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.
FrontiersMind's decision model on a base it pre-trained from scratch. Each question reads the state and its own tokens once and a 256-dimension pointer head scores the options; Choice and Score take up to 255 entries, and nothing is generated.

Questions
What is the difference between laya and lumma-fev?
laya is from Convai Innovations and lumma-fev from FrontiersMind. Both have open weights you can download and run. Both answer choice, score and noul questions. Only laya answers classify and route. lumma-fev reads up to 8K tokens of state, against 512 tokens for laya. laya is the smaller model, at 421M parameters to 649M.
Which is more accurate, laya or lumma-fev?
Only lumma-fev publishes an accuracy figure (64.0% on typed-decisions (maker's table; split not stated)); laya does not, so there is no comparison to make without your own test.
Which is cheaper, laya or lumma-fev?
laya: Free (open weights). lumma-fev: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, laya or lumma-fev?
By their publishers’ figures, laya answers in about 39.5 ms at the median and lumma-fev in about 45.8 ms — measured on different hardware, so treat it as a rough guide.
Can I run laya or lumma-fev locally?
Yes, both: systemone pull convai-innovations/laya and systemone pull frontiersmind/lumma-fev download the weights.
