Model identity and version must be captured with each turn so behavior, latency, token usage, failures, and regressions can be attributed to the specific model configuration. Request-scoped correlation identifiers must propagate across agent and tool calls so their spans and telemetry remain connected within one distributed trace. OpenTelemetry defines GenAI model attributes and explains that context propagation enables correlation across distributed service boundaries.
