Two Live Book Club Q&As on September 3

Author Sebastian Raschka will host two free live Q&A sessions on September 3, 2026, about his new book Build a Reasoning Model (From Scratch), first with Sophia Yang's The AI Book Club at 10 am CT and then with Sage Elliott's AI Book Club at 2 pm CT. Raschka said the sessions may also cover how the new book connects to his earlier Build a Large Language Model (From Scratch), which builds and pre-trains an LLM from the ground up, while the newer book continues with inference-time scaling and reasoning-focused post-training.

Two Live Book Club Q&As on September 3 I’ve been getting lots of nice feedback on my new book, Build a Reasoning Model From Scratch https://amzn.to/4aAKiFY . Thank you I am trying hard to answer all questions readers may have about the book and related topics, whether they come through social media, GitHub, or email. However, I may have missed a few things here and there. I am also looking forward to doing two live Q&As with readers on September 3 The first Q&A is with Sophia Yang’s The AI Book Club https://luma.com/djttn0ah at 10 am CT. A bit later that same day, at 2 pm CT, I’ll join Sage Elliott’s AI Book Club https://luma.com/zjg8jx5e for a second live Q&A. Some readers were also curious about Build a Large Language Model From Scratch , so we may cover how the two books connect. In short, Build a Large Language Model From Scratch builds and pre-trains an LLM from the ground up. The newer book is basically a sequel that continues with inference-time scaling and reasoning-focused post-training. I’m looking forward to hearing which parts readers found most interesting and what questions they have.
