Build a Reasoning Model From Scratch Is Now on Amazon

Sebastian Raschka's book 'Build a Reasoning Model (From Scratch)' is now available on Amazon, but readers in India are advised to order directly from Manning to avoid counterfeit black-and-white copies sold on Amazon India. Raschka confirmed that Amazon.com copies are genuine and urged readers to leave reviews on Amazon.com to counterbalance fake reviews from Amazon India.

Build a Reasoning Model (From Scratch) is now finally also available on Amazon! Thanks so much to everyone who preordered!

One important note for readers in India: please avoid ordering through Amazon India for now since they are selling counterfeit black-and-white copies. The genuine book is printed in color this time and includes a code for registering the book on Manning’s website. If you are based in India, I recommend ordering directly from Manning. (If you received a counterfeit copy, please return it. I am very sorry about the hassle.)

Unfortunately, these counterfeit sales also directly hurt my work as an independent author. And reviews from readers who received the fake copies from Amazon India also appear on the global Amazon.com page, which makes it look as if the genuine copies on Amazon.com have the same issues.

Based on what I have seen and heard from readers who received the copies from Amazon.com yesterday, Amazon.com itself appears safe.

I also ordered a copy through Amazon.com myself, and I can confirm that it’s genuine.

If you received a genuine copy and have had a chance to read it, I would be very grateful if you considered sharing your experience in a review on [Amazon.com](https://amzn.to/4aAKiFY), even a short one. It would really help, especially since reviews for the fake copies from Amazon India also show up on the Amazon.com page. Thank you!
