 A prompt template is a _pre-defined recipe for a prompt_ that can be stored and reused as needed, to drive more consistent user experiences at scale. In its simplest form, it is simply a collection of prompt examples like [this one from OpenAI](https://platform.openai.com/examples?WT.mc_id=academic-105485-koreyst) that provides both the interactive prompt components (user and system messages) and the API-driven request format - to support reuse.
 
-In it's more complex form like [this example from LangChain](https://python.langchain.com/docs/modules/model_io/prompts/prompt_templates/?WT.mc_id=academic-105485-koreyst) it contains _placeholders_ that can be replaced with data from a variety of sources (user input, system context, external data sources etc.) to generate a prompt dynamically. This allows us to create a library of reusable prompts that can be used to drive consistent user experiences **programmatically** at scale.

 Finally, the real value of templates lies in the ability to create and publish _prompt libraries_ for vertical application domains - where the prompt template is now _optimized_ to reflect application-specific context or examples that make the responses more relevant and accurate for the targeted user audience. The [Prompts For Edu](https://github.com/microsoft/prompts-for-edu?WT.mc_id=academic-105485-koreyst) repository is a great example of this approach, curating a library of prompts for the education domain with emphasis on key objectives like lesson planning, curriculum design, student tutoring etc.
