Jev went closed-source, so devs vibe-cloned open alternatives like Laya in hours

A repost notes Jev is now closed and paid, but AI can vibe-clone almost anything in hours, with a list of open-source Jev alternatives.
The linked project is Laya on GitHub (8.6k stars): a multilingual, non-autoregressive System 1 decision engine that emits typed decisions (choice/score/noul) over 100+ languages in a single forward pass — 33ms per question, 7.2ms/question batched on a T4. No text generation means nothing to parse and nothing to hallucinate. Trained with RLCD (RL against strictly proper scoring rules), it ships three checkpoints plus a per-request Router (421M ModernBERT-large English, 322M mmBERT multilingual, typed-decisions variant). Install via pip install laya.
