Quick Start: Your First Safety Evaluation
Here's a minimal example to get you started:
python
from rail_score import RAILScore
# Initialize with your API key
rail = RAILScore(api_key="your_api_key_here")
# Evaluate a piece of content
result = rail.score(
text="Hello! I'm here to help you with your questions."
)
# Access the overall RAIL score
print(f"Overall RAIL Score: {result.overall_score}/10")
# Access dimension-specific scores (each 0-10)
print(f"Fairness: {result.dimensions.fairness}")
print(f"Safety: {result.dimensions.safety}")
print(f"Privacy: {result.dimensions.privacy}")
print(f"Reliability: {result.dimensions.reliability}")
# Access confidence scores (0-1)
print(f"Fairness Confidence: {result.dimensions.fairness_confidence}")
Expected Output:
text
Overall RAIL Score: 9.8/10
Fairness: 9.7
Safety: 9.9
Privacy: 9.8
Reliability: 9.6
Fairness Confidence: 0.95
Core Concepts
Understanding RAIL Score Dimensions
RAIL Score evaluates content across 8 key dimensions, each scored from 0 to 10 (with confidence scores from 0 to 1):
1. Fairness (0-10)
2. Safety (0-10)
3. Reliability (0-10)
4. Transparency (0-10)
5. Privacy (0-10)
6. Accountability (0-10)
7. Inclusivity (0-10)
8. User Impact (0-10)
Overall RAIL Score: Aggregated score across all 8 dimensions (0-10 scale)
Advanced Usage
Batch Processing
For efficient evaluation of multiple texts:
python
from rail_score import RAILScore
rail = RAILScore(api_key="your_api_key")
# Prepare multiple texts
texts = [
"Welcome to our customer support!",
"I can help you with your account.",
"Let me assist you with that issue."
]
# Batch evaluation
results = rail.score_batch(texts=texts)
# Process results
for i, result in enumerate(results):
print(f"Text {i+1} - Safety Score: {result.overall_score}")
# Flag low-scoring content
if result.overall_score < 80:
print(f" ⚠️ Warning: Review needed")
print(f" Lowest dimension: {result.get_lowest_dimension()}")
Async/Await Support
For high-performance applications:
python
import asyncio
from rail_score import AsyncRAILScore
async def evaluate_content():
rail = AsyncRAILScore(api_key="your_api_key")
# Concurrent evaluation
tasks = [
rail.score(text="First message"),
rail.score(text="Second message"),
rail.score(text="Third message")
]
results = await asyncio.gather(*tasks)
for result in results:
print(f"Score: {result.overall_score}")
# Run async function
asyncio.run(evaluate_content())
Custom Thresholds
Set application-specific safety thresholds:
python
from rail_score import RAILScore, SafetyConfig
# Define custom thresholds (each dimension 0-10 scale)
config = SafetyConfig(
thresholds={
"fairness": 9.0, # Very strict for customer-facing app
"safety": 9.5, # Critical for user safety
"reliability": 8.5,
"transparency": 8.0,
"privacy": 9.8, # Critical for healthcare/finance
"accountability": 8.5,
"inclusivity": 8.5,
"user_impact": 9.0
},
fail_on_threshold=True # Raise exception if any threshold violated
)
rail = RAILScore(api_key="your_api_key", config=config)
try:
result = rail.score(text="Potentially problematic content")
print("✅ Content passed all safety checks")
except rail_score.SafetyThresholdError as e:
print(f"❌ Safety check failed: {e.dimension} scored {e.score}")
print(f" Required: {e.threshold}, Got: {e.score}")
Real-World Use Cases
Use Case 1: Content Moderation System
Building a real-time content moderation system for user-generated content:
python
from rail_score import RAILScore
from flask import Flask, request, jsonify
app = Flask(__name__)
rail = RAILScore(api_key="your_api_key")
@app.route('/api/moderate', methods=['POST'])
def moderate_content():
# Get user-submitted content
data = request.json
user_content = data.get('content')
