Introduction
Are you struggling to get consistent, high-quality responses from your LLM applications? Do you want to systematically optimize your prompts but don't know where to start?
I've built a comprehensive LLM Prompt Optimizer that solves these exact problems. It's an enterprise-ready Python framework that provides A/B testing, real-time analytics, security features, and a complete API for optimizing prompts across multiple LLM providers.
🎯 What You'll Learn
- How to build a systematic approach to prompt optimization
- Implementing A/B testing for LLM prompts with statistical significance
- Adding real-time analytics and monitoring to your AI applications
- Building security features for content safety and bias detection
- Creating enterprise-ready APIs with FastAPI
- Deploying your solution to production
🚀 Key Features
📊 A/B Testing with Statistical Significance
# Create an experiment with multiple prompt variants
experiment = await optimizer.create_experiment(
name="Customer Support Test",
variants=[
{"name": "friendly", "template": "Hi there! I'm here to help: {input}"},
{"name": "professional", "template": "Thank you for contacting us: {input}"}
],
config={"traffic_split": 0.5, "confidence_level": 0.95}
)
🔒 Security & Compliance
- Content Safety: Automatically detect unsafe content
- Bias Detection: Identify and flag biased responses
- Injection Prevention: Protect against prompt injection attacks
- Audit Logging: Complete security audit trails
📈 Real-Time Analytics
- Cost Tracking: Monitor API usage and costs
- Quality Scoring: Automated response quality assessment
- Performance Metrics: Real-time dashboard and monitoring
- Predictive Analytics: Forecast performance trends
🛠️ Technical Architecture
The framework is built with modern Python technologies:
- FastAPI: High-performance API framework
- Pydantic: Data validation and serialization
- SQLAlchemy: Database ORM
- Redis: Caching and session management
- Uvicorn: ASGI server
📦 Installation & Quick Start
1. Install the Package
pip install llm-prompt-optimizer==0.3.0
2. Start the API Server
from prompt_optimizer.api.server import create_app
import uvicorn
app = create_app()
uvicorn.run(app, host="0.0.0.0", port=8000)
3. Create Your First Experiment
import requests
# Create an A/B test experiment
response = requests.post("http://localhost:8000/api/v1/experiments", json={
"name": "Email Subject Line Test",
"variants": [
{
"name": "direct",
"template": "Write a direct email subject line for: {product}",
"parameters": {}
},
{
"name": "curious",
"template": "Write a curiosity-driven email subject line for: {product}",
"parameters": {}
}
],
"config": {
"traffic_split": 0.5,
"min_sample_size": 100,
"confidence_level": 0.95
}
})
🔍 API Endpoints Overview
The framework provides 25+ endpoints across multiple categories:
Experiment Management
-
POST /api/v1/experiments- Create experiments -
GET /api/v1/experiments- List all experiments -
POST /api/v1/experiments/{id}/start- Start experiments
Analytics & Monitoring
-
GET /api/v1/analytics/cost-summary- Cost tracking -
GET /api/v1/monitoring/dashboard- Real-time metrics -
GET /api/v1/analytics/quality-report- Quality assessment
Security Features
-
POST /api/v1/security/check-content- Content safety -
POST /api/v1/security/detect-bias- Bias detection -
GET /api/v1/security/audit-logs- Security logs
🎯 Real-World Use Cases
E-commerce Optimization
# Test different product recommendation prompts
experiment_data = {
"name": "Product Recommendations",
"variants": [
{
"name": "personalized",
"template": "Based on {user_history}, recommend products for {user_id}"
},
{
"name": "trending",
"template": "Recommend trending products similar to {user_interests}"
}
]
}
Customer Support Enhancement
# Optimize customer support responses
support_variants = [
{
"name": "empathetic",
"template": "I understand your concern about {issue}. Let me help you resolve this."
},
{
"name": "solution-focused",
"template": "Here's how we can solve {issue} for you:"
}
]
📊 Analytics & Insights
The framework provides comprehensive analytics:
# Get cost summary
costs = requests.get("http://localhost:8000/api/v1/analytics/cost-summary")
print(f"Total cost: ${costs.json()['data']['total_cost']}")
# Get quality report
quality = requests.get("http://localhost:8000/api/v1/analytics/quality-report")
print(f"Average quality score: {quality.json()['data']['avg_quality_score']}")
🔒 Security Features
Content Safety Check
safety_check = requests.post("http://localhost:8000/api/v1/security/check-content", json={
"content": "Your user-generated content here"
})
if safety_check.json()['data']['is_safe']:
print("Content is safe to use")
else:
print("Content flagged for review")
Bias Detection
bias_check = requests.post("http://localhost:8000/api/v1/security/detect-bias", json={
"text": "Text to check for bias"
})
bias_score = bias_check.json()['data']['bias_score']
print(f"Bias score: {bias_score}")
🚀 Deployment Options
Local Development
python3 start_api_server.py
Production with Docker
docker build -f Dockerfile.rapidapi -t prompt-optimizer-api .
docker run -p 8000:8000 prompt-optimizer-api
RapidAPI Deployment
python3 deploy_rapidapi.py
📈 Performance Metrics
The framework includes comprehensive monitoring:
- Response Time Tracking: Monitor API latency
- Cost Optimization: Track and optimize API usage
- Quality Metrics: Automated response quality assessment
- Statistical Significance: Ensure reliable A/B test results
🎯 Best Practices
1. Start Small
Begin with simple A/B tests on critical user touchpoints.
2. Measure Everything
Track not just response quality, but also user engagement and business metrics.
3. Iterate Quickly
Use the framework's rapid testing capabilities to iterate on prompts.
