🎯 TokenWise Optimizer

Smart Context Optimization for LLMs - Reduce tokens by 70-90%, save costs, maintain quality.

TokenWise Optimizer analyzes user queries and intelligently ranks context pieces to send only the most relevant information to your LLM, dramatically reducing token usage and costs while maintaining or improving response quality.

📦 PyPI Package: tokenwise-optimizer

✨ Key Features

🎯 Smart Ranking: Multi-method relevance scoring (embeddings, keywords, recency, relationships)
📊 70-90% Token Reduction: Typical reduction without quality loss
⚡ Fast: <500ms optimization overhead
🔄 Multiple Strategies: Top-N, Diversity (MMR), Dependency-aware selection
💾 Vector Store: Optional pre-indexing for faster queries
🗄️ Caching: In-memory caching for repeated queries
📈 Analytics: Track savings, performance, and optimization metrics

🏗️ Architecture

User Query → Analyze Intent → Rank Context Pieces → Select Top N → Send to LLM

Core Components

Context Chunker: Breaks large content into manageable pieces (fixed-size, semantic, sliding window)

📖 API Usage

Optimize Context

Endpoint: POST /optimize

Request:

{
  "query": "How does authentication work?",
  "context": [
    {
      "id": "file1",
      "text": "Your content here...",
      "type": "code"
    }
  ],
  "targetTokens": 4000,
  "options": {
    "strategy": "diversity",
    "includeMetadata": true,
    "preserveOrder": false,
    "minRelevanceScore": 0.3,
    "diversityLambda": 0.5
  }
}

Response:

{
  "optimized_context": [
    {
      "id": "chunk_1",
      "text": "Relevant content...",
      "relevance_score": 0.89,
      "reason": "High semantic similarity + keywords match",
      "source": "file1"
    }
  ],
  "stats": {
    "original_tokens": 50000,
    "optimized_tokens": 3847,
    "reduction_percent": 92.3,
    "estimated_savings_usd": 2.41,
    "processing_time_ms": 387,
    "chunks_analyzed": 45,
    "chunks_selected": 8
  }
}

Index Content (Optional)

Pre-index content for faster future queries:

curl -X POST http://localhost:8000/index \
  -H "Content-Type: application/json" \
  -d '{
    "id": "my_document",
    "text": "Content to index...",
    "type": "docs"
  }'

Health Check

curl http://localhost:8000/health

Statistics

curl http://localhost:8000/stats

🎮 Usage Examples

Basic Python Usage

import requests

response = requests.post(
    "http://localhost:8000/optimize",
    json={
        "query": "How do I authenticate users?",
        "context": [
            {"id": "auth", "text": "...", "type": "code"}
        ],
        "targetTokens": 2000
    }
)

result = response.json()
print(f"Reduced tokens by {result['stats']['reduction_percent']}%")

With Different Strategies

Top-N Selection (Fastest)

options = {"strategy": "top-n"}

Simply takes the highest-scoring chunks. Fast but may miss diversity.

Diversity Selection (Recommended)

options = {
    "strategy": "diversity",
    "diversityLambda": 0.5  # Balance relevance (1.0) vs diversity (0.0)
}

Uses Maximal Marginal Relevance to ensure variety in selected chunks.

Dependency-Aware (Best for Code)

options = {"strategy": "dependency"}

Includes related chunks (e.g., functions that call each other).

📊 Benchmark Results

Real-world performance test with authentication codebase (GPT-3.5-turbo):

Metric	Before TokenWise	After TokenWise	Improvement
Tokens	459	155	66.2% reduction
Cost per query	$0.001288	$0.000772	$0.000516 saved (40%)
Processing time	5.1s	8.7s	+3.5s optimization overhead

Cost Savings at Scale

Queries/Month	Before	After	Monthly Savings
10,000	$12.88	$7.72	$5.16
100,000	$128.80	$77.20	$51.60
1,000,000	$1,288	$772	$516

Query: "How does user authentication and login work?"
Context: 5 files (auth, database, payment, email, analytics)
Selected: Only authentication-related code (1 file)
Ignored: Payment, email, analytics modules (irrelevant)

What This Means

✅ 66% fewer tokens sent to your LLM
✅ Same or better answer quality (focused on relevant code)
✅ Automatic filtering of irrelevant context
✅ $516/month saved at 1M queries (typical enterprise scale)
⚡ Run benchmark: python run_benchmark.py (requires OpenAI API key)

🛠️ Technology Stack

Backend: FastAPI (Python)
Embeddings: OpenAI text-embedding-3-small
Vector DB: ChromaDB
Caching: In-memory (Redis-ready)
Token Counting: tiktoken

📐 How It Works

1. Chunking

Content is split into chunks using:

Fixed-size: Every N tokens
Semantic: At logical boundaries (functions, paragraphs)
Sliding window: Overlapping chunks for continuity

2. Ranking

Each chunk is scored using:

Embedding Similarity (50%): Semantic similarity to query
Keyword Matching (20%): Keyword overlap
Recency (15%): Newer content scores higher
Relationships (10%): Connected chunks are boosted
LLM Scoring (5%): Optional deep analysis

3. Selection

Chunks are selected using:

Top-N: Simple, fast, take highest scores
Diversity (MMR): Balance relevance with variety
Dependency: Include related chunks

4. Assembly

Selected chunks are:

Reordered logically (by source, position)
Formatted with metadata
Returned with statistics

💰 Cost Savings Example

Before TokenWise:

100K tokens per query
1,000 queries/day
Cost: $3/1M tokens
Daily cost: $300

After TokenWise:

10K tokens per query (90% reduction)
1,000 queries/day
Cost: $3/1M tokens
Daily cost: $30

Savings: $270/day = $8,100/month

🎯 Optimization Strategies

When to Use Each Strategy

Strategy	Use Case	Pros	Cons
top-n	Simple queries, speed priority	Fastest, most relevant	May lack diversity
diversity	Complex queries, broad topics	Balanced coverage	Slightly slower
dependency	Code analysis, interconnected data	Complete context	May include less relevant items

Tuning Parameters

targetTokens: Adjust based on your LLM's context window

GPT-3.5: 4,000-8,000 tokens
GPT-4: 8,000-16,000 tokens
Claude: 4,000-8,000 tokens

minRelevanceScore: Filter out low-relevance chunks

Strict: 0.5-0.7
Moderate: 0.3-0.5
Permissive: 0.1-0.3

diversityLambda: Balance relevance vs diversity (for diversity strategy)

High relevance: 0.7-1.0
Balanced: 0.4-0.6
High diversity: 0.0-0.3

🐛 Troubleshooting

"OpenAI API key not configured"

Add OPENAI_API_KEY to .env file

"Could not connect to TokenWise API"

Make sure server is running: python main.py
Check port 8000 is not in use

Slow performance

Pre-index large content with /index endpoint
Reduce target_tokens budget
Use "top-n" strategy instead of "diversity"
Enable Redis for distributed caching

Low quality results

Increase target_tokens budget
Lower minRelevanceScore threshold
Try "diversity" strategy
Check if content is properly chunked
