• Fast Execution: Optimized algorithms for minimal overhead

Example Cost Savings

# Before: 234 tokens = $0.000468 per request
json_str = json.dumps(complex_order)

# After: 127 tokens = $0.000254 per request (46% reduction)
optimized = await brevit.brevity(complex_order)  # Automatic optimization

# Or with explicit configuration
explicit = await brevit.optimize(complex_order)

# Savings: $0.000214 per request
# At 1M requests/month: $214/month savings

Automatic Strategy Selection

brevit now includes the .brevity() method that automatically analyzes your data and selects the optimal optimization strategy:

data = {
    "friends": ["ana", "luis", "sam"],
    "hikes": [
        {"id": 1, "name": "Blue Lake Trail", "distanceKm": 7.5},
        {"id": 2, "name": "Ridge Overlook", "distanceKm": 9.2}
    ]
}

# Automatically detects uniform arrays and applies tabular format
optimized = await brevit.brevity(data)
# No configuration needed - Brevit analyzes and optimizes automatically!

Quick Start

Basic Usage

from brevit import BrevitClient, BrevitConfig, JsonOptimizationMode
import asyncio

async def main():
    # 1. Create configuration
    config = BrevitConfig(
        json_mode=JsonOptimizationMode.Flatten,
        text_mode=TextOptimizationMode.Clean,
        image_mode=ImageOptimizationMode.Ocr,
        long_text_threshold=1000  # Summarize text over 1000 chars
    )

    # 2. Create client
    brevit = BrevitClient(config)

    # 3. Optimize data
    order = {
        "orderId": "o-456",
        "status": "SHIPPED",
        "items": [
            {"sku": "A-88", "name": "Brevit Pro License", "quantity": 1}
        ]
    }

    optimized = await brevit.optimize(order)
    # Result (with abbreviations enabled by default):
    # "@o=order\[e-mail]:o-456\[e-mail]:SHIPPED\[e-mail][1]{name,quantity,sku}:\nBrevit Pro License,1,A-88"
    print(optimized)

asyncio.run(main())

Abbreviation Feature (New in v0.1.2)

Brevit automatically creates abbreviations for frequently repeated prefixes, reducing token usage by 10-25%:

from brevit import BrevitClient, BrevitConfig, JsonOptimizationMode

config = BrevitConfig(
    json_mode=JsonOptimizationMode.Flatten,
    enable_abbreviations=True,    # Enabled by default
    abbreviation_threshold=2           # Minimum occurrences to abbreviate
)
brevit = BrevitClient(config)

data = {
    "user": {
        "name": "John Doe",
        "email": "[e-mail]",
        "age": 30
    },
    "order": {
        "id": "o-456",
        "status": "SHIPPED"
    }
}

optimized = await brevit.brevity(data)
# Output with abbreviations:
# @u=user
# @o=order
# @u.name:John Doe
# @u.email:[e-mail]
# @u.age:30
# @o.id:o-456
# @o.status:SHIPPED

Token Savings: The abbreviation feature reduces tokens by replacing repeated prefixes like "user." and "order." with short aliases like "@u" and "@o", saving 10-25% on typical nested JSON structures.

Complete Usage Examples

brevit supports three main data types: JSON objects/strings, text files/strings, and images. Here's how to use each:

1. JSON Optimization Examples

Example 1.1: Simple JSON Object

from brevit import BrevitClient, BrevitConfig, JsonOptimizationMode

brevit = BrevitClient(BrevitConfig(json_mode=JsonOptimizationMode.Flatten))

data = {
    "user": {
        "name": "John Doe",
        "email": "[e-mail]",
        "age": 30
    }
}

# Method 1: Automatic optimization (recommended)
optimized = await brevit.brevity(data)
# Output (with abbreviations enabled by default):
# @u=user
# @u.name:John Doe
# @u.email:[e-mail]
# @u.age:30

# Method 2: Explicit optimization
explicit = await brevit.optimize(data)

Example 1.2: JSON String

json_string = '{"order": {"id": "o-456", "status": "SHIPPED"}}'

