Supersonic Labs: julia-1 and Juspay: xor, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | supersonic-labs/julia-1 | juspay/xor |
|---|---|---|
| Summary | 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. | 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. |

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.
julia-1 is from Supersonic Labs and xor from Juspay. Both have open weights you can download and run. Both answer choice, score, noul, classify and route questions. julia-1 is the smaller model, at 144M parameters to 35B.
They report on different suites — julia-1 73.2% on typed-decisions test set (400 cases, 2,000 questions), 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.
julia-1: Free (open weights). xor: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Yes, both: systemone pull supersonic-labs/julia-1 and systemone pull juspay/xor download the weights.
