Fine-tuning
Adjusting a pre-trained AI model's weights on a smaller, specialised dataset so it performs better on a specific task.
Browse all definitionsIn detail
Fine-tuning takes a pre-trained foundation model and continues training it on a smaller dataset specific to your domain or task. The result is a model that retains general knowledge but is better at, for example, classifying support tickets, drafting in your house style, or generating outputs in a specific format. Modern lightweight fine-tuning techniques such as LoRA and QLoRA make this affordable for small businesses, where full fine-tuning was previously cost prohibitive.