# Brevit automatically detects JSON strings
optimized = await brevit.brevity(json_string)
# Output (with abbreviations enabled by default):
# @o=order
# @o.id:o-456
# @o.status:SHIPPED

Example 1.3: Complex Nested JSON with Arrays

complex_data = {
    "context": {
        "task": "Our favorite hikes together",
        "location": "Boulder",
        "season": "spring_2025"
    },
    "friends": ["ana", "luis", "sam"],
    "hikes": [
        {
            "id": 1,
            "name": "Blue Lake Trail",
            "distanceKm": 7.5,
            "elevationGain": 320,
            "companion": "ana",
            "wasSunny": True
        },
        {
            "id": 2,
            "name": "Ridge Overlook",
            "distanceKm": 9.2,
            "elevationGain": 540,
            "companion": "luis",
            "wasSunny": False
        }
    ]
}

optimized = await brevit.brevity(complex_data)
# Output (with abbreviations enabled by default):
# @c=context
# @c.task:Our favorite hikes together
# @c.location:Boulder
# @c.season:spring_2025
# friends[3]:ana,luis,sam
# hikes[2]{companion,distanceKm,elevationGain,id,name,wasSunny}:
# ana,7.5,320,1,Blue Lake Trail,True
# luis,9.2,540,2,Ridge Overlook,False

Example 1.4: Different JSON Optimization Modes

# Flatten Mode (Default)
flatten_config = BrevitConfig(json_mode=JsonOptimizationMode.Flatten)
# Converts nested JSON to flat key-value pairs

# YAML Mode
yaml_config = BrevitConfig(json_mode=JsonOptimizationMode.ToYaml)
# Converts JSON to YAML format (requires PyYAML)

# Filter Mode
filter_config = BrevitConfig(
    json_mode=JsonOptimizationMode.Filter,
    json_paths_to_keep=["user.name", "order.id"]
)
# Keeps only specified paths, removes everything else

2. Text Optimization Examples

Example 2.1: Long Text String

long_text = "This is a very long document..." * 100

config = BrevitConfig(
    json_mode=JsonOptimizationMode.None,
    text_mode=TextOptimizationMode.Clean,
    long_text_threshold=500
)
brevit = BrevitClient(config)

# Automatic detection
optimized = await brevit.brevity(long_text)

# Explicit text optimization
cleaned = await brevit.optimize(long_text)

Example 2.2: Reading Text from File

# Read text file
with open('document.txt', 'r', encoding='utf-8') as f:
    text_content = f.read()

# Optimize the text
optimized = await brevit.brevity(text_content)

Example 2.3: Text Optimization Modes

# Clean Mode (Remove Boilerplate)
clean_config = BrevitConfig(text_mode=TextOptimizationMode.Clean)
# Removes signatures, headers, repetitive content

# Summarize Fast
fast_config = BrevitConfig(text_mode=TextOptimizationMode.SummarizeFast)
# Fast summarization (requires custom text optimizer implementation)

# Summarize High Quality
quality_config = BrevitConfig(text_mode=TextOptimizationMode.SummarizeHighQuality)
# High-quality summarization (requires custom text optimizer with LLM integration)

3. Image Optimization Examples

Example 3.1: Image from File (OCR)

# Read image file
with open('receipt.jpg', 'rb') as f:
    image_bytes = f.read()

# Brevit automatically detects bytes as image data
extracted_text = await brevit.brevity(image_bytes)
# Output: OCR-extracted text from the image

Example 3.2: Image from URL

import requests

# Fetch image from URL
response = requests.get('https://example.com/invoice.png')
image_bytes = response.content

# Optimize image
extracted_text = await brevit.brevity(image_bytes)

Example 3.3: Image Optimization Modes

# OCR Mode (Extract Text)
ocr_config = BrevitConfig(image_mode=ImageOptimizationMode.Ocr)
# Extracts text from images using OCR (requires custom image optimizer)

# Metadata Mode
metadata_config = BrevitConfig(image_mode=ImageOptimizationMode.Metadata)
# Extracts only image metadata (dimensions, format, etc.)

