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 an Agent or Smart Transform component.

For more information, see Language model components.
