Fine-Tune a Language Model on Your Own Data with LoRA

Fine-tuning teaches a model your tone, format or domain. LoRA makes it affordable by training only a small set of extra weights.

Prepare Your Data

Collect a few hundred high-quality examples in a consistent prompt and response format. Quality matters more than quantity.

Train with LoRA

Load a small open model, attach LoRA adapters, set a low learning rate and train for a few epochs while watching the validation loss.

Test and Compare

Run the tuned model against the base model on questions it has never seen, and keep the adapter only if it clearly wins.
