+# CvNER
+
+**CvNER** is a small, on-device cross 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 (8):** DEGREE, EMAIL, EMPLOYER, INSTITUTION, PERSON, PHONE, SKILL, TITLE
+- **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, AutoModelForTokenClassification
+tok = AutoTokenizer.from_pretrained("flowxai/cvner")
+model = AutoModelForTokenClassification.from_pretrained("flowxai/cvner")
+```
+
+## License & attribution
+Licensed under the **Apache License 2.0**. Copyright 2026 **FlowX.AI** (https://flowx.ai). See the `NOTICE` file. Trained on synthetic, checksum-validated data.
+
+_Part of the FlowX OpenNER model family. Synthetic-data F1 reflects an in-distribution synthetic distribution; validate on real documents before production use._
