The premise
Agent A/B testing requires methodology adapted to non-deterministic outputs and trajectory-level evaluation.
What AI does well here
Test on representative real traffic, not synthetic
Define success metrics that match user outcomes (not just intermediate signals)
Run long enough to capture variance in agent behavior
Maintain user experience parity across variants (no degraded variant should hit users disproportionately)
What AI cannot do
Substitute A/B testing for actual quality measurement
Predict agent variance in advance
Eliminate the cost of running experiments
Practice this safely
Use a small project example from your own work. The useful move is to compare the AI's draft against your goal, sources, and constraints before you trust it.
Ask AI to explain A/B testing in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "A/B Testing Agents in Production" and ask for two possible next steps plus one reason each step might be wrong.
Check agent improvement against a trusted source, teacher, adult, expert, or original document before you use it.

Hide uncertainty so the final answer looks cleaner
Use private or sensitive details before checking permission
How should AI output about A/B testing be treated?
As proof that no other source is needed
As a replacement for context, consent, or expert review
As a draft or helper output that still needs human judgment and verification
As something that becomes correct when it sounds confident
Name one way to verify an AI answer about A/B testing.
