Andy Zhang: ajev and Convai Innovations: laya-multilingual-noulxp, compared on what they decide, where they run, what they cost and what their publishers report.

| Summary | An open Jev-style decision model by Andy Zhang: a LoRA adapter on Gemma 4 26B-A4B (also on Gemma 4 12B) that reads a state and returns a temperature-calibrated probability for every option of a yes/no, choice or score question in one forward pass. | Unofficial NoulXP package of Convai Innovations' Laya multilingual (Apache-2.0), fp32-o23: checked against the model's own answers, none changed. Not made by Convai Innovations. |

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.
ajev is from Andy Zhang and laya-multilingual-noulxp from Convai Innovations. Both have open weights you can download and run. Both answer choice, score and noul questions. Only laya-multilingual-noulxp answers classify and route. laya-multilingual-noulxp is the smaller model, at 322M parameters to 26B.
Neither publishes an accuracy figure. Test both on your own labelled examples.
ajev: Free (open weights). laya-multilingual-noulxp: Free (open weights). Open weights cost nothing per call beyond your own hardware.
By their publishers’ figures, laya-multilingual-noulxp answers in about 44.9 ms at the median and ajev in about 49 ms — measured on different hardware, so treat it as a rough guide.
Yes, both: systemone pull andy-zhang/ajev and systemone pull convai-innovations/laya-multilingual-noulxp download the weights.
