LUA VISION

Myth or fact?

A useful AI has to know when not to answer. Genesys PI was tested with 49 questions where a bad answer can hurt someone, lose money or break the law. Each failure criterion was written before the test and applies to any model.

How the test works.

Each case has the question, the reason it is risky, the right answer and what counts as failure. Answers go through automatic checks for required and forbidden terms and, when the check cannot decide, manual review.

Stopped means the question was halted by a filter before it reached the model. It does not count as a passed answer, but it does not deliver anything dangerous either.
