MLflow
experiment tracking model management evaluation and tracing
Why learn MLflow?
Makes runs, artifacts, and evaluation evidence easier to compare. Tracking a run does not by itself establish model quality or reproducibility.
Where it came from
MLflow provides tools for tracking experiments, managing models, and evaluating AI applications. Its documentation covers both traditional machine learning and generative AI workflows.
Build your understanding
Work through these exercises in order. Try the task before opening a reference.
- Log parameters and metrics for a baseline run.
- Attach a model artifact and dataset identifier.
- Compare two runs using a fixed evaluation set.
- Record a model's input and output contract.
- Reproduce a saved result from its recorded environment.

Real World Example
Automated Retail Demand Forecasting Lifecycle
A regional grocery chain managing inventory across hundreds of locations.
The business problem
Data scientists struggle to reproduce model versions, leading to inconsistent inventory predictions and stock-outs because experiment parameters are tracked manually in spreadsheets.
How this topic solves it
MLflow provides a centralized platform to log experiment parameters, capture model artifacts, and manage the lifecycle of forecasting models through a unified registry, ensuring full auditability.
- Initialize an MLflow experiment to group related forecasting runs.
- Log hyperparameters and metrics during model training to ensure reproducibility.
- Register the best-performing model version in the Model Registry for staging.
- Use MLflow Tracing to monitor the inference pipeline for unexpected data drift.
- Promote the validated model to production status within the registry.
This diagram illustrates the progression of a model from experimentation to production deployment.
Stores parameters and metrics
Manages model versions
Serves model predictions
- Training Script → logs data → MLflow Tracking
- MLflow Tracking → registers artifact → Model Registry
- Model Registry → deploys version → Production API
Expected business outcome
Improved consistency in inventory forecasting and a clear, auditable history of every model version deployed to production.
Limitations and checks
The centralized Model Registry can become a bottleneck if access controls are not strictly defined; check for unauthorized model transitions by auditing the registry event logs.
