Leanpub Book Launches
Hosted by Leanpub co-founder Len Epp
In a Leanpub Launch video, Leanpub co-founder Len Epp sits down with an author to launch their new book: what it's about, who it's for, and the story behind writing it. Every Leanpub author can apply to record one, for free.
LM from First Principles
Launched:LM from First Principles is a notebook-driven guide to building and deploying language models from the ground up. Starting from a 9,025-parameter bigram that predicts one character at a time, each chapter adds one layer of capability — feedforward context, sampling strategies, self-attention, scaling — until you have a model you can push to Hugging Face. Every concept is grounded in a runnable Jupyter notebook, so you do not just read about how language models work; you watch them train, fail, improve, and generate. The book is written for practitioners who want to understand what is happening inside the model, not just call an API. You need Python and curiosity. Everything else is built from first principles.

As an academic, I like Leanpub because it lets me write and get my ideas out there quickly. Leanpub is simply the best place for publishing my books.
Leanpub's book-creation tools allowed me to focus on creating the types of books I wanted to write instead of worrying how to create my own book publishing toolchain. I have never regretted using Leanpub to publish my ebooks.
Leanpub takes the pain out of publishing. They provide the tools, you provide the books and then magic happens.
I love using Leanpub because I can write my book using simple Markdown notation. Leanpub lets me focus on my content and they handle the rest.
Leanpub is a game changer for independent authors, removing the hassles associated with formatting, book production, and electronic sales, freeing up the time to do what we do best: write.
Leanpub helped me achieve my goal of publishing a book. Its simple, easy to use interface got my book up and making money within weeks, I love Leanpub!
Leanpub helped me gauge interest in my book, get payments early on when it was only a few chapters, and has got me a bunch of sales just from people browsing around the site.
Leanpub helps me see my books as I write them. Even better, I can find readers early, to read my books and offer suggestions. I can pivot, if I see the need.
Leanpub made it simple for me to run with my book idea and build my reputation in the Ruby community. I went from first draft to first sale in days, not months or years.
Four years ago, I joined Leanpub to just give it a try. Today, over 28,000 book sales later, I cannot help but say that I'm the biggest Leanpub fan on this planet!
Leanpub makes publishing your own book super easy. The fact that you can release updates continually helps with the mindset of getting a minimum version out ASAP and then iterating to improve.
I earn more royalties from my books on Leanpub than I do with well established publishers or through Amazon (which I publish on thanks to Leanpub's mobi conversion).
Leanpub allows me focus on content, takes care everything else and offers an amazing author royalty. It’s a fantastic platform for writing and publishing books.
I love that Leanpub makes writing and publishing a beautiful book so simple. I no longer spin my wheels with layouts and formats - Leanpub gets out of the way when it's time to write, and then automates everything when it's time to publish.
With Leanpub, the first person who purchased my book for $9.99 almost two years ago (and only received a preface, and two short intro chapters) has had access to almost every bit of knowledge I've gained in those two years, and *that's* the value.
Simple and lean, forces me to focus on writing and marketing, and pays excellent royalties.
Leanpub forces you to focus on writing and gives you immediate feedback. Allowing Leanpub to take care of the curation and delivery helped me focus on shipping my book.
While most eBook exporter apps today can generate PDF files and many support ePub, there's one tool we recommend above all after trying 8 of the most popular: Leanpub.
