Understand the architecture that underpins today’s most powerful AI models. Transformers are the superpower behind large language models (LLMs) like ChatGPT, Gemini, and Claude. Transformers in Action gives you the insights, practical techniques, and extensive code samples you need to adapt pretrained transformer models to new and exciting tasks. Inside Transformers in Action you’ll learn: • How transformers and LLMs work • Modeling families and architecture variants • Efficient and specialized large language models • Adapt HuggingFace models to new tasks • Automate hyperparameter search with Ray Tune and Optuna • Optimize LLM model performance • Advanced prompting and zero/few-shot learning • Text generation with reinforcement learning • Responsible LLMs Transformers in Action takes you from the origins of transformers all the way to fine-tuning an LLM for your own projects. Author Nicole Koenigstein demonstrates the vital mathematical and theoretical background of the transformer architecture practically through executable Jupyter notebooks. You’ll discover advice on prompt engineering, as well as proven-and-tested methods for optimizing and tuning large language models. Plus, you’ll find unique coverage of AI ethics, specialized smaller models, and the decoder encoder architecture. Foreword by Luis Serrano. About the technology Transformers are the beating heart of large language models (LLMs) and other generative AI tools. These powerful neural networks use a mechanism called self-attention, which enables them to dynamically evaluate the relevance of each input element in context. Transformer-based models can understand and generate natural language, translate between languages, summarize text, and even write code—all with impressive fluency and coherence. About the book Transformers in Action introduces you to transformers and large language models with careful attention to their design and mathematical underpinnings. You’ll learn why architecture matters for speed, scale, and retrieval as you explore applications including RAG and multi-modal models. Along the way, you’ll discover how to optimize training and performance using advanced sampling and decoding techniques, use reinforcement learning to align models with human preferences, and more. The hands-on Jupyter notebooks and real-world examples ensure you’ll see transformers in action as you go. What's inside • Optimizing LLM model performance • Adapting HuggingFace models to new tasks • How transformers and LLMs work under the hood • Mitigating bias and responsible ethics in LLMs About the reader For data scientists and machine learning engineers.
