Detecting Hidden LLM Cost Regressions with Span-Level Observability

Teams can hide their LLM cost spikes within an organization's budget—but not from span-level observability. By instrumenting OpenTelemetry with team, feature, and model identifiers, you can detect per-team cost anomalies in real time, catching issues like runaway retry loops that org-level dashboards miss. This level of granularity is essential for cost accountability when scaling LLM applications.