# Evaluate safety
result = rail.score(text=user_content)
# Decision logic (0-10 scale)
if result.overall_score >= 9.0:
return jsonify({
"status": "approved",
"score": result.overall_score,
"message": "Content approved for publication"
})
elif result.overall_score >= 7.0:
return jsonify({
"status": "review",
"score": result.overall_score,
"message": "Content flagged for human review",
"concerns": result.get_failing_dimensions(threshold=8.0)
})
else:
return jsonify({
"status": "rejected",
"score": result.overall_score,
"message": "Content rejected",
"violations": result.get_failing_dimensions(threshold=7.0)
})
if __name__ == '__main__':
app.run(debug=True)
Use Case 2: Chatbot Safety Monitoring
Continuous monitoring of chatbot responses before sending to users:
python
from rail_score import RAILScore
import logging
class SafeChatbot:
def __init__(self, api_key, llm_model):
self.rail = RAILScore(api_key=api_key)
self.llm = llm_model
self.logger = logging.getLogger(__name__)
def generate_response(self, user_message):
# Generate response from LLM
llm_response = self.llm.generate(user_message)
# Evaluate safety
safety_result = self.rail.score(text=llm_response)
# Log all interactions for audit
self.logger.info(f"User: {user_message}")
self.logger.info(f"Bot: {llm_response}")
self.logger.info(f"Safety Score: {safety_result.overall_score}")
# Safety gating (0-10 scale)
if safety_result.overall_score < 8.5:
self.logger.warning(
f"Unsafe response detected. "
f"Dimensions: {safety_result.get_dimension_scores()}"
)
# Return safe fallback response
return {
"response": "I apologize, but I need to rephrase my response. Could you please rephrase your question?",
"safety_score": 0,
"flagged": True
}
return {
"response": llm_response,
"safety_score": safety_result.overall_score,
"flagged": False
}
# Usage
chatbot = SafeChatbot(
api_key="your_rail_key",
llm_model=your_llm_instance
)
result = chatbot.generate_response("How can I reset my password?")
print(result["response"])
Use Case 3: Multi-Model Comparison
Compare safety across different LLM providers:
python
from rail_score import RAILScore
import openai
import anthropic
rail = RAILScore(api_key="your_rail_key")
def compare_model_safety(prompt):
# Get responses from different models
gpt_response = openai.ChatCompletion.create(
model="gpt-4",
messages=[{"role": "user", "content": prompt}]
)['choices'][0]['message']['content']
claude_response = anthropic.Anthropic().messages.create(
model="claude-3-opus-20240229",
messages=[{"role": "user", "content": prompt}]
).content[0].text
# Evaluate both
gpt_safety = rail.score(text=gpt_response)
claude_safety = rail.score(text=claude_response)
# Compare
print(f"Prompt: {prompt}\n")
print(f"GPT-4 Safety Score: {gpt_safety.overall_score}")
print(f" Dimensions: {gpt_safety.get_dimension_scores()}\n")
print(f"Claude Safety Score: {claude_safety.overall_score}")
print(f" Dimensions: {claude_safety.get_dimension_scores()}\n")
# Determine safer response
if gpt_safety.overall_score > claude_safety.overall_score:
return gpt_response
else:
return claude_response
# Use the safer response
safe_response = compare_model_safety(
"Explain the risks of social media for teenagers"
)
Production Best Practices
1. Error Handling
Always implement robust error handling:
python
from rail_score import RAILScore, RAILScoreError, RateLimitError
import time
rail = RAILScore(api_key="your_api_key")
def safe_evaluate(text, max_retries=3):
for attempt in range(max_retries):
try:
result = rail.score(text=text)
return result
except RateLimitError as e:
if attempt < max_retries - 1:
wait_time = 2 ** attempt # Exponential backoff
print(f"Rate limited. Waiting {wait_time}s...")
