AWS/Blog/25/05/Introducing Claude 4 in Amazon Bedrock
- To see Opus 4 or Sonnet 4 in action, enable the new model in your AWS account. Then, you can start coding using the Bedrock Converse API with model ID
anthropic.claude-opus-4-20250514-v1:0 for Opus 4 and anthropic.claude-sonnet-4-20250514-v1:0 for Sonnet 4. We recommend using the Converse API, because it provides a consistent API that works with all Amazon Bedrock models that support messages. This means you can write code one time and use it with different models.
