Replay spans

Any span on the LLM Tracing page can be loaded directly into the Prompt Playground for replay and iteration.

All LLM parameters, prompt templates, input messages, variables, and function definitions are automatically populated, so you can replicate the exact call without manual setup. This allows you to iterate quickly, test changes in context, and continuously refine prompts.
