Fine-tuned a 2B LLM on WhatsApp group chat, shared the cookbook on GitHub

I fine-tuned a 2B LLM on our WhatsApp group chat, and shared how to do it on GitHub as a cookbook.

Someone fine-tuned a 2B LLM on WhatsApp group chat data and open-sourced the full pipeline as a GitHub cookbook. The post body is blocked by Reddit, so no details on base model, training cost, or results. Title confirms the data source (group chat), model size (2B), and goal (mimic chat style). Good starting point if you want to train a small model on your own chat logs.
