A solo builder says they trained a small GPT-style model from scratch on an NVIDIA 4060 and are now turning the learning process into a website.
The goal is not to compete with ChatGPT or open-source frontier models, but to help others understand how an LLM works beneath the abstractions. The author says the useful material was scattered across papers, repos, videos, articles, and docs, so they are packaging the code, math intuition, visualizations, and explanations into one step-by-step learning path. The site is not public yet; they are seeking the first 10 beta testers for feedback.
