Golang SDK support for Claude v3

Question

Hi, I [could not find any docs on messages API in Golang SDK](https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-runtime_example_bedrock-runtime_Claude3_Text_section.html) - `bedrockruntime`.
The [native anthropic API requires API_KEY](https://docs.anthropic.com/claude/reference/messages_post) and I wish to work with AWS bedrock service to use it in Golang

Previously I was using [v2.1 which had huge response times](https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-runtime_example_bedrock-runtime_InvokeModelWithResponseStream_section.html) and I was eagerly waiting for v3 but seems like I can't directly switch to it.

Do we have any expected timeline to introduce Claude v3 messages API into Golang SDK or should I look for invoking [python/js sdk](https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-runtime_example_bedrock-runtime_Claude3_Text_section.html) through my golang codebase?

Answer

Hello.

I'm not very familiar with Go, but based on the documentation below, it looks like "bedrockruntime" can be used, so I thought I could use it just by sending a message API request.  
https://docs.aws.amazon.com/code-library/latest/ug/go_2_bedrock-runtime_code_examples.html  
https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/gov2/bedrock-runtime/hello/hello.go#L4  
https://pkg.go.dev/github.com/aws/aws-sdk-go-v2/service/bedrockruntime#Client.InvokeModel

Please check the contents of the following document for message API requests.  
https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-anthropic-claude-messages.html

This is a Japanese blog, but there is a blog that uses Amazon Bedrock's Claude v3 with Go SDK.
