Experiments in Traceloop provide teams with a structured workflow for testing and comparing results across different prompt, model, and evaluator checks, all against real datasets. ## What You Can Do with Experiments Execute multiple evaluation checks against your dataset See all experiment run outputs in a comprehensive table view with relevant indicators and detailed reasoning Run the same experiment across different dataset versions to see how it affects your workflow Add a tailored task to the experiment to create evaluator input. For example: LLM calls, semantic search, etc.
