Train Your Own LLM from Scratch
A new open source project on GitHub provides a detailed, step-by-step guide for training a Large Language Model from scratch using PyTorch. The repository includes code and explanations covering everything from data preparation and tokenization to implementing the transformer architecture and the training loop. It is designed as an educational resource for developers who want to understand the inner workings of LLMs.
MY TAKE
This is an incredible resource for demystifying LLMs and moving beyond just using APIs. Understanding the fundamentals of how these models are built is becoming a crucial skill for senior engineers.
