Overview of this book

Foundation models have forever changed machine learning. From BERT to ChatGPT, CLIP to Stable Diffusion, when billions of parameters are combined with large datasets and hundreds to thousands of GPUs, the result is nothing short of record-breaking. The recommendations, advice, and code samples in this book will help you pretrain and fine-tune your own foundation models from scratch on AWS and Amazon SageMaker, while applying them to hundreds of use cases across your organization. With advice from seasoned AWS and machine learning expert Emily Webber, this book helps you learn everything you need to go from project ideation to dataset preparation, training, evaluation, and deployment for large language, vision, and multimodal models. With step-by-step explanations of essential concepts and practical examples, you’ll go from mastering the concept of pretraining to preparing your dataset and model, configuring your environment, training, fine-tuning, evaluating, deploying, and optimizing your foundation models. You will learn how to apply the scaling laws to distributing your model and dataset over multiple GPUs, remove bias, achieve high throughput, and build deployment pipelines. By the end of this book, you’ll be well equipped to embark on your own project to pretrain and fine-tune the foundation models of the future.

Model monitoring and human-in-the-loop

In Chapter 11, we explored topics around bias detection, mitigation, and monitoring for large vision and language models. This was mostly in the context of evaluating your model. Now that we’ve made it to the section on deploying your models, with an extra focus on operations, let’s take a closer look at model monitoring.

Once you have a model deployed into any application, it’s extremely useful to be able to view the performance of that model over time. This is the case for any of the use cases we discussed earlier – chat, general search, forecasting, image generation, recommendations, classification, question answering, and so on. All of these applications benefit from being able to see how your model is trending over time and provide relevant alerts.

Imagine, for example, that you have a price forecasting model that suggests a price for a given product based on economic conditions. You train your model on certain...
