Define treatments and metrics
Specify the feature variants to compare, the success metric (task success rate, revenue, etc.) and the observation window used for evaluation.
Run A/B tests for AI features. Compare feature variants fairly.
An A/B testing platform organises controlled comparisons between feature variants to measure user impact and business metrics. Key elements are clear treatment definitions, consistent logging, statistically sound comparison metrics and mechanisms for rollback when a variant degrades behaviour or cost.

An A/B testing platform organises controlled comparisons between feature variants to measure user impact and business metrics. Key elements are clear treatment definitions, consistent logging, statistically sound comparison metrics and mechanisms for rollback when a variant degrades behaviour or cost.
A proposed application: run controlled feature rollouts that compare live model behaviour and key business metrics (e.g. task success rate, latency, cost). This project outlines a prototype workflow; connecting to live traffic and business metrics is a planned extension and not provided by the starter.
Specify the feature variants to compare, the success metric (task success rate, revenue, etc.) and the observation window used for evaluation.
Replace the synthetic data with structured experiment logs that include user id, treatment assignment, inputs, outputs and outcome labels for analysis.
Fit a simple baseline to predict the outcome per-assignment to check for covariate imbalance and to estimate expected effect sizes before full rollout.
Use statistical tests, confidence intervals and A/B-specific metrics such as uplift; add monitoring for logging loss, drift and treatment assignment bugs.
The supplied starter code generates a synthetic binary classification dataset with sklearn.make_classification, builds a Pipeline with StandardScaler and RandomForestClassifier, splits the data, trains the model and prints a classification report. It does not implement experiment logging, treatment assignment, uplift estimation, statistical tests or a deployment/dashboard for A/B tests.
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)The code uses synthetic classification data and only trains a predictive model; it does not ingest experiment logs, assign treatments, compute uplift or run A/B statistical comparisons. The single offline classifier and its report do not validate an A/B testing workflow or measure business impact in production.
Proposed extension: ingest experiment logs with user and treatment identifiers, compute per-treatment metrics and uplift with proper significance testing, and expose results via a dashboard and an API for rollouts and rollbacks.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
