Fine-tuning explained — Further training for a particular task
Continue training an existing model on task-specific data, updating some or all parameters to adapt its behavior.
An everyday example
A team trains on approved support replies to make tone and output format more consistent.
When you’ll encounter it
Consider it for repeated tasks when prompting is insufficient and suitable training data is available.
What to watch for
Uploading a document for a conversation is usually not fine-tuning. Training requires resources and evaluation and does not guarantee complete knowledge or error-free answers.
