This piece documents an early fine-tuning experiment centered on information extraction instead of open-ended chat. The goal was to see whether a small language model could be shaped into a focused assistant for structured NER-style tasks without taking on the cost profile of a larger model.
The article is valuable because it stays practical. It focuses on the parts of the workflow that usually determine whether a fine-tuning attempt becomes useful in production: data preparation, output reliability, and evaluating against the exact format the system is expected to return.
