description: Add fast, local, typed decisions to any project with Laya, an open-source non-generative decision model (pip install laya). It classifies, routes, scores and answers yes/no questions about a piece of text, returning calibrated probabilities in roughly 20-35 ms on a laptop GPU, with no LLM call and no data leaving the machine. Use this skill whenever the user wants to classify or route text, triage tickets or emails, detect spam, phishing, toxicity or intent, put a guardrail in front of an agent or LLM, score something against a rubric, or replace an LLM-based classifier to cut latency or cost. Also use it when they mention Laya, Jev, a "System 1 model", "typed decisions" or a "decision model", even if they never name Laya.

# Integrating Laya

Laya answers typed questions about a piece of text. You give it a `state` (the text) and a dict
of questions; it returns a probability for every option of every question in one forward pass.
It never generates text, so it cannot answer off-schema, and it is small enough (322M-421M
parameters) to run inside the user's own process.

Reach for it when the project needs a **decision**, not a sentence: which queue, is this spam,
how urgent, should the agent stop. Do not reach for it when the task needs reasoning over
several steps, arithmetic, extraction of free-form values, or any generated text. For those,
keep the LLM and use Laya in front of it as a cheap first pass (see "Cascade" below).

## Install and first call

```bash
pip install laya        # pulls torch, transformers, safetensors, huggingface_hub
```

```python
import laya

agent = laya.load("convaiinnovations/laya")          # English checkpoint

result = agent.predict(
    {"subject": "Charged twice", "body": "Refund the duplicate today or we cancel."},
    {
        "department": {
            "type": "choice",
            "instructions": "Which department should handle this request?",
            "criteria": {
                "billing": "invoices, payments, refunds",
                "technical": "bugs, outages, system errors",
                "other": "everything else",
            },
        },
        "urgency": {
