Comet Opik is a repository containing two main services: a frontend and a backend. It provides a Python SDK for easy installation. Users can run the full application locally with minikube, following specific installation prerequisites. The repository structure includes directories for applications like Opik backend, with detailed instructions available in the README files. Users can manage the installation using simple k8s commands and interact with the application via URLs for checking the running application and API documentation. The repository aims to facilitate local development and testing of Opik using Kubernetes technology.

🚀 What is Opik?

Opik is an open-source platform for evaluating, testing and monitoring LLM applications. Built by Comet.


You can use Opik for:

  • Development:

    • Tracing: Track all LLM calls and traces during development and production (Quickstart, Integrations
    • Annotations: Annotate your LLM calls by logging feedback scores using the Python SDK or the UI.
  • Evaluation: Automate the evaluation process of your LLM application:

  • Production Monitoring: Monitor your LLM application in production and easily close the feedback loop by adding error traces to your evaluation datasets.


🛠️ Installation

Opik is available as a fully open source local installation or using Comet.com as a hosted solution. The easiest way to get started with Opik is by creating a free Comet account at comet.com.

If you'd like to self-host Opik, you can do so by cloning the repository and starting the platform using Docker Compose:

# Clone the Opik repository
git clone https://github.com/comet-ml/opik.git

# Navigate to the opik/deployment/docker-compose directory
cd opik/deployment/docker-compose

# Start the Opik platform
docker compose up --detach

# You can now visit http://localhost:5173 on your browser!

Opik reports anonymous usage reports to the Opik team to help with the development of new features. No private information is collected, there reports are fully anonymous.

You can opt-out of usage reporting by setting the OPIK_USAGE_REPORT_ENABLED environment variable to false before running Opik locally:

# Start the Opik platform
export OPIK_USAGE_REPORT_ENABLED=false

docker compose up --detach

All usage reports can be found here: Usage Reports

🏁 Get Started

To get started, you will need to first install the Python SDK:

pip install opik

Once the SDK is installed, you can configure it by running the opik configure command:

opik configure

This will allow you to configure Opik locally by setting the correct local server address or if you're using the Cloud platform by setting the API Key

[!TIP]
You can also call the opik.configure(use_local=True) method from your Python code to configure the SDK to run on the local installation.

You are now ready to start logging traces using the Python SDK.

📝 Logging Traces

The easiest way to get started is to use one of our integrations. Opik supports:

Integration Description Documentation Try in Colab
OpenAI Log traces for all OpenAI LLM calls Documentation Open Quickstart In Colab
LiteLLM Call any LLM model using the OpenAI format Documentation Open Quickstart In Colab
LangChain Log traces for all LangChain LLM calls Documentation Open Quickstart In Colab
LangGraph Log traces for all LangGraph executions Documentation Open Quickstart In Colab
LlamaIndex Log traces for all LlamaIndex LLM calls Documentation Open Quickstart In Colab
Ollama Log traces for all Ollama LLM calls Documentation Open Quickstart In Colab
Predibase Fine-tune and serve open-source Large Language Models Documentation Open Quickstart In Colab
Ragas Evaluation framework for your Retrieval Augmented Generation (RAG) pipelines Documentation Open Quickstart In Colab

[!TIP]
If the framework you are using is not listed above, feel free to open an issue or submit a PR with the integration.

If you are not using any of the frameworks above, you can also using the track function decorator to log traces:

import opik

opik.configure(use_local=True) # Run locally

@opik.track
def my_llm_function(user_question: str) -> str:
    # Your LLM code here

    return "Hello"

[!TIP]
The track decorator can be used in conjunction with any of our integrations and can also be used to track nested function calls.

🧑‍⚖️ LLM as a Judge metrics

The Python Opik SDK includes a number of LLM as a judge metrics to help you evaluate your LLM application. Learn more about it in the metrics documentation.

To use them, simply import the relevant metric and use the score function:

from opik.evaluation.metrics import Hallucination

metric = Hallucination()
score = metric.score(
    input="What is the capital of France?",
    output="Paris",
    context=["France is a country in Europe."]
)
print(score)

Opik also includes a number of pre-built heuristic metrics as well as the ability to create your own. Learn more about it in the metrics documentation.

🔍 Evaluating your LLM Application

Opik allows you to evaluate your LLM application during development through Datasets and Experiments.

You can also run evaluations as part of your CI/CD pipeline using our PyTest integration.
