Why use TOON Format?
Token-Oriented Object Notation is built for the AI era.
Save API Costs
Reduces token usage by 15-30% compared to standard JSON. Fewer tokens = lower OpenAI/Anthropic bills.
More Context
By taking up less space, you can fit more data into the limited context window of LLMs.
Human Readable
Unlike binary formats, TOON remains legible and editable by humans.
JSON vs TOON
TOON removes syntactic redundancy (quotes on keys, excessive delimiters) that LLMs don't need to understand structure.
| Standard JSON | TOON Format |
|---|---|
| {"name": "Alice", "age": 25} | name: Alice, age: 25 |
| ["apple", "banana"] | apple banana |
