Amazon Bedrock Runtime code examples for the SDK for Go V2

Overview

Shows how to use the AWS SDK for Go V2 to work with Amazon Bedrock Runtime.

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 gov2 folder.

⚠ 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.

Get started

• Hello Amazon Bedrock (InvokeModel)

Single actions

Code excerpts that show you how to call individual service functions.

• Image generation with Amazon Titan Image Generator G1 (InvokeModel)
• Text generation with AI21 Labs Jurassic-2 (InvokeModel)
• Text generation with Anthropic Claude 2 (InvokeModel)
• Text generation with Anthropic Claude 2 with a response stream (InvokeModelWithResponseStream)
• Text generation with Meta Llama 2 Chat (InvokeModel)

Scenarios

Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

• Invoke multiple foundation models on Amazon Bedrock

Run the examples

Instructions

Region configuration

By default, examples are set to us-east-1. To specify a different region, use the -region flag as shown in this example:

go run ./hello -region=eu-central-1

Be aware that not all regions may support Bedrock and its models yet. Verify service availability for your region here. For available models per region, refer to the Bedrock dashboard in the AWS Management Console.

This example shows you how to get started using Amazon Bedrock.

go run ./hello

Run a scenario

All scenarios can be run with the cmd runner. To get a list of scenarios and to get help for running a scenario, use the following command:

go run ./cmd -h

Invoke multiple foundation models on Amazon Bedrock

This example shows you how to invoke multiple foundation models on Amazon Bedrock.

• Generate text with Anthropic Claude.
• Generate text with AI21 Labs Jurassic-2.
• Generate text with Meta Llama 2 Chat.
• Asynchronously process the response stream from Anthropic Claude.
• Generate an image with the Amazon Titan Image Generator.
