[Bundles](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.
|
|
|
|
This page describes the components that are available in the **Perplexity** bundle.
|
|
|
|
For more information about Perplexity features and functionality used by Perplexity components, see the [Perplexity documentation](https://perplexity.ai/).

## Perplexity text generation
|
|
|
|
This component generates text using Perplexity's language models.
|
|
|
|
It can output either a **Model Response** ([`Message`](/data-types#message)) or a **Language Model** ([`LanguageModel`](/data-types#languagemodel)).
|
|
|
|
Use the **Language Model** output when you want to use a Perplexity model as the LLM for another LLM-driven component, such as a **Language Model** or **Smart Function** component.
|
|
|
|
For more information, see [**Language Model** components](/components-models).
|
|
|
|
### Perplexity text generation parameters
|
|
|
|
Many **Perplexity** component input parameters are hidden by default in the visual editor.
|
|
You can toggle parameters through the <Icon name="SlidersHorizontal" aria-hidden="true"/> **Controls** in the [component's header menu](/concepts-components#component-menus).
