Debugging LLM outputs requires robust tracing tools that capture the full request lifecycle, from prompt assembly to tool execution and retrieved chunks. Tools like Helicone, LangSmith, Langfuse, Future AGI, and Braintrust offer varying approaches to this challenge. Key features for effective debugging include the speed of retrieving a specific request's trace, the granularity of information captured (e.g., retrieved context, tool inputs/outputs, token counts), and integration with standards like OpenTelemetry for a unified view across different system components.
