[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 **OpenRouter** bundle.
|
|
|
|
For more information about OpenRouter features and functionality used by OpenRouter components, see the [OpenRouter documentation](https://openrouter.ai/docs).

## OpenRouter text generation
|
|
|
|
This component generates text using OpenRouter's unified API for multiple AI models from different providers.
|
|
|
|
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 an OpenRouter 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).
|
|
|
|
### OpenRouter text generation parameters
|
|
|
|
Many **OpenRouter** 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).
