<Icon name="Blocks" aria-hidden="true" /> [**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 an **Agent** or **Smart Transform** component.
For more information, see [Language model components](/components-models).
