Code Analysis & Refactoring Summary

📊 Code Quality Analysis

✅ Strengths

1. Clean Architecture

   • Well-separated concerns (council logic, API client, storage)
   • Clear 3-stage pipeline design
   • Async/await properly implemented

2. Good Gradio Integration

   • Progressive UI updates with streaming
   • MCP server capability enabled
   • User-friendly progress indicators

3. Solid Core Logic

   • Parallel model querying for efficiency
   • Anonymous ranking system to reduce bias
   • Structured synthesis approach

⚠️ Issues Found

2. Missing Error Handling

   • No retry logic for failed API calls
   • Timeouts not configurable
   • Silent failures in parallel queries

3. Limited Configuration

   • Hardcoded timeouts
   • No alternative model configs
   • Missing environment validation

4. No Dependencies File

   • Missing requirements.txt
   • Unclear Python version requirements

5. Incomplete Documentation

🔄 Refactoring Completed

1. Created requirements.txt

gradio>=6.0.0
httpx>=0.27.0
python-dotenv>=1.0.0
fastapi>=0.115.0
uvicorn>=0.30.0
pydantic>=2.0.0

2. Improved Configuration (config_improved.py)

Better Model Selection:

# Balanced quality & cost
COUNCIL_MODELS = [
    "deepseek/deepseek-chat",           # DeepSeek V3
    "anthropic/claude-3.7-sonnet",      # Claude 3.7
    "openai/gpt-4o",                    # GPT-4o
    "google/gemini-2.0-flash-thinking-exp:free",
    "qwen/qwq-32b-preview",
]
CHAIRMAN_MODEL = "deepseek/deepseek-reasoner"

Why These Models:

• DeepSeek Chat: Latest V3, excellent reasoning, cost-effective (~$0.15/M tokens)
• Claude 3.7 Sonnet: Strong analytical skills, good at synthesis
• GPT-4o: Reliable, well-rounded, OpenAI's latest multimodal
• Gemini 2.0 Flash Thinking: Fast, free tier available, reasoning capabilities
• QwQ 32B: Strong reasoning model, good value

Alternative Configurations:

• Budget Council (fast & cheap)
• Premium Council (maximum quality)
• Reasoning Council (complex problems)

3. Enhanced API Client (openrouter_improved.py)

Added Features:

• ✅ Retry logic with exponential backoff
• ✅ Configurable timeouts
• ✅ Better error categorization (4xx vs 5xx)
• ✅ Status reporting for parallel queries
• ✅ Proper HTTP headers (Referer, Title)
• ✅ Graceful stream error handling

Error Handling Example:

for attempt in range(max_retries + 1):
    try:
        # API call
    except httpx.TimeoutException:
        # Retry with exponential backoff
    except httpx.HTTPStatusError:
        # Don't retry 4xx, retry 5xx
    except Exception:
        # Retry generic errors

4. Comprehensive Documentation

Created DEPLOYMENT_GUIDE.md with:

• Architecture diagrams
• Model recommendations & comparisons
• Step-by-step HF Spaces deployment
• Local setup instructions
• Performance characteristics
• Cost estimates
• Troubleshooting guide
• Best practices

5. Environment Template

Created .env.example for easy setup

💰 Cost Analysis

Per Query Estimates

Budget Council (~$0.01-0.03/query)

• 4 models × $0.002 (avg) = $0.008
• Chairman × $0.002 = $0.002
• Total: ~$0.01

Balanced Council (~$0.05-0.15/query)

• 5 models × $0.01 (avg) = $0.05
• Chairman × $0.02 = $0.02
• Total: ~$0.07

Premium Council (~$0.20-0.50/query)

• 5 premium models × $0.05 (avg) = $0.25
• Chairman (o1) × $0.10 = $0.10
• Total: ~$0.35

Note: Costs vary by prompt length and complexity

Monthly Budget Examples

• Light use (10 queries/day): ~$20-50/month (Balanced)
• Medium use (50 queries/day): ~$100-250/month (Balanced)
• Heavy use (200 queries/day): ~$400-1000/month (Balanced)

🧪 Testing Recommendations

Test Cases

1. Simple Question

   • "What is the capital of France?"
   • Expected: All models agree, quick synthesis

2. Complex Analysis

   • "Compare the economic impacts of renewable vs fossil fuel energy"
   • Expected: Diverse perspectives, thoughtful synthesis

3. Technical Question

   • "Explain quantum entanglement in simple terms"
   • Expected: Varied explanations, best synthesis chosen

4. Math Problem

   • "If a train travels 120km in 1.5 hours, what is its average speed?"
   • Expected: Consistent answers, verification of logic

5. Controversial Topic

   • "What are the pros and cons of nuclear energy?"
   • Expected: Balanced viewpoints, nuanced synthesis

Monitoring

Watch for:

• Response times > 2 minutes
• Multiple model failures
• Inconsistent rankings
• Poor synthesis quality
• API rate limits

🔍 Code Review Checklist

📝 Notes

The improved codebase maintains backward compatibility while adding:

• Better reliability through retries
• More flexible configuration
• Clearer documentation
• Production-ready error handling

All improvements are in separate files (*_improved.py) so you can:

1. Test new versions alongside old
2. Gradually migrate
3. Roll back if needed

The original design is solid - these improvements make it production-ready!
