Observability for LLM applications and AI agents, tracing model calls, tool invocations, and agent handoffs.
Honeycomb Agent and LLM Observability reveals agent behavior in production through Agent Timeline, which orders user inputs, model calls, tool invocations, and agent handoffs as they happened. Teams debug nondeterministic failures, trace long multi-turn conversations, and separate problematic behavior with distributed tracing built for AI workflows.
The offering adds SLO-based monitoring tuned for LLM reliability, token usage and health signals, plus BubbleUp anomaly detection and a natural-language query assistant. Engineers improve agent quality with real production data instead of relying on traditional testing that cannot cover generative behavior.
