HEAD TO HEAD
Convai Innovations: laya and Featherless AI: simple-jev, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | convai-innovations/laya | featherless-ai/simple-jev |
|---|---|---|
| Summary | An open-weights System One model from Convai Innovations. A fully fine-tuned ModernBERT-large encoder with a from-scratch decision head that scores one marker per option and answers every question in a single 33–39 ms pass. Runs on your own CPU or GPU. | Featherless AI's open server that turns a stock Hugging Face language model into a typed-decision endpoint. It reads the next-token logits for each question and builds the Choice, Score or Noul answer itself; no classifier head is trained and no JSON is generated. |

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.
laya is from Convai Innovations and simple-jev from Featherless AI. laya has open weights you can download and run; simple-jev has open weights and a hosted API. Both answer choice, score, noul, classify and route questions.
Neither publishes an accuracy figure. Test both on your own labelled examples.
laya: Free (open weights). simple-jev: Hosted, price not published, or free to self-host. Open weights cost nothing per call beyond your own hardware.
Yes, both: systemone pull convai-innovations/laya and systemone pull featherless-ai/simple-jev download the weights.
