AI A/B Test Manager Framework for Model Experiments
60% AI projects fail due to poor testing. This framework provides statistical rigor for model comparison experiments with evidence-based deployment decisions.
Implementation Steps
- Define hypothesis with clear success criteria before test launch.
- Configure control and treatment variants with model IDs, prompts, parameters.
- Select primary metric: Quality, Cost, Latency, User Satisfaction, Error Rate.
- Calculate minimum sample size via power analysis (80% power).
- Set significance level: 90% (exploratory), 95% (standard), 99% (critical).
- Monitor daily metrics: control vs treatment comparison, cost analysis.
- Review automated recommendation: Deploy Treatment, Keep Control, Extend Test, Rollback.
