Jev now has an open competitor from an actual lab Maincode just released Matilda Jev: a 26B decision model trained on their own infra in Australia. it doesn’t generate text. give it a decision and you get probabilities for every option in one pass. they claim it beats the original Jev on 27/43 benchmarks and the whole thing is open source under Apache 2.0. Open decision models just keep leveling up.
