Bedrock
=======

> [Amazon Bedrock](https://aws.amazon.com/bedrock/) is a fully managed service that makes Foundation Models (FMs) from leading AI startups and Amazon available via an API. You can choose from a wide range of FMs to find the model that is best suited for your use case.

Setup[​](#setup "Direct link to Setup")
---------------------------------------

You'll need to install a few official AWS packages as peer dependencies:

*   npm
*   Yarn
*   pnpm

    npm install @aws-crypto/sha256-js @aws-sdk/credential-provider-node @smithy/protocol-http @smithy/signature-v4 @smithy/eventstream-codec @smithy/util-utf8 @aws-sdk/types

    yarn add @aws-crypto/sha256-js @aws-sdk/credential-provider-node @smithy/protocol-http @smithy/signature-v4 @smithy/eventstream-codec @smithy/util-utf8 @aws-sdk/types

    pnpm add @aws-crypto/sha256-js @aws-sdk/credential-provider-node @smithy/protocol-http @smithy/signature-v4 @smithy/eventstream-codec @smithy/util-utf8 @aws-sdk/types

You can also use Bedrock in web environments such as Edge functions or Cloudflare Workers by omitting the `@aws-sdk/credential-provider-node` dependency and using the `web` entrypoint:

*   npm
*   Yarn
*   pnpm

    npm install @aws-crypto/sha256-js @smithy/protocol-http @smithy/signature-v4 @smithy/eventstream-codec @smithy/util-utf8 @aws-sdk/types

    yarn add @aws-crypto/sha256-js @smithy/protocol-http @smithy/signature-v4 @smithy/eventstream-codec @smithy/util-utf8 @aws-sdk/types

    pnpm add @aws-crypto/sha256-js @smithy/protocol-http @smithy/signature-v4 @smithy/eventstream-codec @smithy/util-utf8 @aws-sdk/types

Usage[​](#usage "Direct link to Usage")
---------------------------------------

tip

See [this section for general instructions on installing integration packages](/v0.1/docs/get_started/installation/#installing-integration-packages).

*   npm
*   Yarn
*   pnpm

    npm install @langchain/community

    yarn add @langchain/community

    pnpm add @langchain/community

Note that some models require specific prompting techniques. For example, Anthropic's Claude-v2 model will throw an error if the prompt does not start with `Human:` .

    import { Bedrock } from "@langchain/community/llms/bedrock";// Or, from web environments:// import { Bedrock } from "@langchain/community/llms/bedrock/web";// If no credentials are provided, the default credentials from// @aws-sdk/credential-provider-node will be used.const model = new Bedrock({  model: "ai21.j2-grande-instruct", // You can also do e.g. "anthropic.claude-v2"  region: "us-east-1",  // endpointUrl: "custom.amazonaws.com",  // credentials: {  //   accessKeyId: process.env.BEDROCK_AWS_ACCESS_KEY_ID!,  //   secretAccessKey: process.env.BEDROCK_AWS_SECRET_ACCESS_KEY!,  // },  // modelKwargs: {},});const res = await model.invoke("Tell me a joke");console.log(res);/*  Why was the math book unhappy?  Because it had too many problems!*/
