Prompt Flow revolutionizes the development of AI applications. With visual tools, you can create complex LLM workflows without deep coding.
What is Prompt Flow?
Prompt Flow is a visual editor for:
- LLM Chaining – Orchestrating multiple model calls
- Data Integration – Incorporating external sources
- Logic Flows – Conditions and loops
- Testing – Automated quality assurance
Core Concepts
Nodes
Building blocks of a flow:
- LLM Nodes – Model calls
- Python Nodes – Custom code
- Tool Nodes – External functions
- Prompt Nodes – Template processing
Connections
Connections to:
- Azure OpenAI
- Custom Endpoints
- Data sources
- APIs
Variants
Testing different versions:
- A/B testing of prompts
- Model comparisons
- Performance optimization
Practical Example: RAG System
Step 1: Index Search
Input: User question → Vector Search in Azure AI Search → Output: Relevant documents
Step 2: Context Building
Input: Documents + Question → Python: Assemble context → Output: Enhanced prompt
Step 3: LLM Call
Input: Context + System prompt → GPT-4 Turbo → Output: Answer
Step 4: Post-Processing
Input: LLM answer → Formatting, citations → Output: Final answer
