# IntentRouter

**IntentRouter** is a small, on-device healthcare text classifier from the FlowX **OpenNER** family. Developed by **FlowX.AI**. Runs 100% on-premise / air-gapped, so no data leaves your boundary.

## What it does
- **Task:** text-classification
- **Base model:** `answerdotai/ModernBERT-base`
- **Classes (8):** REFILL_REQUEST, NEW_PRESCRIPTION, STOCK_ORDER, RETURNS_REBATE, DELIVERY_ISSUE, BILLING_QUERY, CLINICAL_URGENT, GENERAL_ADMIN
- **Held-out F1:** 1.0000
- **Runtime:** CPU, Apple Silicon, one GPU, or browser/edge via ONNX (INT8). ~100-160 ms/doc on CPU.

## Why a small model
Fine-tuned encoders match or beat frontier LLMs on structured, convention-bound extraction, at a fraction of the latency and cost, with **zero data egress**. Identifiers are validated by checksum (IBAN mod-97, card Luhn, ISIN/LEI, container ISO-6346, VIN, national IDs), a correctness guarantee general LLMs lack. See the FlowX OpenNER benchmark for measured results.

## Usage
```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
tok = AutoTokenizer.from_pretrained("flowxai/intentrouter")
model = AutoModelForSequenceClassification.from_pretrained("flowxai/intentrouter")
```
