One of the most powerful features is the ability to create a playground directly from existing LLM spans in your traces. When you click Open in Playground from any LLM span, the playground automatically inherits all the original configurations:
Model settings: The exact model used in the original request
System prompts: Complete message history and system instructions
Input format: The original prompt structure and variables
This eliminates the need to manually recreate complex configurations and allows you to instantly experiment with variations of successful prompts from your traces.