4. Method Comparison: .brevity() vs .optimize()

.brevity() - Automatic Strategy Selection

Use when: You want Brevit to automatically analyze and select the best optimization strategy.

# Automatically detects data type and applies optimal strategy
result = await brevit.brevity(data)
# - JSON objects → Flatten with tabular optimization
# - Long text → Text optimization
# - Images → OCR extraction

Advantages:

• Zero configuration needed
• Intelligent strategy selection
• Works with any data type
• Best for general-purpose use

.optimize() - Explicit Configuration

Use when: You want explicit control over optimization mode.

config = BrevitConfig(
    json_mode=JsonOptimizationMode.Flatten,
    text_mode=TextOptimizationMode.Clean,
    image_mode=ImageOptimizationMode.Ocr
)
brevit = BrevitClient(config)

# Uses explicit configuration
result = await brevit.optimize(data)

Advantages:

• Full control over optimization
• Predictable behavior
• Best for specific use cases

5. Custom Optimizers

You can provide custom optimizers for text and images:

# Custom text optimizer
class CustomTextOptimizer:
    async def optimize_text(self, text: str, config: BrevitConfig) -> str:
        # Call your summarization service
        return await summarize_service.summarize(text)

# Custom image optimizer
class CustomImageOptimizer:
    async def optimize_image(self, image_data: bytes, config: BrevitConfig) -> str:
        # Call your OCR service (e.g., Azure AI Vision, Tesseract)
        return await ocr_service.extract_text(image_data)

brevit = BrevitClient(
    config,
    text_optimizer=CustomTextOptimizer(),
    image_optimizer=CustomImageOptimizer()
)

6. Complete Workflow Examples

Example 6.1: E-Commerce Order Processing

# Step 1: Optimize order JSON
order = {
    "orderId": "o-456",
    "customer": {"name": "John", "email": "[e-mail]"},
    "items": [
        {"sku": "A-88", "quantity": 2, "price": 29.99},
        {"sku": "B-22", "quantity": 1, "price": 49.99}
    ]
}

optimized_order = await brevit.brevity(order)

# Step 2: Send to LLM
prompt = f"Analyze this order:\n\n{optimized_order}\n\nExtract total amount."
# Send prompt to OpenAI, Anthropic, etc.

Example 6.2: Document Processing Pipeline

# Step 1: Read and optimize text document
with open('contract.txt', 'r') as f:
    contract_text = f.read()

optimized_text = await brevit.brevity(contract_text)

# Step 2: Process with LLM
prompt = f"Summarize this contract:\n\n{optimized_text}"
# Send to LLM for summarization

Example 6.3: Receipt OCR Pipeline

# Step 1: Read receipt image
with open('receipt.jpg', 'rb') as f:
    receipt_image = f.read()

# Step 2: Extract text via OCR
extracted_text = await brevit.brevity(receipt_image)

# Step 3: Optimize extracted text (if it's long)
optimized = await brevit.brevity(extracted_text)

# Step 4: Send to LLM for analysis
prompt = f"Extract items and total from this receipt:\n\n{optimized}"
# Send to LLM

Flask/FastAPI Example

from flask import Flask, request, jsonify
from brevit import BrevitClient, BrevitConfig, JsonOptimizationMode

app = Flask(__name__)

# Initialize Brevit client

Advanced Usage

Custom Text Optimizer

Implement ITextOptimizer to use LangChain or your own LLM service:

from brevit import ITextOptimizer, BrevitConfig
from langchain.llms import OpenAI
from langchain.chains import LLMChain
from langchain.prompts import PromptTemplate

class LangChainTextOptimizer:
    def __init__(self):
        self.llm = OpenAI(temperature=0)
        self.prompt = PromptTemplate(
            input_variables=["text"],
            template="Summarize the following text: {text}"
        )
        self.chain = LLMChain(llm=self.llm, prompt=self.prompt)

    async def optimize_text(self, long_text: str, config: BrevitConfig) -> str:
        result = await self.chain.arun(text=long_text)
        return result

