# LLMs

:::caution
You are currently on a page documenting the use of [text completion models](/docs/concepts/#llms). Many of the latest and most popular models are [chat completion models](/docs/concepts/#chat-models).

Unless you are specifically using more advanced prompting techniques, you are probably looking for [this page instead](/docs/integrations/chat/).
:::

[LLMs](docs/concepts/#llms) are language models that take a string as input and return a string as output.

:::info

If you'd like to write your own LLM, see [this how-to](/docs/how_to/custom_llm/).
If you'd like to contribute an integration, see [Contributing integrations](/docs/contributing/integrations/).
