Adjust an editable agent’s response settings when its replies need different wording or length. Fine tuning here changes how the model generates replies; it does not train a new model or supply facts. Start with clear instructions and useful knowledge. If the problem is a missing business fact, check the source in Knowledge before changing response settings.

​
Find the response settings

  1. Open Home.
  2. Select the intended agent.
  3. Open Build → Settings.
  4. In Agent Builder, select Fine Tune Agent under Fine Tuning Settings.
If the menu is already open, continue with Choose a starting point. Home opens your current space so you can select your own agent.

​
Choose a starting point

The Presets menu applies a group of settings: For a first FAQ assistant, begin with General Use or try Precise. Note the current preset and values before changing them. A preset changes multiple controls together; an individual slider lets you compare one change at a time.

​
Understand the main controls

Use instructions to request a concise style and leave enough response budget for the agent to finish the task.

​
Make one adjustment and compare

For a fictional shop helper whose answers are too long, first try an instruction such as “Keep ordinary FAQ answers concise.” Use Write your agent’s instructions for that change. If you still need a firmer response budget:
  1. Note the current Max Length value.
  2. Move the Max Length slider to a modestly lower value.
  3. Pause to let the change save.
  4. Close the menu.
  5. Ask the same representative question in a fresh preview conversation.
  6. Check that the reply is useful and finishes its answer.
Use the chat beside the Build settings, or select Chat Preview within Build on a narrow screen. Test your agent while you build explains how to compare replies with your sources. Change one setting at a time. If the new budget cuts off the reply, return to Fine Tune Agent and increase Max Length, then try the question again.

​
Use advanced settings only for a specific need

Show Advanced Settings reveals more controls: For a first FAQ-style agent, keep the output limiter enabled when it is shown unless you need the model’s full output length. It is not offered for every model.

​
Confirm the saved settings

Parameter changes save after a brief pause; closing the menu also sends any pending changes. There is no separate Design Save Changes step for this menu. To check the changed value, return to Home, reopen the same agent and open Build → Settings → Fine Tune Agent. Confirm the value you changed remains. If replies become too varied, restore the prior settings you noted or try Precise. If replies stop unexpectedly, check Max Length and unintended Stop Sequences. These controls do not enable extended thinking or outside-app actions. If the underlying model does not suit the job, use Choose your agent’s AI model.
