    Great for getting started w/LLM apps
  

*by H***T on Reviewed in the United States on January 5, 2024*

I have not used LangChain before, and I am looking at this book to learn how to create an LLM app. I am really looking forward to trying it out for all three types of apps covered in the book - assistants/chatbot, code generation, and data science. The book is clear and straight to the point, so I expect to be able to try these out fairly quickly. I have gotten through the "setting up the dependencies" section. I cloned the book's github repo, and I tried three methods for variety's sake to create a python environment: pip, conda, and Docker, all on Windows, and I believe I have them all set up. I hit some bumps, but I was able to follow the onscreen error messages and get past them.  For pip, I needed to install MSFT Build Tools to get C++.  For the conda case, I had to modify the yaml file for two of the packages - ncurses and readline, which have different names for Windows. In Chapter 2 there is a comparison of LangChain with other frameworks, from which you get a feel that choosing LangChain at this moment is the best choice. I am happy to have found this book, and I can't wait to proceed w/the next steps. It's a lot of fun to be able to interact w/LLMs.

    A good book, be prepared for extra research.
  

*by D***T on Reviewed in the United States on January 13, 2024*

This is one of the best books on Generative AI (at least developing with/against) that I've seen thus far.  That said, it's not perfect - in fact, kind of far from it.The Good:The first 3-4 chapters (especially the first 3) are a goldmine when it comes to a good landscape view of AI currently.  What I greatly appreciate about this book is that while it still has some focus on OpenAI (through use), it does talk about other models out there.  Way too many books focus on integrating with OpenAI instead of illustrating that you can (and sometimes should) be running your own models.  I found the first 3 chapters to be, by far, the best in the book.  In my opinion, the first three chapters are worth the cost of the book.The Bad:You'll need to be prepared for a lot of extra research.  Starting around Chapter 4, you'll see new syntax and classes used that don't explain _WHY_ they're being suggested.  There's also a good deal of hand waiving in terms of the details for the implementation choices.  Below is an example:On page 158, you'll read about the ConversationalRetrievalChain - which is intended to, given vector store, search against documents loaded in it.  Then, on page 161 you're presented with "ConversationChain".  It mentions that it's to remember past interactions with the LLM, then gives a bunch of code.  It doesn't do anything to contrast the two.In other words, you'll be finding something, noting it down on paper, and finding the distinction yourself (I found myself on a LangChain ticket that explained the difference).The other "bad" about the book is also part "good" too (somewhat).  The Github repo is important to find and pull from.  The code in the book in some cases works poorly, or is missing crucial points that if you type what's presented in the book, you may not get a fully running thing.  So the github repo, grepping through repo looking for the code that best matches what you're reading then copying/pasting is important.  It doesn't help that the Github repo doesn't denote the projects by chapter so it's easier to find the code.  You'll also want to do this anyways, because even in earlier revisions of the code, there were bugs present.  E.g. with the chatbot, multiple "AI" outputs because of the way it was called/instantiated.  To the author's credit, he is making changes and most of them are good (not all, I find myself disagreeing with some of the changes and have multiple versions of his code up since some elements in the older versions are better for learning than the newest code checked on yesterday).The theme in the "bad" is be prepared to search, take notes, and write/highlight in the book.Summary:Despite the negatives, this book is absolutely fantastic and the best that I've found so far.  O'Reilly had the preview version, which I was reading til the full release came out and bought the book too.  I do recommend the book if you want to develop against LLMs - and I also recommend it for the first 3 chapters for more summary information.  Just a few tips:1. Make sure you do as many of your own code examples using what's presented in the book at the Github profile to solidify knowledge.  If you plan to read the book and not implement right away, you'll gain little after Chapter 3.2. Take notes - ample notes, search and contrast.  The name differences between the classes are important, and there's little explanation in the book.  I find myself noting the class names on paper, drawing relationships, and explaining them based off searches (and what little may be in the book that helps).That all said, I do recommend the book.