# Use custom optimizer
config = BrevitConfig(text_mode=TextOptimizationMode.SummarizeFast)
brevit = BrevitClient(config, text_optimizer=LangChainTextOptimizer())

Custom Image Optimizer

Implement IImageOptimizer to use Azure AI Vision or Tesseract:

from brevit import IImageOptimizer, BrevitConfig
from azure.ai.vision.imageanalysis import ImageAnalysisClient
from azure.core.credentials import AzureKeyCredential

class AzureVisionImageOptimizer:
    def __init__(self, endpoint: str, key: str):
        self.client = ImageAnalysisClient(
            endpoint=endpoint,
            credential=AzureKeyCredential(key)
        )

    async def optimize_image(self, image_data: bytes, config: BrevitConfig) -> str:
        result = self.client.analyze(
            image_data=image_data,
            visual_features=["read"]
        )
        return result.read.text

# Use custom optimizer
config = BrevitConfig(image_mode=ImageOptimizationMode.Ocr)
brevit = BrevitClient(
    config,
    image_optimizer=AzureVisionImageOptimizer(endpoint="...", key="...")
)

Using Tesseract OCR

from brevit import IImageOptimizer, BrevitConfig
from PIL import Image
import pytesseract
import io

class TesseractImageOptimizer:
    async def optimize_image(self, image_data: bytes, config: BrevitConfig) -> str:
        image = Image.open(io.BytesIO(image_data))
        text = pytesseract.image_to_string(image)
        return text

config = BrevitConfig(image_mode=ImageOptimizationMode.Ocr)
brevit = BrevitClient(config, image_optimizer=TesseractImageOptimizer())

YAML Mode

To use YAML mode, install PyYAML:

pip install PyYAML

Then update the ToYaml case in brevit.py:

import yaml

# In the optimize method:
elif mode == JsonOptimizationMode.ToYaml:
    return yaml.dump(input_object)

Filter Mode

Use Filter mode to keep only specific JSON paths:

config = BrevitConfig(
    json_mode=JsonOptimizationMode.Filter,
    json_paths_to_keep=[
        "user.name",
        "order.orderId",
        "order.items[*].sku"
    ]
)

Examples

Example 1: Optimize Complex Object

user = {
    "id": "u-123",
    "name": "Javian",
    "isActive": True,
    "contact": {
        "email": "[e-mail]",
        "phone": None
    },
    "orders": [
        {"orderId": "o-456", "status": "SHIPPED"}
    ]
}

optimized = await brevit.optimize(user)
# Output (with abbreviations enabled by default):
# @c=contact
# @o=orders
# id:u-123
# name:Javian
# isActive:True
# @c.email:[e-mail]
# @c.phone:None
# @o[0].orderId:o-456
# @o[0].status:SHIPPED

Example 2: Optimize JSON String

json_str = """{
    "order": {
        "orderId": "o-456",
        "status": "SHIPPED",
        "items": [
            {"sku": "A-88", "name": "Brevit Pro", "quantity": 1}
        ]
    }
}"""

optimized = await brevit.optimize(json_str)

Example 3: Process Long Text

with open("document.txt", "r") as f:
    long_document = f.read()

optimized = await brevit.optimize(long_document)
# Will trigger text optimization if length > long_text_threshold

Example 4: Process Image

with open("receipt.jpg", "rb") as f:
    image_data = f.read()

optimized = await brevit.optimize(image_data)
# Will trigger image optimization

When Not to Use brevit

Consider alternatives when:

1. API Responses: If returning JSON to HTTP clients, use standard JSON
2. Data Contracts: When strict JSON schema validation is required
3. Small Objects: Objects under 100 tokens may not benefit significantly
4. Real-Time APIs: For REST APIs serving JSON, standard formatting is better
5. Database Storage: Databases expect standard JSON format

Best Use Cases:

• ✅ LLM prompt optimization
• ✅ Reducing OpenAI/Anthropic API costs
• ✅ Processing large datasets for AI
• ✅ Document summarization workflows
• ✅ OCR and image processing pipelines
• ✅ LangChain integrations

