Build Dynamic AI Prompts with LangChain Templates

Problem

Hard-coded prompts limit flexibility and make it difficult to adapt AI applications to different contexts or user inputs.

Creating separate functions for each prompt variation leads to duplicate code with no reusability.

Solution

LangChain’s PromptTemplate enables dynamic, reusable prompts with variable substitution.

Create one template that adapts to multiple contexts:

• Variable substitution with {topic}, {audience}, {examples}
• Single template for unlimited prompt variations
• Clean, maintainable code structure
• Compatible with all major LLM providers

Transform repetitive hard-coded prompts into flexible, reusable templates that scale with your AI application needs.
