Amazon
Bundles contain custom components that support specific third-party integrations with Langflow.
This page describes the components that are available in the Amazon bundle.
Amazon Bedrock
This component generates text using Amazon Bedrock LLMs.
It can output either a Model Response (Message
) or a Language Model (LanguageModel
).
Specifically, the Language Model output is an instance of ChatBedrock
configured according to the component's parameters.
Use the Language Model output when you want to use an Amazon Bedrock model as the LLM for another LLM-driven component, such as an Agent or Smart Function component.
For more information, see Language Model components.

Some parameters are hidden by default in the visual editor. You can modify all parameters through the Controls in the component's header menu.
