Version control for models is a critical aspect of machine learning operations (mlOps) that ensures the management and tracking of changes to machine learning models over time. This practice is essential for maintaining the integrity and reproducibility of models, especially as they evolve through various stages of development and deployment.

One effective approach to version control involves using tools like Git and Data Version Control (DVC). Git is utilized for managing code and metadata, while DVC is specifically designed to handle large datasets and model artifacts. This dual-layered version control allows for scalability, security, and the ability to tag and access specific versions of models easily. It also ensures auditability and transparency, which are vital for reproducibility in machine learning projects ¹.

Moreover, version control facilitates collaboration among team members, enabling them to work on the same codebase without conflicts. It allows teams to track changes, review each other’s work, and quickly roll back to previous versions if issues arise during deployment ²³. Overall, implementing version control for models is fundamental to successful machine learning workflows.
