Ran @typesafeai's Jev against an existing classifier eval that previously used Gemini 2.5 Flash Lite. It won both on quality (saturated the eval) and speed (6x)
Cookbook: Self-Consistency for Nouls
A 14-Noul claims-triage rubric over one insurance claim, repeated 15 times: mean probability standard deviation of 0.0102 at 111 ms per call, with a 0.30 to 0.70 band for human review.

Highlights
- 14 Noul questions across 15 repeats and 9 conditions; jev-1.13.0 ran at 111 ms and $0.000043 per rubric call.
- The covered answers spanned 0.43 to 0.53, crossing the 0.5 threshold, while the other 13 questions stayed on one side.
- A 0.30 to 0.70 band maps probabilities to no, uncertain, and yes for human review with no extra API call.
Watch out
The band is illustrative rather than calibrated, and values near its edges can still flip between uncertain and a hard answer.

Semantic search over GitHub's Terms of Service: one request ranks all 218 lines with a Choice while a Noul checks whether the document contains an answer at all, including when it should say no.

A two-stage extraction cascade: a mini model extracts, a Noul battery verifies each field in one request, and a 0.7 gate escalates to a reasoning model, sitting on the cost/quality frontier.
