Best Practices¶

Model Selection¶

• Use GPT-3.5-Turbo for cost-effective scenarios
• Use GPT-4 for complex reasoning tasks
• Choose appropriate token limits for use case
• Consider latency requirements
• Balance cost vs capability needs
• Test multiple models for your scenario

Prompt Engineering¶

• Provide clear instructions and context
• Use system messages to set behavior
• Include examples (few-shot learning)
• Be specific about output format
• Iterate and refine prompts based on results
• Use delimiters to separate sections
• Ask model to think step-by-step for complex tasks

Response Configuration¶

• Set temperature for creativity vs consistency trade-off
• Use top_p for nucleus sampling
• Set max_tokens to control response length
• Use frequency_penalty to reduce repetition
• Use presence_penalty to encourage topic diversity
• Implement stop sequences when appropriate

Data Grounding (RAG Pattern)¶

• Index relevant data in Cognitive Search
• Retrieve relevant context for prompts
• Include source citations in responses
• Update knowledge base regularly
• Balance context length with relevance
• Implement semantic search for better retrieval

Safety and Compliance¶

• Enable content filtering for harmful content
• Implement input validation
• Review generated content appropriately
• Handle sensitive data with care
• Monitor for bias and problematic outputs
• Implement user feedback mechanisms
