MLflow is an open-source platform integrated into Themelio for managing the ML lifecycle. It provides experiment tracking (logging parameters, metrics, and artifacts), a model registry for versioning and staging models, and artifact promotion from training runs directly to the catalogue. MLflow instances are provisioned per project or as secure multi-tenant deployments.
