# LLM integrations

> Integrate with LLMs using LangChain JavaScript.

<Warning>
  **You are currently on a page documenting the use of text completion models. Many of the latest and most popular models are [chat completion models](/oss/javascript/langchain/models).**

  Unless you are specifically using more advanced prompting techniques, you are probably looking for [this page instead](/oss/javascript/integrations/chat/).
</Warning>

[LLMs](/oss/javascript/langchain/models) are language models that takes a string as input and return a string as output.