Format Overview

Flattened Format (Hybrid Optimization)

Brevit intelligently converts Python dictionaries to flat key-value pairs with automatic tabular optimization:

Input:

order = {
    "orderId": "o-456",
    "friends": ["ana", "luis", "sam"],
    "items": [
        {"sku": "A-88", "quantity": 1},
        {"sku": "T-22", "quantity": 2}
    ]
}

Output (with tabular optimization and abbreviations enabled by default):

orderId: o-456
friends[3]: ana,luis,sam
@i=items
@i[2]{quantity,sku}:
1,A-88
2,T-22

Output (with abbreviations disabled):

orderId: o-456
friends[3]: ana,luis,sam
items[2]{quantity,sku}:
1,A-88
2,T-22

For non-uniform arrays (fallback):

mixed = {
    "items": [
        {"sku": "A-88", "quantity": 1},
        "special-item",
        {"sku": "T-22", "quantity": 2}
    ]
}

Output (fallback to indexed format):

items[0].sku: A-88
items[0].quantity: 1
items[1]: special-item
items[2].sku: T-22
items[2].quantity: 2

Key Features

• Dictionary Keys: Uses Python dictionary keys as-is
• Nested Dicts: Dot notation for nested dictionaries
• Tabular Arrays: Uniform object arrays automatically formatted in compact tabular format (items[2]{field1,field2}:)
• Primitive Arrays: Comma-separated format (friends[3]: ana,luis,sam)
• Abbreviation System (Default: Enabled): Automatically creates short aliases for repeated prefixes (@u=user, @o=order)
• Hybrid Approach: Automatically detects optimal format, falls back to indexed format for mixed data
• None Handling: Explicit None values
• Type Preservation: Numbers, booleans preserved as strings

Abbreviation System (Default: Enabled)

Brevit automatically creates abbreviations for frequently repeated key prefixes, placing definitions at the top of the output:

Example:

@u=user
@o=order
@u.name:John Doe
@u.email:[e-mail]
@o.id:o-456
@o.status:SHIPPED

Benefits:

• 10-25% additional token savings on nested data
• Self-documenting: Abbreviations are defined at the top
• LLM-friendly: Models easily understand the mapping
• Configurable: Can be disabled with enable_abbreviations=False

When Abbreviations Help Most:

• Deeply nested JSON structures
• Arrays of objects with repeated field names
• API responses with consistent schemas
• Data with many repeated prefixes (e.g., user.profile.settings.theme)

Disable Abbreviations:

config = BrevitConfig(
    enable_abbreviations=False  # Disable abbreviation feature
)

API

BrevitClient

Main client class for optimization.

class BrevitClient:
    def __init__(
        self,
        config: BrevitConfig,
        text_optimizer: Optional[ITextOptimizer] = None,
        image_optimizer: Optional[IImageOptimizer] = None,
    ):
    
    # Automatic optimization - analyzes data and selects best strategy
    async def brevity(self, raw_data: Any, intent: Optional[str] = None) -> str:
    
    # Explicit optimization with configured settings
    async def optimize(self, raw_data: Any, intent: Optional[str] = None) -> str:
    
    # Register custom optimization strategy
    def register_strategy(self, name: str, analyzer: Any, optimizer: Any) -> None:

Example - Automatic Optimization:

# Automatically analyzes data structure and selects best strategy
optimized = await brevit.brevity(order)
# Automatically detects uniform arrays, long text, etc.

Example - Explicit Optimization:

# Use explicit configuration
optimized = await brevit.optimize(order, "extract_total")

Example - Custom Strategy:

# Register custom optimization strategy
brevit.register_strategy('custom', custom_analyzer, custom_optimizer)

Using brevit in LLM Prompts

Best Practices

1. Context First: Provide context before optimized data
2. Clear Instructions: Tell the LLM what format to expect
3. Examples: Include format examples in prompts

Example Prompt Template

optimized = await brevit.optimize(order)

prompt = f"""You are analyzing order data. The data is in Brevit flattened format:

Context:
{optimized}

Task: Extract the order total and shipping address.

