Token-based pricing is eating into your AI budget. Every curly brace, quotation mark, and comma in your JSON data costs money. TOON (Token-Oriented Object Notation) eliminates this overhead, delivering 30-60% token reduction across typical LLM workloads. Let's break down exactly how this works and what it means for your bottom line.
Understanding Token-Based Pricing
Before diving into TOON's savings, let's understand the cost model:
Major LLM Providers Pricing (2025)
| Provider | Model | Input Cost | Output Cost |
|---|---|---|---|
| OpenAI | GPT-4 Turbo | $0.01/1K tokens | $0.03/1K tokens |
| OpenAI | GPT-3.5 Turbo | $0.0005/1K tokens | $0.0015/1K tokens |
| Anthropic | Claude 3 Opus | $0.015/1K tokens | $0.075/1K tokens |
| Anthropic | Claude 3 Sonnet | $0.003/1K tokens | $0.015/1K tokens |
| Gemini Pro | $0.00125/1K tokens | $0.00375/1K tokens |
Key Insight: Every token you send or receive costs money. Reducing tokens directly reduces costs.
The Anatomy of Token Waste in JSON
Let's examine where JSON wastes tokens:
Example: Simple User Object
{
"userId": "12345",
"name": "Alice",
"email": "alice@example.com",
"role": "admin"
}
Token Breakdown:
- Opening/closing braces:
{ }= 2 tokens - Quotes around keys:
"userId","name","email","role"= 8 tokens - Quotes around values:
"12345","Alice","alice@example.com","admin"= 8 tokens - Colons:
:= 4 tokens - Commas:
,= 3 tokens - Actual data: 4 keys + 4 values = ~15 tokens
- Overhead: 25 tokens
Total: ~40 tokens (62.5% overhead!)
Same Data in TOON
userId: 12345
name: Alice
email: alice@example.com
role: admin
Token Breakdown:
- Keys: 4 tokens
- Colons: 4 tokens
- Values: 4 tokens
- Line breaks: 3 tokens
- Overhead: 7 tokens
Total: ~15 tokens (47% overhead reduction)
The Five Mechanisms of Token Reduction
1. Elimination of Redundant Syntax
JSON Requirements:
- Curly braces for objects:
{ } - Square brackets for arrays:
[ ] - Quotes around all keys:
"key" - Quotes around string values:
"value" - Commas between items:
,
TOON Approach:
- Indentation replaces braces
- Minimal punctuation
- No quotes on keys
- Context-aware value parsing
Savings: 15-25% token reduction
2. Whitespace Optimization
JSON often includes formatting whitespace:
{
"user": {
"name": "Bob",
"age": 30
}
}
TOON uses meaningful indentation only:
user:
name: Bob
age: 30
Savings: 5-10% token reduction
3. Key-Value Density
JSON's verbosity:
{"firstName": "John", "lastName": "Doe"}
Tokens: ~12
TOON's efficiency:
firstName: John
lastName: Doe
Tokens: ~6
Savings: 50% on simple key-value pairs
4. Nested Structure Efficiency
JSON Nested Object (3 levels deep):
{
"company": {
"department": {
"team": {
"name": "Engineering"
}
}
}
}
Tokens: ~22
TOON Equivalent:
company:
department:
team:
name: Engineering
Tokens: ~10
Savings: 54% for deeply nested structures
5. Array Optimization
JSON Array:
{
"items": [
{"id": 1, "name": "Item A"},
{"id": 2, "name": "Item B"},
{"id": 3, "name": "Item C"}
]
}
Tokens: ~35
TOON Array:
items:
- id: 1
name: Item A
- id: 2
name: Item B
- id: 3
name: Item C
Tokens: ~20
Savings: 43% for object arrays

Factors Affecting Token Reduction
High Reduction Scenarios (50-60%)
Characteristics:
- Deeply nested structures (4+ levels)
- Many small objects
- Repetitive key names
- Large arrays of objects
- Configuration data
Example:
{"config":{"database":{"host":"localhost","port":5432,"credentials":{"user":"admin","pass":"secret"}}}}
Medium Reduction Scenarios (40-50%)
Characteristics:
- Moderate nesting (2-3 levels)
- Mixed data types
- Standard API responses
- Typical CRUD operations
Lower Reduction Scenarios (30-40%)
Characteristics:
- Flat structures
- Large string values
- Binary data representations
- Single-level objects
Beyond Direct Cost Savings
1. Context Window Expansion
Problem: GPT-4 has a 128K token limit
With JSON:
- Fit ~60 typical API responses
With TOON:
- Fit ~100 typical API responses (66% more)
Value: Process more data without pagination or truncation
2. Faster Response Times
JSON Processing:
- More tokens = longer processing time
- Average: 2.5 seconds per request
TOON Processing:
- Fewer tokens = faster processing
- Average: 1.8 seconds per request
Value: 28% faster responses, better user experience
3. Increased API Rate Limits
Many providers limit requests per minute AND tokens per minute.
Example: OpenAI's rate limits
- 3,500 requests/min
- 180,000 tokens/min
With JSON:
- Hit token limit at 360 requests (if each uses 500 tokens)
With TOON:
- Process 720 requests before hitting token limit
Value: 2x effective throughput
4. Reduced Infrastructure Costs
Bandwidth Savings:
- Smaller payloads = less bandwidth
- Especially significant at scale
- Lower CDN costs
Storage Savings:
- Store more data in same space
- Reduce database costs
- Faster backups
Measuring Your Savings
Step 1: Baseline Current Costs
Track for one week:
- Total API requests
- Average tokens per request
- Total monthly spend
Step 2: Sample Conversion
Convert 100 representative samples:
- Measure token reduction percentage
- Average across samples
- Identify outliers
Step 3: Calculate Projected Savings
Monthly Savings = (Current Monthly Cost) × (Avg Token Reduction %)
Annual Savings = Monthly Savings × 12
ROI = Annual Savings / (Implementation Cost)
Step 4: A/B Test in Production
- Run TOON on 10% of traffic
- Compare costs and performance
- Validate projected savings
Implementation ROI Timeline
Week 1-2: Setup and testing
- Convert sample data
- Validate conversion tools
- Test with LLMs
Week 3-4: Pilot deployment

Common Objections Addressed
"Is the savings worth the migration effort?"
For most applications: Absolutely. ROI typically achieved in 2-4 weeks.
"Will it affect response quality?"
No. LLMs process TOON as effectively as JSON. Some users report improved quality due to reduced noise.
"What about ecosystem compatibility?"
Convert at the LLM boundary. Use JSON everywhere else if needed.
"Is TOON production-ready?"
Yes. Multiple tools and libraries available, with growing adoption.
