🚀 Goodbye JSON, Hello TOON — The New Format Designed for AI

A huge update just dropped in the AI world today.

TOON is a new data format built specifically for LLMs — and it might change how we send structured data to models forever.

Why?

Because TOON is:

✅ Lighter than JSON

✅ Faster for LLMs to read

✅ Uses 30–60% fewer tokens

✅ Cheaper for every API call

Instead of repeating {}, "", and field names, TOON compresses your data into a clean schema + CSV-style rows. Example:

JSON Input:
{

"products": [

{ "id": 1, "name": "T-Shirt", "price": 19.99 },

{ "id": 2, "name": "Cap", "price": 14.5 }

]

}

TOON Output:

products[2]{id,name,price}:

1,T-Shirt,19.99

2,Cap,14.5

This simple change saves tokens, reduces costs, and makes agents + RAG systems faster and more reliable.

If you’re building anything that talks to LLMs, TOON might be the new must-use format.

The AI world is moving fast… and today JSON got its first real challenger.
