description MLflow Overview

MLflow is an open-source platform designed to manage the end-to-end machine learning lifecycle. It provides tools for experiment tracking (logging parameters, metrics, and artifacts), model packaging (MLflow Models), and model deployment (MLflow Models serving). By providing a centralized location for all experiments, MLflow helps teams collaborate, reproduce results, and transition models from development to production environments reliably.

help MLflow FAQ

What does MLflow Tracking actually log during an experiment?

MLflow Tracking records parameters, metrics, artifacts, tags, and source information for machine learning runs. A typical scikit-learn or PyTorch run might log hyperparameters, validation accuracy, a model file, and plots into the same run record.

How is MLflow different from Weights & Biases?

MLflow is open source and widely used as a lifecycle framework with Tracking, Models, Model Registry, and Projects components. Weights & Biases is often stronger for collaborative experiment dashboards, while MLflow is common in Databricks and self-hosted MLOps stacks.

Can MLflow serve a trained model as an API?

Yes, MLflow Models can package models in a standard format and serve them through a REST endpoint. It supports popular flavors such as scikit-learn, PyTorch, TensorFlow, and XGBoost.

What is the MLflow Model Registry used for?

The Model Registry tracks model versions, stages or aliases, descriptions, and approval workflows. Teams use it to separate an experimental run from a model that is ready for staging or production.
