LLMs are here and seem to be the go-to for everything; however, there is still space for the traditional methods. Ironically, this is exactly what I said in my speech at the AI World Congress 2025, and Deep Learning with Python, Third Edition illustrates that point perfectly.
This substantial volume - around 600 pages across 20 chapters - delivers a comprehensive and structured journey into modern deep learning. As a 3rd edition, it feels mature and refined. The opening chapter provides clear, high-level definitions of fundamental concepts, offering a gentle introduction to the principles behind machine learning, deep learning’s rise in popularity, and where the field is heading.
From there, the book moves rapidly into practical territory. It covers all the major frameworks - Keras, TensorFlow, PyTorch, and JAX - supported by plenty of code examples that allow concepts to be applied immediately. It does not shy away from breadth either: image classification, time series modelling, object detection, and, as is now essential, transformers, all receive well-structured treatment. Each chapter ends with a concise, very useful summary that reinforces understanding and highlights key takeaways.
A standout section for this reader was “Best Practices for the Real World”, which provides grounded guidance on hyperparameter tuning, ensembles, and quantisation. These topics are often overlooked in introductory texts but are essential for real deployments.
Some reasonable Python knowledge is needed, but the book remains approachable. It suits beginners aiming to break into deep learning as well as experienced practitioners looking to broaden their toolkit.
Highly recommended.

As a working programmer who has been trying to deepen my understanding of modern machine learning, I found this book to be one of the clearest and most practical introductions to deep learning. François Chollet has a talent for explaining complex ideas in a way that feels intuitive without oversimplifying them. The third edition is especially valuable because it reflects the current state of the field, including Keras 3 and its integration with TensorFlow, PyTorch and JAX.
The book follows a very hands-on approach. Nearly every concept is paired with code that you can run and experiment with, which makes the learning experience far more concrete. The examples feel modern and relevant, covering everything from image classification and sequence modeling to generative techniques like text and image generation. As someone who learns best by building, this style worked extremely well for me.
A small note for beginners: the book assumes you are comfortable with Python. You do not need a math-heavy background, but you should be ready to write and tweak code. Some of the later chapters move faster and may require revisiting if you’re new to the field, but the progression is well-structured and worth the effort.
Overall, this is one of the most practical and accessible deep learning resources available. It combines clarity, modern techniques and immediately usable code examples. If you’re a developer looking to get into deep learning or refresh your understanding with up-to-date practices, this book is an excellent choice. I would highly recommend it.

I've read this book on my journey to learn AI and Deep Learning and I must say, it's the most complete and updated about Deep Learning with Python.
It covers everything from the basics—chapter 1 gives a very accessible introduction to AI and deep learning, from modern topics like transformers, GPT-like language models, and diffusion models for image generation.
Every chapter includes clean, and, very important, examples that run in Keras, TensorFlow, PyTorch, and JAX.
You build classifiers, CNNs, RNNs, LSTMs, etc... You named it. It describes modern techniques that most books don't have, like a step-by-step implementation of language models an transformers.
It's a great balance between theory and practice. Chollet explains in a natural and intuitive way.
The feature-engineering explanation using the clock-hand metaphor is brilliant. :)
For what I think is not so good:
- For someone looking to learn something in a weekend, this is not your book. It's a bit overwhelming - a fantastic learning guide, but a bit bulky for a weekend reading.
You need to know Python and have the heart to learn some math ! :)
- You need to have a decent GPU for the examples and some advance models. With only the CPU you will suffer a bit.
Overall, and in my opinion, it's one of the best (if not the best) book to learn deep learning with Python. It's clear, modern and did I mention it was written by the creator of Keras ?
It's essential for anyone working with AI in 2025 .

Deep Learning moves fast, and this Third Edition finally catches up to the Generative AI boom. The addition of Matthew Watson as a co-author is felt in the NLP sections, which are much more robust now.
The key value prop here is Keras 3. Seeing how to build a model once and deploy it on JAX or PyTorch is invaluable for production workflows. The book cuts through the hype of LLMs and Diffusion models to show you exactly how they are architected.
It’s a dense read but incredibly high ROI for your time. A must-have reference for 2025.

This book is an excellent, hands-on introduction to modern deep learning that stays both practical and accessible. Chollet and Watson explain complex ideas clearly, with clean Keras examples and up-to-date coverage of topics like transformers and large language models, making it a great choice for both learners and working engineers.

I really enjoyed reading this book. It's rare for a technical text to be both informative and genuinely engaging, and that's what sets it apart from many modern ML books that are often filled with cliches and lack real depth. This book provides a solid foundation in deep learning and is an excellent guide for keeping up with the fast moving world of ML

It’s an excellent book. It starts with the basics and builds up to the state-of-the-art of Deep Learning. I especially enjoyed the chapter "Future of AI".
If you prefer learning by doing, you’ll appreciate that every chapter comes with code.

I liked this book more than I expected. The writing is clear, and the examples are straightforward to follow. I think it works well for beginners, but even with some experience in ML I still picked up useful insights.
