What it is
A TypeScript client for Laya, an open-source Jev-compatible System-1 decision model by Convai Innovations. It lets Node.js developers get calibrated probabilities for choice, score, and noul questions on a given state without Python or PyTorch.
How it uses Jev
Jev makes decisions by taking a state (ticket, email, JSON) and typed questions (choice, score, noul). The result is returned in one forward pass with calibrated probabilities. In code, you call laya.systemOne(state, questions) and access answers like result.answers.department.choice or result.answers.churn_risk.noul.
Primitives:choicescorenoul
Technique worth stealing
Batching all questions of one systemOne call into a single ONNX forward pass for efficiency.
Try it
npm install @receptron/laya, then use Laya.load() and laya.systemOne().
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
