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 a Language Model or Smart Function component.
For more information, see Language Model components.
Amazon Bedrock parameters
Many Amazon Bedrock component input parameters are hidden by default in the visual editor. You can toggle parameters through the Controls in the component's header menu.

| model_id | String | Input parameter. The ID of the Amazon Bedrock model to use. Options include various models. |
| aws_access_key | SecretString | Input parameter. AWS Access Key for authentication. |

For more information about using embedding model components in flows, see Embedding Model components.
