`Conceptual Guide <https://docs.langchain.com/docs/components/prompts>`_
|
|
|
|
|
|
The new way of programming models is through prompts.
|
|
A "prompt" refers to the input to the model.
|
|
This input is rarely hard coded, but rather is often constructed from multiple components.
|
|
A PromptTemplate is responsible for the construction of this input.
|
|
LangChain provides several classes and functions to make constructing and working with prompts easy.
|
|
|
|
This section of documentation is split into four sections:
|
|
|
|
**LLM Prompt Templates**
|
|
|
|
How to use PromptTemplates to prompt Language Models.
|
|
|
|
**Chat Prompt Templates**
|
|
|
|
How to use PromptTemplates to prompt Chat Models.
|
|
|
|
**Example Selectors**
|
|
|
|
Often times it is useful to include examples in prompts.
|
|
These examples can be hardcoded, but it is often more powerful if they are dynamically selected.
|
|
This section goes over example selection.
|
|
|
|
|
|
**Output Parsers**
|
|
|
|
Language models (and Chat Models) output text.
|
|
But many times you may want to get more structured information than just text back.
|
|
This is where output parsers come in.
|
|
Output Parsers are responsible for (1) instructing the model how output should be formatted,
|
|
(2) parsing output into the desired formatting (including retrying if necessary).
