How to Train Your GPT: Comprehensive Commented Training Guide

How-to-train-your-GPT presents a fully commented codebase for LLM training, making the mechanics of model training accessible to practitioners. By explaining every line of code, this resource bridges the gap between theoretical understanding and practical implementation, enabling developers to understand what happens during the training process.

For the local LLM community, understanding model training is increasingly valuable as fine-tuning and custom model development become practical options. Rather than always relying on pre-trained models from major labs, teams can now cost-effectively fine-tune existing models on specialized data or train smaller models optimized for specific tasks and hardware constraints.

This educational resource contributes to the democratization of LLM capabilities. As more developers understand training fundamentals, the ecosystem will produce more diverse models optimized for specific use cases—including highly specialized models ideal for local deployment where inference cost and performance matter significantly.
