What is LLM Observability?
LLM Observability
LLM Observability is the continuous tracking, tracing, and monitoring of Large Language Model inputs, token latency, tool execution chains, prompt drift, and output quality across production AI applications.
Detailed Deep Dive
LLM Observability equips engineering teams with granular visibility into production AI behavior. By capturing full execution traces—including prompt templates, retrieved vector chunks, tool call payloads, and model completion tokens—observability platforms enable real-time latency monitoring, cost allocation, and automated regression detection.
Frequently Asked Questions
Q:What metrics are tracked in LLM observability?
Key metrics include Time-To-First-Token (TTFT), tokens-per-second, prompt cost, hallucination rates, tool invocation latency, and user feedback signals.
Q:How does LLM observability differ from traditional APM?
Traditional APM tracks CPU, RAM, and HTTP status codes, whereas LLM observability evaluates probabilistic model outputs, prompt structures, token counts, and multi-agent execution traces.
