Amazon Bedrock Runtime code examples for the SDK for Java 2.x

Overview

Shows how to use the AWS SDK for Java 2.x to work with Amazon Bedrock Runtime.

<!--custom.overview.start--> <!--custom.overview.end-->

Amazon Bedrock Runtime is a fully managed service that makes it easy to use foundation models from third-party providers and Amazon.

⚠ Important

• Running this code might result in charges to your AWS account. For more details, see AWS Pricing and Free Tier.
• Running the tests might result in charges to your AWS account.
• We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
• This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Code examples

Prerequisites

For prerequisites, see the README in the javav2 folder.

<!--custom.prerequisites.start-->

⚠ You must request access to a model before you can use it. If you try to use the model (with the API or console) before you have requested access to it, you will receive an error message. For more information, see Model access.

Generate videos from text prompts using Amazon Bedrock

This example shows you how to a Spring Boot app that generates videos from text prompts using Amazon Bedrock and the Nova-Reel model.

Tool use with the Converse API

This example shows you how to build a typical interaction between an application, a generative AI model, and connected tools or APIs to mediate interactions between the AI and the outside world. It uses the example of connecting an external weather API to the AI model so it can provide real-time weather information based on user input.
