🎉 New: Our semantic conventions are now part of OpenTelemetry! Join the discussion and help us shape the future of LLM observability.

Looking for the JS/TS version? Check out OpenLLMetry-JS.

OpenLLMetry is a set of extensions built on top of OpenTelemetry that gives you complete observability over your LLM application. Because it uses OpenTelemetry under the hood, it can be connected to your existing observability solutions - Datadog, Honeycomb, and others.

It's built and maintained by Traceloop under the Apache 2.0 license.

The repo contains standard OpenTelemetry instrumentations for LLM providers and Vector DBs, as well as a Traceloop SDK that makes it easy to get started with OpenLLMetry, while still outputting standard OpenTelemetry data that can be connected to your observability stack. If you already have OpenTelemetry instrumented, you can just add any of our instrumentations directly.

🚀 Getting Started

The easiest way to get started is to use our SDK. For a complete guide, go to our docs.

Install the SDK:

pip install traceloop-sdk

Then, to start instrumenting your code, just add this line to your code:

from traceloop.sdk import Traceloop

Traceloop.init()

That's it. You're now tracing your code with OpenLLMetry! If you're running this locally, you may want to disable batch sending, so you can see the traces immediately:

Traceloop.init(disable_batch=True)

🪗 What do we instrument?

OpenLLMetry can instrument everything that OpenTelemetry already instruments - so things like your DB, API calls, and more. On top of that, we built a set of custom extensions that instrument things like your calls to OpenAI or Anthropic, or your Vector DB like Chroma, Pinecone, Qdrant or Weaviate.

🔎 Telemetry

We no longer log or collect any telemetry in the SDK or in the instrumentations. Make sure to bump to v0.49.2 and above.

Why we collect telemetry

• The primary purpose is to detect exceptions within instrumentations. Since LLM providers frequently update their APIs, this helps us quickly identify and fix any breaking changes.
• We only collect anonymous data, with no personally identifiable information. You can view exactly what data we collect in our Privacy documentation.
• Telemetry is only collected in the SDK. If you use the instrumentations directly without the SDK, no telemetry is collected.
