Automatic Llm Span Instrumentation Via Python Opentelemetry Wrapper

Open-source LLM observability — tracing, evaluation, OpenTelemetry, span analysis.

Unique: Specialized auto-instrumentation for LLM APIs (not generic HTTP tracing) that extracts model names and token counts from API responses and embeds them as span attributes, enabling cost and performance analysis without custom parsing

vs others: Simpler than manual OpenTelemetry instrumentation and more LLM-aware than generic Python auto-instrumentation libraries like opentelemetry-instrumentation-requests
