Alibi Serikbay: jevk5 and EldanRing: winnow, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | alibi-serikbay/jevk5 | eldanring/winnow |
|---|---|---|
| Summary | Qwen3.5-4B with a merged rank-16 LoRA distilled from 17,408 teacher questions and 30,000 public training rows, read out as a temperature-scaled softmax over answer-letter logits. Also in 9B, 2B and GGUF. | A Gemma 4 12B fine-tune for typed decisions that also chats and reads images. Ships as GGUF for llama.cpp, holds a 64K context on a 16 GB GPU, and serves /v1/systemone next to /v1/chat/completions. |

Figures are from each model’s manifest; accuracy and latency are what the publishers report, on their own suites and hardware. Add a third model.
jevk5 is from Alibi Serikbay and winnow from EldanRing. Both have open weights you can download and run. Both answer choice, score, noul, classify and route questions. jevk5 is the smaller model, at 4.0B parameters to 12B.
They report on different suites — jevk5 78.4% on JevBench public hard tier, winnow 85.7% on JevBench public subset (231 items), Q8_0 — so the numbers do not rank them. Test both on your own labelled examples.
jevk5: Free (open weights). winnow: Free (open weights). Open weights cost nothing per call beyond your own hardware.
By their publishers’ figures, jevk5 answers in about 13.2 ms at the median and winnow in about 143 ms — measured on different hardware, so treat it as a rough guide.
Yes, both: systemone pull alibi-serikbay/jevk5 and systemone pull eldanring/winnow download the weights.
