Fine-tuning

You might say

Support replies keep changing tone and format. Should we train a model?

Continuing to train an existing model with task examples so its outputs better match them on a specific taskA support team wants every refund reply to state the outcome before the next step. Fine-tuning can continue training a model with representative inputs and target replies; compare it on tickets not used for training to see whether it helps, and still provide the current task instructions.

Fine tuning

What does fine-tuning change in a support task?

Support · refund question

Support ticket · teaching exampleGoal: outcome first, next step second

Customer messageThe cup is unopened. Can I return it?

Current replyFind the return option on the order page. Unused products can be returned.

Teaching example: the team names a concrete difference—the reply should state the outcome before the next step.

How to tell whether fine-tuning helped

Examples show the target behavior: Representative inputs and target outputs provide examples for further training. There is no single sample count that fits every model and task.

Evaluate on new inputs: Training examples do not prove that new requests will work. Keep tickets outside the training set and compare correctness, format, and tone.

Quick checkChoose the best answer

A team configured a support model. Which evidence shows this request actually used a fine-tuned model?

You can say this to an AI Agent

Do not start training yet. First use real support tickets and target replies to improve the prompt, then check tone and format on a separate set of tickets. If it is still inconsistent, explain what data fine-tuning would use, how you would evaluate it, and what it cannot guarantee.
