“Jev can't hallucinate”
MisleadingNot yet tested by usJev
The claim
Because outputs are typed, Jev cannot hallucinate.
Our read
It can't return an answer outside the schema you define. It can still pick the wrong answer with high confidence. This was the main argument in the 1,800+ point Hacker News launch thread.
Misleading: The numbers may be real, but the framing or comparison makes them look better than they are.
Test status
We haven't reproduced this yet. When we do, measured accuracy, latency, and cost will appear here next to the claimed figures.
