An open Jev-style LoRA on Qwen3.5-9B from Bespoke Labs, trained on 2,676 contrastively curated examples to score the allowed answer tokens directly for enums, booleans and rubric levels. Recipe, data and a public benchmark suite are released with it.
A ModernBERT-large encoder with an option-marker head. Premise and options are packed into one sequence and each option's marker is scored in a single bidirectional pass; version 1.2 makes the scoring order-invariant.

Questions
What is the difference between bespoke-nimble-9b and von?
bespoke-nimble-9b is from Bespoke Labs and von from wfzyx. bespoke-nimble-9b has open weights and a hosted API; von has open weights you can download and run. Both answer choice, noul, score and classify questions. Only bespoke-nimble-9b answers route. von is the smaller model, at 395M parameters to 9.0B.
Which is more accurate, bespoke-nimble-9b or von?
They report on different suites — bespoke-nimble-9b 90.1% on Bespoke held-out set (324 examples), von 63.9% on JevBench public standard tier — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, bespoke-nimble-9b or von?
bespoke-nimble-9b: Hosted, price not published, or free to self-host. von: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, bespoke-nimble-9b or von?
By their publishers’ figures, von answers in about 18 ms at the median and bespoke-nimble-9b in about 106 ms — measured on different hardware, so treat it as a rough guide.
