Welcome to the Comet Docs!

Data science and machine learning teams use Comet’s ML platform to track, compare, explain, and optimize their models across the complete ML lifecycle – from managing experiments to monitoring models in production.

Get Started Watch Demo

Get started with two lines of code¶

# Get started in a few lines of code
import comet_ml

comet_ml.login()
exp = comet_ml.Experiment()

# Start logging your data with:
exp.log_parameters({"batch_size": 128})
exp.log_metrics({"accuracy": 0.82, "loss": 0.012})

Build Better Models Faster

Comet’s machine learning platform tracks the lifecycle of a model in one user interface, so you can build, collaborate, and iterate faster. For enterprise, bring Comet to what you build; we treat virtual private cloud (VPC) and on-premises environments as first-class citizens.

Track models and training runs

Start managing experiments using the tools, libraries, and frameworks you use today.

Tracking a training run Integrations with machine learning frameworks Training models in notebooks

Custom visualizations for faster iteration

Iterate, debug, and evaluate models faster with custom visualizations you can build yourself or choose from our library of templates.

Using Comet's built-in visualizations Creating custom visualizations Comparing training runs

Reproduce experiments

Create dataset versions and track hyperparameters for faster and easier reproducibility and collaboration.

Getting started with artifacts Using remote and local artifacts

Model Registry

Save model versions and deploy registered models using your computing environment.

Python Panel

Python Panels allow you to create your own custom visualization in Python. If we don't the visualization you need, just add it!

Quickstart

Comet's LLMOps suite of tools allows you to explore LLMs through our plaground as well as track and visualize LLM chains.

Kubeflow

The Kubeflow integration allows you to track the status of the DAG and individual steps straight from the Comet UI.
