AI trace

A span hierarchy — client → orchestration → retrieval → model → tool — capturing a single AI request end-to-end, including prompts, responses, tool calls, and token usage.

What this means in practice

The AI trace is the unit of debuggability, audit, and incident reconstruction; OpenTelemetry semantic conventions for GenAI standardise its shape.

Synonyms

GenAI trace , LLM request trace

  • Observability for AI — The set of telemetry — prompt/response capture, retrieval traces, tool-call records, token-cost metrics, and evaluation signals — that makes an AI system operable and auditable.
  • Agent trace — A span hierarchy that captures a multi-step agent execution — loop iterations, tool calls, memory reads and writes — with enough fidelity to reconstruct the agent's full decision path.
  • Replayability — The ability to deterministically reproduce an agent trace given captured inputs — a recorded session, the prompt, the tool responses, the random seed.
