Everybody talks about shipping AI products, but nobody shows you how.

These 5 books are all you need (and yes... I've read them all):

𝟭/ 𝗗𝗲𝘀𝗶𝗴𝗻𝗶𝗻𝗴 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗯𝘆 Chip Huyen 
🔗: https://lnkd.in/dwmcghyA

One of the best books I've read on designing ML systems.

It's beginner-friendly.

And it provides a strong intuition into what an end-to-end ML system looks like.

𝟮/ 𝗣𝗿𝗼𝗺𝗽𝘁 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗳𝗼𝗿 𝗟𝗟𝗠𝘀 𝗯𝘆 John Berryman 𝗮𝗻𝗱 Albert Ziegler 
🔗: https://lnkd.in/dGXBYAFU

If you're obsessed with seeing the big picture and thinking in systems (like me), you'll love this book.

It will show you how to engineer your prompts effectively.

You will also learn how to manipulate your prompt, make it flexible, scalable, and squeeze the most out of your models.

P.S. As John said, this book should be called 𝗖𝗼𝗻𝘁𝗲𝘅𝘁 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗳𝗼𝗿 𝗟𝗟𝗠𝘀.

𝟯/ 𝗔𝗜 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗯𝘆 Chip Huyen 
🔗: https://lnkd.in/dPKStJW3

This book has one of the best (and clearest) explanations of:

• AI vs. ML Engineering
• RAG (from classic text search to more complex, semantic-based systems)
• Building agentic systems
• LLMOps (Especially observability and user feedback)
  
𝟰/ 𝗕𝘂𝗶𝗹𝗱𝗶𝗻𝗴 𝗟𝗟𝗠𝘀 𝗳𝗼𝗿 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗯𝘆 Louis-François Bouchard 𝗮𝗻𝗱 Louie Peters 
🔗: https://lnkd.in/d9v6HyZr (𝟭𝟱% 𝗼𝗳𝗳 𝘂𝘀𝗶𝗻𝗴 𝗮𝗳𝗳𝗶𝗹𝗶𝗮𝘁𝗲 𝗰𝗼𝗱𝗲 𝗣𝗮𝘂𝗹_𝟭𝟱)

This book will walk you through how to implement all the core algorithms required to build LLM applications.

You'll use LangChain and LlamaIndex to implement all kinds of RAG techniques (starting from the vanilla architecture).

It's great for people who are mid-to-entry-level engineers.

𝟱/ 𝗟𝗟𝗠𝘀 𝗶𝗻 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗯𝘆 Chris Brousseau 𝗮𝗻𝗱 Matthew Sharp 
🔗: https://lnkd.in/d_xqpfUz

This book focuses entirely on shipping AI.

Specifically, it does a great job of explaining:

• How to optimize LLMs using different tools
• The data engineering involved in building an LLM app
• Training and serving LLMs at scale
• How to think about infrastructure when serving LLMs
• etc.
  
𝗕𝗢𝗡𝗨𝗦: 𝗟𝗟𝗠 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿'𝘀 𝗛𝗮𝗻𝗱𝗯𝗼𝗼𝗸 𝗯𝘆 𝗺𝗲 𝗮𝗻𝗱 Maxime Labonne 
Link: https://lnkd.in/dRmBZXdR

I couldn't list a bunch of books without mentioning my baby.

This book merges my obsession with thinking about end-to-end systems with Maxime Labonne 's love for fine-tuning.

We walk you through all the steps to build an LLM & RAG application.

Oh… and we’re working on a 2nd edition due to popular demand.

P.S. How many of these books have you read?

Senior AI Engineer • Founder @ Decoding AI ~ Building an army of AI agents and teaching you about the process.

90% of AI engineers build LLM apps the same way.

They spin up a RAG system, tweak a few prompts, and then ask:

"Does it work?"

Or worse... "Should I switch to the new model that just dropped?"

But these are the wrong questions to be asking.

Why? Because you have no way to know.

It's impossible to answer these questions without an evaluation framework.

This is why Hugo Bowne-Anderson suggests we use Evaluation-Driven Development (EDD).

The concept isn't new (especially for those with a background in ML).

The idea is to shift the development mindset from launch first, evaluate later to evaluate first, launch better.

Here's how it works:

1. 𝗨𝘀𝗲 𝘀𝘆𝗻𝘁𝗵𝗲𝘁𝗶𝗰 𝗱𝗮𝘁𝗮 to uncover failure modes before launch.
2. 𝗟𝗮𝗯𝗲𝗹 𝗯𝘆 𝗵𝗮𝗻𝗱 to build intuition about what “good” looks like.
3. 𝗕𝘂𝗶𝗹𝗱 𝗮 𝘀𝗶𝗺𝗽𝗹𝗲 𝗲𝘃𝗮𝗹𝘂𝗮𝘁𝗶𝗼𝗻 𝗵𝗮𝗿𝗻𝗲𝘀𝘀 - even a spreadsheet is enough.
4. 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗲 it to track changes over time.
   
This loop will help you compare models, debug failures, and build confidence that your system works before it hits production.

You wouldn’t build a search engine or recommender system without robust evaluation.... 
So why build an LLM app without one?

Hugo Bowne-Anderson explains EDD beautifully in a guest post he wrote for Decoding AI Magazine.

It’s one of the most practical, no-fluff guides I’ve read on building reliable LLM systems.

Legislative Budget Board

I was the principal author of the State's Adult Correctional Population Projections for 2016 and 2017. The latter set of projections informed funding decisions made by the House and Senate Appropriations Committee of the Texas Legislature. Producing the projections required database management, simulation software, statistical analysis, and qualitative field work. The field work involved visiting various state penitentiaries such as the famous Walls Unit in Huntsville. I also spoke with numerous criminal justice stakeholders across the state, including the executive director of the Texas Department of Criminal Justice (TDCJ), his deputy, state judges, and wardens. 

The Legislative Budget Board (LBB) is a permanent joint committee of the Texas Legislature that develops budget and policy recommendations for legislative appropriations, completes fiscal analyses for proposed legislation, and conducts evaluations and reviews to improve the efficiency and performance of state and local operations.

During the interim, the LBB provides assistance to standing and special committees, as requested. In addition, several reports serve to keep the Legislature informed about significant budget and performance developments among state agencies. A major publication, Fiscal Size-up, summarizes important fiscal actions of the prior legislative session, describes the purpose and services of state agencies, and provides comparative information on Texas state government.

During the legislative session, the LBB supports the legislative appropriations process by providing staff resources for the House Appropriations Committee, the Senate Finance Committee, and the Conference Committee on Appropriations. To a great extent, staff support takes the form of tracking committee decisions, answering inquiries from committee members, and performing analyses. In addition to committee support services, LBB staff members prepare fiscal notes and impact statements about proposed legislation.
