Jev Modernbert

jjshin's full fine-tune of Laya, the ModernBERT-large System-1 decision model, with a 421M encoder and a decision head trained by a hand-written 404-line PyTorch RLCD loop and LBFGS temperature calibration.

A Japanese System One decision model built on modernbert-ja-310m: send text and typed questions and get typed answers with probabilities from one forward pass, no text generation, at 314.6M parameters that also run on a CPU.

Apache-2.0 ModernBERT fine-tune that answers noul, choice, score and multi-label questions with a probability for every option. It serves Jev's POST /v1/systemone locally so TypeSafe's Python SDK runs unchanged, reporting 0.026 expected calibration error on its test split.
