LLMs From Scratch
49 mentions across 3 sources · 73% positive (averaged across 3 sources)
Hacker News, GitHub, Lemmy
What users praise
- • Unmatched depth in explaining transformer internals with code and illustrations
- • Hands-on approach: build and train a GPT-like model from scratch on your laptop
- • Cryptography: clear, step-by-step construction of multi-head self-attention and transformer blocks
- • Strong focus on 'why' behind architecture, not just 'how' to use APIs
What frustrates them
- • High skill barrier: requires intermediate Python and deep learning knowledge
- • Time-consuming to work through fully—not a quick read
- • Some chapter code lacks reproducibility, breaking the 'follow-along' experience
- • Assumes PyTorch comfort; non-PyTorch users face extra friction

Praktika
64 mentions across 5 sources · 36% positive — critical (weighted across 5 sources)
Hacker News, YouTube, Product Hunt, App Store, Lemmy
What users praise
- • Gets shy learners speaking out loud without the pressure of a human partner
- • Unlimited low-stakes conversation reps at roughly $8/month beats private-tutor pricing
- • Tutors remember prior mistakes, so later sessions feel warmer than the first
- • Cross-session memory and adaptive study plan personalise practice over time
What frustrates them
- • Mispronounces French 'est' and reads Japanese kanji and kana incorrectly
- • Can't hold a dialect line — European Portuguese kept reverting to Brazilian
- • Beginner course described as unintuitive and already too advanced for zero-level
- • Push-to-talk listener mishears, and the app ships with no onboarding instructions

Frequently Asked Questions
LLMs From Scratch vs Praktika: which should you choose?
Praktika and LLMs From Scratch are incomparable products serving different needs. For personalized language speaking practice with AI tutors and real-time correction, choose Praktika. For a deep dive into building a GPT-like LLM from scratch with PyTorch code, choose the book by Sebastian Raschka. Your choice depends entirely on whether you want to learn a language or build an LLM.
Are these tools comparable?
No. Praktika is a language-learning app focused on speaking practice; LLMs From Scratch is a technical book on building LLMs.
Which one is more expensive?
LLMs From Scratch is a one-time book purchase (~$40-60). Praktika is freemium with a possible subscription for premium features (ongoing cost).
Can I use Praktika to learn how to build an LLM?
No. The latest news doesn't mention any such feature; it's purely a language learning tool.
Can LLMs From Scratch help me learn a new language?
No. The book focuses on building LLMs, not language learning.
Which tool is better for a complete beginner in coding?
Neither is ideal for absolute beginners. LLMs From Scratch requires Python and deep learning basics. Praktika might be suitable for beginners in language learning with its native language interface.
Does Praktika support multiple languages?
Yes, it supports multiple languages with distinct AI tutor personas.
Does LLMs From Scratch require prior knowledge of PyTorch?
It's helpful but not mandatory; the book covers concepts step by step.
Are there any updates to LLMs From Scratch from recent news?
The news shows related projects (NanoEuler, vintage LLM) but no direct update to the book itself.
