Use it only when preview behavior is intentional, for low-risk experiments and threshold calibration rather than a pinned production route.
How to evaluate it
Run jev-preview and jev-1.13.0 on the same sample set. Record the response model, probabilities, latency, and billing before comparing thresholds.
What to check before integration
Use the exact jev-preview ID. The official page currently shows it pointing to the same version as jev-latest; aliases can move, so recheck before production use.
Client configuration
