An in‑car system using generative AI (Gemini and Claude) for hundreds of millions of records and ~100k users requires strict output reliability, so the team avoids fully automated tests due to API cost and flakiness. They run Gemini and Claude in parallel with a cross‑reference check that only returns answers when models agree, focus testing metrics on outliers and precision, detect country‑specific biases, create example‑mapping prompts, and set release criteria based on daily user feedback rather than fixed benchmarks.
