Hey Product Hunt! 👋 After 15+ years building startups and watching AI go from "academic curiosity" to "holy shit this changes everything," I got tired of the gap between buzzword-heavy AI content and actual understanding. What LMPath is (and isn't): - ✅ Technical depth without PhD-level math intimidation - ✅ Built from foundational research papers (Attention Is All You Need, GPT-3, etc.) - ✅ Explains HOW language models work, not just what they can do - ❌ NOT another ChatGPT wrapper or surface-level business guide - ❌ NOT a comprehensive ML course (there are great ones already) What's already working: - 📍 Auto-progress tracking - picks up exactly where you left off - 🌙 Dark mode - because who codes in light mode anyway - 📱 Mobile-responsive - learn on commute, finish on desktop - 🍞 Smart breadcrumbs - never lose your place in complex topics - 📊 Reading progress indicators - see how far through each chapter Current limitations I'm honest about: - Only 2 courses live (Intro to LMs + RAG Systems) - No interactive coding environments yet - Missing some advanced topics like training dynamics - Built by one person (me), so updates take time What's coming soon: - 🔧 Hands-on coding labs - actual implementations, not just theory - 💬 Command system - ask questions directly within lessons - 📚 More courses - Transformers deep-dive, fine-tuning, embeddings - 🎯 Practice problems - reinforce concepts with real scenarios The goal isn't to replace existing resources but fill the gap between "AI is magic" and "here's a 50-page math proof." If you've ever wondered how ChatGPT actually generates text or why RAG systems work, this might click for you. Built this because I needed to understand these systems to make good technical decisions. Maybe it'll help others facing the same challenge. Feedback welcome - especially if something doesn't make sense. That's usually where the best improvements come from.