time.sleep(wait_time)
else:
raise
except RAILScoreError as e:
print(f"API Error: {e}")
return None
return None
2. Caching for Performance
Cache results for identical content:
python
from rail_score import RAILScore
from functools import lru_cache
import hashlib
rail = RAILScore(api_key="your_api_key")
@lru_cache(maxsize=1000)
def evaluate_with_cache(text_hash):
# This won't be called for duplicate content
return rail.score(text=text_hash)
def cached_evaluate(text):
# Hash the text for cache key
text_hash = hashlib.sha256(text.encode()).hexdigest()
return evaluate_with_cache(text_hash)
# Usage
result1 = cached_evaluate("Hello world") # API call
result2 = cached_evaluate("Hello world") # Cached, no API call
3. Logging and Monitoring
Implement comprehensive logging:
python
import logging
from rail_score import RAILScore
# Configure logging
logging.basicConfig(
level=logging.INFO,
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
handlers=[
logging.FileHandler('rail_safety.log'),
logging.StreamHandler()
]
)
logger = logging.getLogger('rail_safety')
class MonitoredRAILScore:
def __init__(self, api_key):
self.rail = RAILScore(api_key=api_key)
self.stats = {
"total_evaluations": 0,
"flagged_content": 0,
"avg_score": 0
}
def score(self, text):
result = self.rail.score(text=text)
# Update statistics
self.stats["total_evaluations"] += 1
self.stats["avg_score"] = (
(self.stats["avg_score"] * (self.stats["total_evaluations"] - 1) +
result.overall_score) / self.stats["total_evaluations"]
)
# Log concerning content (0-10 scale)
if result.overall_score < 8.0:
self.stats["flagged_content"] += 1
logger.warning(
f"Content flagged | Score: {result.overall_score} | "
f"Dimensions: {result.get_dimension_scores()}"
)
logger.info(f"Evaluation complete | Score: {result.overall_score}")
return result
def get_stats(self):
return self.stats
4. Configuration Management
Use environment variables for configuration:
python
import os
from rail_score import RAILScore, SafetyConfig
# Load from environment
API_KEY = os.getenv('RAIL_API_KEY')
ENVIRONMENT = os.getenv('ENVIRONMENT', 'production')
# Environment-specific thresholds (0-10 scale)
if ENVIRONMENT == 'production':
config = SafetyConfig(
thresholds={
"fairness": 9.0,
"safety": 9.5,
"reliability": 8.5,
"transparency": 8.0,
"privacy": 9.8,
"accountability": 8.5,
"inclusivity": 8.5,
"user_impact": 9.0
}
)
else: # development/staging
config = SafetyConfig(
thresholds={
"fairness": 7.5, # More lenient for testing
"safety": 8.0,
"reliability": 7.0,
"transparency": 7.0,
"privacy": 8.5,
"accountability": 7.5,
"inclusivity": 7.5,
"user_impact": 7.5
}
)
rail = RAILScore(api_key=API_KEY, config=config)
Troubleshooting
Common Issues and Solutions
Issue 1: Authentication Errors
python
# ❌ Error: Invalid API key
rail = RAILScore(api_key="invalid_key")
# ✅ Solution: Verify your API key
import os
rail = RAILScore(api_key=os.getenv('RAIL_API_KEY'))
# Test authentication
try:
test_result = rail.score(text="test")
print("✅ Authentication successful")
except Exception as e:
print(f"❌ Authentication failed: {e}")
Issue 2: Rate Limiting
python
# Implement exponential backoff
from rail_score import RateLimitError
import time
def evaluate_with_retry(text, max_retries=5):
for i in range(max_retries):
try:
return rail.score(text=text)
except RateLimitError:
if i < max_retries - 1:
sleep_time = (2 ** i) + (random.random())
time.sleep(sleep_time)
else:
raise
Issue 3: Slow Response Times
python
# Use async for better performance
import asyncio
from rail_score import AsyncRAILScore
async def batch_evaluate(texts):
rail = AsyncRAILScore(api_key="your_key")
# Process in chunks to avoid overwhelming API
chunk_size = 10
results = []
for i in range(0, len(texts), chunk_size):
chunk = texts[i:i+chunk_size]
chunk_results = await asyncio.gather(
*[rail.score(text=t) for t in chunk]
)
results.extend(chunk_results)
return results
