Why is version control important in AI?

• A. It increases model accuracy.
• B. It ensures reproducibility and governance.
• C. It reduces data storage needs.
• D. It accelerates inference speed.

Answer: (B)

Version control in AI is about reproducibility and governance. It tracks changes to data, features, training scripts, configurations, and model artifacts over time, creating a complete history of how a model was built and evaluated. This allows you to reproduce results exactly later by locking in the same data snapshot, code, and hyperparameters. It also provides an audit trail—who changed what, when, and why—which is essential for governance, compliance, and collaboration in teams. With branching and merging, you can experiment safely, compare different approaches, and rollback if something goes wrong. While version control doesn’t automatically make a model more accurate or faster, its ability to preserve provenance and control the ML lifecycle is what makes reliable development and accountable deployment possible.
