How hard is LLMs From Scratch to learn?
Users describe it as intermediate · typically A few hours to read first chapters and run initial code to get going
Where people get stuck
- • Requires PyTorch and Python proficiency
- • Some chapters have missing scripts or API changes needing manual fixes
- • Math background helpful for attention and transformer concepts
Who LLMs From Scratch actually suits
Works well for
- • Developers and researchers who want to understand LLM internals deeply before building their own models
- • PyTorch users with intermediate+ Python skills looking for a hands-on, code-first guide
- • Engineers aiming to fine-tune or modify existing LLMs for specialized tasks
- • Students or self-learners who thrive on build-and-train projects rather than theory-only study
Not the right fit for
- • Absolute beginners to machine learning or those without PyTorch experience
- • Readers seeking a quick overview of LLM concepts—this is a marathon, not a sprint
- • People who want pre-written, copy-paste runnable code without any debugging
- • Those solely looking for API usage tutorials to interact with existing LLMs
What people are discussing right now
