Language models take text as input - that text is commonly referred to as a prompt. Typically this is not simply a hardcoded string but rather a combination of a template, some examples, and user input. LangChain provides several classes and functions to make constructing and working with prompts easy.
A prompt template refers to a reproducible way to generate a prompt. It contains a text string ("the template"), that can take in a set of parameters from the end user and generates a prompt.
A prompt template can contain:
- instructions to the language model,
- a set of few shot examples to help the language model generate a better response,
- a question to the language model.
