Models

==========================

|
|
.. note::
|
|
`Conceptual Guide <https://docs.langchain.com/docs/components/models>`_
|
|
|
|
|
|
This section of the documentation deals with different types of models that are used in LangChain.
|
|
On this page we will go over the model types at a high level,
|
|
but we have individual pages for each model type.
|
|
The pages contain more detailed "how-to" guides for working with that model,
|
|
as well as a list of different model providers.
|
|
|
|
**LLMs**
|
|
|
|
Large Language Models (LLMs) are the first type of models we cover.
|
|
These models take a text string as input, and return a text string as output.
|
|
|
|
|
|
**Chat Models**
|
|
|
|
Chat Models are the second type of models we cover.
|
|
These models are usually backed by a language model, but their APIs are more structured.
|
|
Specifically, these models take a list of Chat Messages as input, and return a Chat Message.
|
|
|
|
**Text Embedding Models**
|
|
|
|
The third type of models we cover are text embedding models.
|
|
These models take text as input and return a list of floats.
