Hands-On Large Language Models
Strengths
+ 275+ custom diagrams make abstract concepts visual and intuitive
+ Accessible to beginners without prior PyTorch/TensorFlow knowledge
+ Practical code examples covering real use cases like semantic search and RAG
+ Well-structured progression from foundations to advanced techniques
Caveats
− Limited depth on transformer internals despite the author's blog reputation
− Image generation sections lack clarity
− May be too introductory for experienced ML practitioners
LLM Engineer's Handbook
Strengths
+ End-to-end production focus covering the full LLM pipeline
+ Bridges the gap between research papers and real-world implementation
+ Authors bring real experience from building GenAI systems at scale
+ Amazon Bestseller with 10,000+ copies sold globally
Caveats
− Writing tends to over-explain trivial details while skipping architectural decisions
− Code examples have inconsistent patterns and small bugs
− Breadth-first approach means limited depth on any single topic
The verdict
Read Hands-On Large Language Models first to build foundations, then move to LLM Engineer's Handbook for advanced concepts.

Frequently asked
Which is better, Hands-On Large Language Models or LLM Engineer's Handbook?
Read Hands-On Large Language Models first to build foundations, then move to LLM Engineer's Handbook for advanced concepts.
Is Hands-On Large Language Models good for beginners?
Yes, it's one of the most beginner-friendly LLM books available. No PyTorch or TensorFlow experience needed. The 275+ diagrams carry a lot of the explanation load.
Is the LLM Engineer's Handbook good for beginners?
You need familiarity with Python, basic ML concepts, and ideally some cloud/AWS experience. It's not a first book on AI, but it's approachable for mid-level engineers.
