Here’s How.\n\n*An approachable, reproducible guide to LoRA, quantization, training loss, validation, and model evaluation.*\n\nWhen I started this project, I wanted more than a better score. I wanted to\n\nunderstand what fine-tuning was actually doing. This guide starts with the basic ideas, explains the vocabulary as it comes up, and uses our real training runs to show what worked and what failed.\n\n*If you are not a paid medium member, u can read it **here*\n\nThe result:after six controlled experiments, validation Macro-F1 rose\n\nfrom0.2956 to 0.8246. Exact-match accuracy reached91.5%, and every\n\nresponse in the 200-example validation set could be parsed.\n\nThis work was built as part of [NVIDIA’s India Agentic AI Open Hackathon](https://www.openhackathons.org/s/siteevent/a0CUP00004gn7e32AA/se000496), where our team, **RTX Renegades** , built **NemoCounsel**, an AI contract review assistant powered by the fine-tuned model described in this post.
