## 聊天模型

### Bedrock

查看 [使用示例](/oss/javascript/integrations/chat/bedrock)。

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { BedrockChat } from "@langchain/community/chat_models/bedrock";
```

## 大语言模型

### Bedrock

查看 [使用示例](/oss/javascript/integrations/llms/bedrock)。

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { Bedrock } from "@langchain/community/llms/bedrock";
```

### SageMaker 端点

> [Amazon SageMaker](https://aws.amazon.com/sagemaker/) 是一个系统，可以使用完全托管的基础设施、工具和工作流来构建、训练和部署机器学习（ML）模型。

我们使用 `SageMaker` 来托管我们的模型，并将其作为 `SageMaker Endpoint` 暴露出来。

查看 [使用示例](/oss/javascript/integrations/llms/aws_sagemaker)。

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import {
  SagemakerEndpoint,
  SageMakerLLMContentHandler,
} from "@langchain/community/llms/sagemaker_endpoint";
```

## 文本嵌入模型

### Bedrock

查看 [使用示例](/oss/javascript/integrations/embeddings/bedrock)。

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { BedrockEmbeddings } from "@langchain/aws";
```

## 文档加载器

### AWS S3 目录和文件

> [Amazon Simple Storage Service (Amazon S3)](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-folders.html) 是一个对象存储服务。
> [AWS S3 目录](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-folders.html) >[AWS S3 存储桶](https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingBucket.html)

查看 [S3FileLoader 使用示例](/oss/javascript/integrations/document_loaders/web_loaders/s3)。

```bash npm theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
npm install @aws-sdk/client-s3
```

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { S3Loader } from "@langchain/community/document_loaders/web/s3";
```
