# Chat models

[Chat models](/docs/concepts/#chat-models) are language models that use a sequence of [messages](/docs/concepts/#messages) as inputs and return messages as outputs (as opposed to using plain text). These are generally newer models.

:::info

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