Yuichi Tateno (hotchpotch): bekko-system-one and Convai Innovations: laya-noulxp-cpu, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | hotchpotch/bekko-system-one | convai-innovations/laya-noulxp-cpu |
|---|---|---|
| Summary | Ultra-small English encoders (17M, 68M and 395M) fine-tuned from Ettin rerankers. Each answers choice, noul and score questions with a probability per candidate and no generated text. Experimental v0 by one developer; the weights have no licence assigned yet. | Unofficial NoulXP package of Convai Innovations' Laya (English) (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.
bekko-system-one is from Yuichi Tateno (hotchpotch) and laya-noulxp-cpu from Convai Innovations. Both have open weights you can download and run. Both answer choice, noul and score questions. Only laya-noulxp-cpu answers classify and route. bekko-system-one is the smaller model, at 395M parameters to 421M. bekko-system-one is licensed other; laya-noulxp-cpu, apache-2.0.
Neither publishes an accuracy figure. Test both on your own labelled examples.
bekko-system-one: Free (open weights). laya-noulxp-cpu: Free (open weights). Open weights cost nothing per call beyond your own hardware.
By their publishers’ figures, bekko-system-one answers in about 5 ms at the median and laya-noulxp-cpu in about 116 ms — measured on different hardware, so treat it as a rough guide.
Yes, both: systemone pull hotchpotch/bekko-system-one and systemone pull convai-innovations/laya-noulxp-cpu download the weights.
