The LLM Playground provides an interactive environment for testing your AI agents without making actual web or phone calls. It enables:
  • Rapid prototyping and debugging of agent responses
  • Testing different conversation scenarios
  • Immediate feedback on agent behavior
  • Faster development iterations

​
How to Use

1

Access the LLM Playground

  • Navigate to your agent’s detail page
  • Click the Test LLM tab
  • Choose Manual Chat
You’ll see a chat interface ready for testing.
2

Test basic conversations

Type your message in the input field and observe the agent’s response.
3

Test function calling

Use prompts that should trigger specific functions. Verify that functions are called with the correct parameters.
4

Test dynamic variables

Use dynamic variables in your prompts. Verify that variables are properly interpolated and test different variable values.
5

Mock custom functions

Add a mock response for functions during testing. The mock response is returned instead of making a real function call, ensuring no actual execution occurs during tests.
6

Iterate and refine

Monitor agent behavior and responses. Update prompts or functions as needed, then click Delete to reset the conversation and test the updated behavior.
7

Save test cases

Click Save to store your test conversation. Add a descriptive name — saved tests are accessible from the agent detail page for future regression testing.

​
Best Practices

  • Start with simple conversations and gradually test more complex scenarios
  • Save important test cases for regression testing
  • Test edge cases and error handling
  • Document unexpected behaviors for future reference
