Overview

Factuality testing finds AI hallucinations—plausible-sounding but false outputs that erode trust.

With human oversight, you catch and correct errors that automated checks often miss, ensuring your models are reliable and accurate.

Challenge

If AI errors slip through, it can pose major risks, from misinformation to reputational damage and legal liability.

Teams struggle to scale fact‑checking with internal experts alone. This can slow release schedules and leave critical mistakes undetected.
