Fine-Tuning

Fine-tuning takes a pre-trained large language model and trains it further on a smaller, task-specific dataset so it performs better at a particular job. Methods range from full fine-tuning, which updates every parameter, to efficient approaches like LoRA and QLoRA that modify only a fraction of weights. Also known as: Model Fine-Tuning.
