OpenLLMetry (Standalone Instrumentors)

OpenLLMetry is a project name, not a single installable PyPI package. It refers to two related but distinct things that must not be confused: (1) The traceloop-sdk — the high-level Traceloop SDK (already documented separately) that wraps OpenLLMetry auto-instrumentation behind Traceloop.init(). (2) Standalone opentelemetry-instrumentation-* packages — individual OTel instrumentors for specific LLM providers/frameworks, published from the traceloop/openllmetry GitHub monorepo. These can be used WITHOUT traceloop-sdk in any existing OpenTelemetry setup. ECOSYSTEM CONFUSION: There is a second, competing instrumentation ecosystem called OpenInference (from Arize-ai/openinference), which publishes openinference-instrumentation-* packages. Both OpenLLMetry and OpenInference instrumentors instrument the same providers (OpenAI, LangChain, etc.), use different span attribute schemas, and route to different preferred backends. They are NOT interchangeable.
