 ## How it works
 
 * Start the Express Workflow using the `start-sync-execution` api command with a "prompt" string in English for generating content as per the input payload.
-* The Express Workflow invokes Amazon Bedrock Anthropic Claude v2.1 Model with the prompt.
+* The Express Workflow invokes Amazon Bedrock Anthropic Claude Sonnet 4.5 with the prompt.
 * Amazon Bedrock returns the generated content as the given promptsentiment of the input text. 
 * If the integration succeeds, the generated content is returned in the Step Function execution results within an `output` object.
 * If the integration fails, the Step Functions workflow will retry up to 5 times before exiting with a `status:FAILED` response.
