# FilingTag

**FilingTag** is a small, on-device banking NER model 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:** token-classification
- **Base model:** `answerdotai/ModernBERT-base`
- **Entity types (139):** AccrualForEnvironmentalLossContingencies, AcquiredFiniteLivedIntangibleAssetsWeightedAverageUsefulLife, AllocatedShareBasedCompensationExpense, AmortizationOfFinancingCosts,

- **Held-out F1:** 0.6444
- **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, AutoModelForTokenClassification
tok = AutoTokenizer.from_pretrained("flowxai/filingtag")
model = AutoModelForTokenClassification.from_pretrained("flowxai/filingtag")
```
