            In order to access Anthropic models on Bedrock you must require the `aws-sdk-bedrockruntime` gem.
            You can install it by adding the following to your Gemfile:

                gem "aws-sdk-bedrockruntime"

            and then running `bundle install`.

            Alternatively, if you are not using Bundler, simply run:

                gem install aws-sdk-bedrockruntime
