency - perfect for AI applications, chatbot prompts, and data-intensive LLM workflows.
