# Embeddings AWS Bedrock

Use the Embeddings AWS Bedrock node to generate embeddings[^1] for a given text.

On this page, you'll find the node parameters for the Embeddings AWS Bedrock node, and links to more resources.

**Credentials**

You can find authentication information for this node [here](/integrations/builtin/credentials/aws.md).

{% hint style="info" %}
**Parameter resolution in sub-nodes**

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five `name` values, the expression `{{ $json.name }}` resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five `name` values, the expression `{{ $json.name }}` always resolves to the first name.

## Node parameters <a href="#node-parameters" id="node-parameters"></a>

* **Authentication**: Select the authentication method:
  * **AWS (IAM)**: Use an IAM access key. Select an **AWS** credential.
  * **AWS (Assume Role)**: Temporarily assume an IAM role. Select an **AWS (Assume Role)** credential.
* **Model**: Select the model to use to generate the embedding. If the dropdown is empty, your IAM role may not have the `bedrock:ListFoundationModels` permission. Switch the field to **Expression** mode and enter the model ID directly.

Learn more about available models in the [Amazon Bedrock documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/what-is-bedrock.html).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.n8n.io/integrations/builtin/cluster-nodes/sub-nodes/n8n-nodes-langchain.embeddingsawsbedrock.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
