Laya is an open-weights (Apache 2.0) encoder-based decision model family from Convai Innovations. Built on ModernBERT-large (421M params) and mmBERT-base backbones, it reads a state (text/JSON/email) plus typed questions and returns calibrated typed answers plus probabilities without any text generation. Checkpoints include English, multilingual (100+ languages), and a fine-tuned typed-decisions variant; a script router dispatches automatically. Released days after the closed Jev model, it is designed for fast local routing, guardrails, triage, and classification tasks.
