What is TOON?
TOON (Token-Oriented Object Notation) is a compact representation of JSON data designed to minimize token consumption when using Large Language Models (LLMs). It maintains the full structure and data integrity of JSON while reducing character count through smart optimizations.
Key Optimizations
- Null Compression — null → ~
- Boolean Compression — true/false → T/F
- Unquoted Keys — Remove quotes where safe
- Minimal Whitespace — Remove unnecessary spaces
- Smart String Quoting — Use single quotes when possible
Cost Savings Example
If you're using OpenAI GPT-4 at $0.03 per 1K input tokens, and you send 10MB of JSON context per day:
- Original: ~2,500,000 tokens/day = $75/day
- With TOON (50% reduction): ~1,250,000 tokens/day = $37.50/day
- Monthly savings: ~$1,125
