Route a percentage of requests to a challenger.
Two Models, One Live Test
You have a new model you believe is better. Instead of guessing, you let real traffic decide. An A/B test runs both models side by side on live users. 🔬

The current model in production is your champion. The new candidate you want to prove is the challenger. The test sees if the challenger truly beats the champion.
