Metask Lab's calibrated decision model in 16 languages. Qwen3.5-4B with a merged LoRA trained with the Nimble candidate-logit objective; one forward pass and a softmax over at most 26 answer-letter logits, with one temperature per question type.
Juspay's open decision model. Qwen3.6-35B-A3B with a merged rank-16 LoRA, shipped with a pinned SGLang serving bundle that answers Choice, Score and Noul questions over text, images or a video through a TypeSafe-compatible /v1/systemone API.

Evaluation suite
JevBench v1.2 public set (231 items) at 4,096 tokens, maker's run
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.
Questions
What is the difference between metask-jev and xor?
metask-jev is from Metask Lab and xor from Juspay. Both have open weights you can download and run. Both answer choice, score, noul, classify and route questions. metask-jev is the smaller model, at 4.5B parameters to 35B.
Which is more accurate, metask-jev or xor?
They report on different suites — metask-jev 80.1% on JevBench v1.2 public set (231 items) at 4,096 tokens, maker's run, xor 90.0% on JevBench public set (231 items), maker's self-run of Xor 1.2 — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, metask-jev or xor?
metask-jev: Free (open weights). xor: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, metask-jev or xor?
By their publishers’ figures, metask-jev answers in about 62.8 ms at the median and xor in about 69 ms — measured on different hardware, so treat it as a rough guide.
Can I run metask-jev or xor locally?
Yes, both: systemone pull metask-lab/metask-jev and systemone pull juspay/xor download the weights.
