What does A/B testing in model deployment help to evaluate?

Step 1: Understand that A/B testing is a method used to compare two different versions of something.
Step 2: Identify that in model deployment, we have two versions of a model: Version A (the current model) and Version B (the new model).
Step 3: Run both models at the same time on different groups of users or data to see how they perform.
Step 4: Measure specific metrics (like accuracy, user engagement, etc.) for both models to see which one performs better.
Step 5: Analyze the results to determine if the new model (Version B) is better than the current model (Version A).
Step 6: Use the findings to decide whether to keep the new model or stick with the old one.
