Improving written text with Amazon SageMaker “Amazon SageMaker makes it possible for us to develop our TensorFlow models in a distributed training environment. (…) We can run inference on SageMaker itself, or if we need just the model, we download it from S3 and run inference of our mobile device implementations for iOS and Android customers.”
