Overview

What is MLflow?

MLflow is an open-source AI engineering platform for tracking experiments, evaluating agents and LLM apps, managing models, and monitoring production systems. It is increasingly relevant to teams moving agents from prototypes into production.

Experiment tracking

MLflow tracks parameters, metrics, artifacts, and runs across experiments.

Agent teams need to compare prompts, models, tools, and datasets over time.

Evaluation workflows

MLflow supports evaluation workflows for ML, LLM, and agent applications.

Repeatable evaluation is the difference between a promising demo and a maintainable product.

Production AI platform

The platform includes model management and operational workflows.

Teams can connect agent experimentation to the broader AI engineering lifecycle.