Format your response as JSON with keys: total, address"""

Real-World Example

async def analyze_order(order: dict):
    optimized = await brevit.optimize(order)
    
    prompt = f"""Analyze this order:

{optimized}

Questions:
1. What is the order total?
2. How many items?
3. Average item price?

Respond in JSON."""
    
    # Call OpenAI API
    response = await openai.ChatCompletion.acreate(
        model="gpt-4",
        messages=[{"role": "user", "content": prompt}]
    )
    
    return response.choices[0].message.content

Syntax Cheatsheet

Python to Brevit Format

Python Structure	Brevit Format	Example
Dictionary key	key: value	orderId: o-456
Nested key	parent.child: value	customer.name: John
Primitive list	list[count]: val1,val2,val3	friends[3]: ana,luis,sam
Uniform object list	list[count]{field1,field2}: val1,val2 val3,val4	items[2]{sku,qty}: A-88,1 T-22,2
List element (fallback)	list[index].key: value	items[0].sku: A-88
Nested list	parent[index].child[index]	orders[0].items[1].sku
None value	key: None	phone: None
Boolean	key: True	isActive: True
Number	key: 123	quantity: 5

Special Cases

• Empty Lists: items: [] → items: []
• Empty Dicts: metadata: {} → metadata: {}
• None: Explicit None values
• Datetime: Converted to ISO string
• Tabular Arrays: Automatically detected when all dicts have same keys
• Primitive Arrays: Automatically detected when all elements are primitives

Other Implementations

Brevit is available in multiple languages:

Language	Package	Status
Python	brevit	✅ Stable (This)
C# (.NET)	Brevit	✅ Stable
JavaScript	brevit	✅ Stable

Full Specification

Format Specification

1. Key-Value Pairs: One pair per line
2. Separator: : (colon + space)
3. Key Format: Dictionary keys with dot/bracket notation
4. Value Format: String representation of values
5. Line Endings: \n (newline)

Grammar

brevit := line*
line := key ": " value "\n"
key := identifier ("." identifier | "[" number "]")*
value := string | number | boolean | None
identifier := [a-zA-Z_][a-zA-Z0-9_]*

Examples

Simple Dict:

orderId: o-456
status: SHIPPED

Nested Dict:

customer.name: John Doe
customer.email: [e-mail]

List:

items[0].sku: A-88
items[0].quantity: 1
items[1].sku: T-22
items[1].quantity: 2

Complex Structure:

orderId: o-456
customer.name: John Doe
items[0].sku: A-88
items[0].price: 29.99
items[1].sku: T-22
items[1].price: 39.99
shipping.address.street: 123 Main St
shipping.address.city: Toronto

Performance Considerations

• Flatten Mode: Reduces token count by 40-60% compared to standard JSON
• Async/Await: All operations are asynchronous for better scalability
• Memory Efficient: Processes data in-place where possible
• Type Hints: Full type annotations for better performance with type checkers

Best Practices

1. Use Async/Await: Always use await when calling optimize()
2. Implement Custom Optimizers: Replace default stubs with real LLM integrations
3. Configure Thresholds: Adjust long_text_threshold based on your use case
4. Monitor Token Usage: Track token counts before/after optimization
5. Error Handling: Wrap optimize calls in try-except blocks
6. Use Type Hints: Leverage type hints for better IDE support

Troubleshooting

Issue: "ToYaml mode requires 'pip install PyYAML'"

Solution: Install PyYAML: pip install PyYAML and update the code as shown in Advanced Usage.

Issue: Text summarization returns stub

Solution: Implement a custom ITextOptimizer using LangChain, Semantic Kernel, or your LLM service (see Advanced Usage).

Issue: Image OCR returns stub

Solution: Implement a custom IImageOptimizer using Azure AI Vision, Tesseract, or your OCR service (see Advanced Usage).

Issue: "Filter mode is not implemented"

Solution: Install jsonpath-ng and implement JSON path filtering logic.
