AI Engineering
Strengths
+ Clear, accessible explanations of complex AI/ML concepts
+ Practical and implementation-focused rather than theoretical
+ Well-researched with extensive references to current literature
+ Excellent for software engineers transitioning into AI development
Caveats
− Inconsistent depth: some topics feel surface-level for experienced practitioners
− Limited practical code examples
− Breadth-first approach means some topics lack deep coverage
Prompt Engineering for LLMs
Strengths
+ Focuses on understanding why techniques work, not just memorizing patterns
+ Written by practitioners who build one of the world's largest LLM products
+ Good visual explanations and exercises throughout
+ Research-backed approach with references for deeper exploration
Caveats
− Heavy GPT-3 focus makes some content feel dated
− Longer than it needs to be, some sections are unnecessarily verbose
− Some later chapters feel too abstract for practical application
The verdict
AI Engineering is the stronger pick overall, but Prompt Engineering for LLMs may suit you better if you're a developers building LLM-powered applications.

Frequently asked
Which is better, AI Engineering or Prompt Engineering for LLMs?
AI Engineering is the stronger pick overall, but Prompt Engineering for LLMs may suit you better if you're a developers building LLM-powered applications.
Is AI Engineering good for beginners?
You need some software engineering experience. It's not a learn-to-code book. But you don't need a PhD in ML either. If you can write Python and understand APIs, you'll follow along.
Is this just a collection of prompt templates?
No. It focuses on understanding why prompts work at the architectural level. You'll learn principles that apply to any model, not templates that stop working when models update.
