Implementation

Install Toonify

pip install toonify

Convert Data to TOON

from toon import encode, decode
import json

# Your structured data
data = {
    "products": [
        {"id": 1, "name": "Laptop", "price": 1299, "stock": 45},
        {"id": 2, "name": "Mouse", "price": 79, "stock": 120},
    ]
}

# Convert to TOON format
toon_str = encode(data)
print(f"JSON: {len(json.dumps(data))} bytes")
print(f"TOON: {len(toon_str)} bytes")

Send to LLM

from openai import OpenAI

client = OpenAI()

# Use TOON format in prompt
response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{
        "role": "user",
        "content": f"Analyze this product data:\n\n{toon_str}"
    }]
)

print(response.choices[0].message.content)

Decode if Needed

# Convert back to Python objects
original_data = decode(toon_str)
assert original_data == data  # Roundtrip verification

Real-World Example

E-commerce Product Analysis

from toon import encode
from openai import OpenAI
import json

client = OpenAI()

# Sample product catalog (could be 100s of products)
products = [
    {"id": 1, "name": "Laptop Pro", "price": 1299, "stock": 45, "category": "Electronics"},
    {"id": 2, "name": "Magic Mouse", "price": 79, "stock": 120, "category": "Accessories"},
    {"id": 3, "name": "USB-C Hub", "price": 49, "stock": 200, "category": "Accessories"},
    {"id": 4, "name": "4K Monitor", "price": 599, "stock": 30, "category": "Electronics"},
    {"id": 5, "name": "Keyboard", "price": 129, "stock": 85, "category": "Accessories"},
    # ... potentially hundreds more
]

# Measure token reduction
json_str = json.dumps(products)
toon_str = encode(products)

print(f"JSON size: {len(json_str)} bytes")
print(f"TOON size: {len(toon_str)} bytes")
print(f"Reduction: {((len(json_str) - len(toon_str)) / len(json_str) * 100):.1f}%")

# Send optimized data to LLM
response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{
        "role": "user",
        "content": f"""
        Analyze this product catalog and provide:
        1. Total inventory value
        2. Low stock items (< 50 units)
        3. Average price by category
        
        Data:
        {toon_str}
        """
    }]
)

print(response.choices[0].message.content)

Results:

JSON: 487 bytes, ~165 tokens
TOON: 186 bytes, ~68 tokens
Reduction: 58.8% tokens, 61.8% bytes

Best Use Cases

Tabular Data

Optimal for:

Product catalogs
CSV exports
Database query results
API response data
Survey results
Analytics data

Token savings: 60-73%

Structured JSON

Good for:

Configuration files
Uniform object arrays
API payloads
Log data

Token savings: 50-65%

When NOT to Use

Avoid TOON for:

Highly nested data (greater than 3 levels)
Irregular/heterogeneous structures
Small payloads (less than 100 bytes)
Binary data
When JSON compatibility is critical

Headroom Context Optimization

Reduce token usage by 47-92% through intelligent context compression for AI agents

What is Headroom?

Headroom is a context optimization layer that compresses tool outputs and conversation history while preserving accuracy. Unlike simple truncation, it uses statistical analysis to keep what matters.

Key Benefits

47-92% Token Reduction

Verified across production workloads

Zero Code Changes

Transparent proxy integration

Reversible Compression

LLM can retrieve original data via CCR

Provider Caching

Optimizes for OpenAI/Anthropic caching

Core Features

SmartCrusher
CacheAligner
CCR System

Statistical Compression

Keeps:

First N items (context)
Last N items (recency)
Anomalies (statistical outliers)
Query-relevant matches

Removes:

Repetitive boilerplate
Redundant middle sections
Low-information content

from headroom import SmartCrusher

crusher = SmartCrusher(
    keep_first=2,
    keep_last=2,
    keep_anomalies=True,
    compression_ratio=0.3
)

# Compress tool output
compressed = crusher.compress(tool_output)

Prefix Optimization

Stabilizes message prefixes for better provider-side caching:

from headroom import CacheAligner

aligner = CacheAligner(provider="anthropic")

# Optimize for cache hits
optimized_messages = aligner.align(messages)

Cache hit rate improvement:

OpenAI: 35% → 78%
Anthropic: 42% → 85%

Compress-Cache-Retrieve

Reversible compression:

Compress: Reduce tokens
Cache: Store original
Retrieve: LLM requests if needed

from headroom import CCR

ccr = CCR()

# Compress with retrieval capability
compressed, cache_id = ccr.compress(large_content)

# LLM can request original
if llm_needs_more_detail:
    original = ccr.retrieve(cache_id)

Installation & Setup

Needle in Haystack Test

Complete Test Results

Setup:

100 production log entries
1 critical FATAL error at position 67
Question: “What caused the outage? Error code? Fix?”

Baseline (no compression):

Tokens: 10,144
Cost: $0.30
Response time: 4.8s
Answer: ✅ Correct (payment-gateway, PG-5523, increase max_connections)

With Headroom:

Tokens: 1,260 (87.6% reduction)
Cost: $0.04 (86.7% savings)
Response time: 1.2s (75% faster)
Answer: ✅ Correct (same details)

What Headroom kept:

Position 67: FATAL error (the needle)
Position 1-2: Context (timeline start)
Position 99-100: Most recent state
Position 45: Anomaly (connection spike)

What Headroom removed:

96 INFO/DEBUG entries
Repetitive health checks
Standard operational logs

Result: Same accuracy, 87.6% fewer tokens
