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 144M-parameter System One model on the multilingual mmBERT-small encoder. Takes a state, a question and 2 to 20 options and returns one decision with probabilities for choice, score and yes/no questions, on a CPU.

Questions
What is the difference between bespoke-nimble-9b and julia-1?
bespoke-nimble-9b is from Bespoke Labs and julia-1 from Supersonic Labs. bespoke-nimble-9b has open weights and a hosted API; julia-1 has open weights you can download and run. Both answer choice, noul, score, classify and route questions. julia-1 is the smaller model, at 144M parameters to 9.0B.
Which is more accurate, bespoke-nimble-9b or julia-1?
They report on different suites — bespoke-nimble-9b 90.1% on Bespoke held-out set (324 examples), julia-1 73.2% on typed-decisions test set (400 cases, 2,000 questions) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, bespoke-nimble-9b or julia-1?
bespoke-nimble-9b: Hosted, price not published, or free to self-host. julia-1: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run bespoke-nimble-9b or julia-1 locally?
Yes, both: systemone pull bespoke-labs/bespoke-nimble-9b and systemone pull supersonic-labs/julia-1 download the weights.
