A/B tests on real conversations

Try a different prompt, first message, model or voice on part of your real conversations, then keep the better one.


  1. Open the agent and go to A/B test.
  2. Choose what variant B changes: the prompt, first message, AI model or voice.
  3. Choose how many new conversations use B, then start the test. A caller stays on the same side for the whole conversation.
  4. Compare A and B side by side, including how often conversations were resolved, how often callers said it helped, and credits used.
  5. Click Use B from now on to keep B, or Stop, keep A to end the test.

Only one test runs per agent at a time. To check a change before real callers hear it, use Tests and Compare.
