OpenRouter

Bundles 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.

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) or a Language Model (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.
