OpenMed Protein NER 108M

OpenMed/OpenMed-NER-ProteinDetect-BioPatient-108M-v1-onnx-android

A 108M BERT model for extracting protein mentions in English clinical and biomedical text.
Runs locally after download on Python CPU, in the browser, and on Android.

Model

OpenMed in Python on CPU

pip install --upgrade "openmed[onnx-runtime]"

from openmed import OnnxModel

model = OnnxModel.from_pretrained("OpenMed/OpenMed-NER-ProteinDetect-BioPatient-108M-v1-onnx-android")
entities = model("HER2 expression was elevated in the tumor.")

for entity in entities:
    print(entity.to_dict())

OpenMed selects the CPU-oriented INT8 graph by default and returns labels, confidence scores, exact character offsets, and source text.

OpenMed in Web

npm install openmed @huggingface/transformers onnxruntime-web

import { loadOnnxModel } from "openmed";

const repo = "OpenMed/OpenMed-NER-ProteinDetect-BioPatient-108M-v1-onnx-android";
const model = await loadOnnxModel(repo);
const entities = await model("HER2 expression was elevated in the tumor.");

The default INT8 path runs with WebAssembly. For WebGPU, select the FP16 graph:

const model = await loadOnnxModel(repo, {
  variant: "fp16",
  device: "webgpu",
});

OpenMedKit for Android

Add JitPack to the consumer application's settings.gradle.kts:

dependencyResolutionManagement {
    repositories {
        google()
        mavenCentral()
        maven {
            url = uri("https://jitpack.io")
            content { includeGroup("com.github.maziyarpanahi") }
        }
    }
}

Use the latest OpenMed build from the master branch:

dependencies {
    implementation("com.github.maziyarpanahi:openmed:master-SNAPSHOT")
}

After downloading this model repository into an app-controlled directory:

import com.openmed.openmedkit.OpenMedKit

OpenMedKit.fromDirectory(modelDirectory).use { model ->
    val entities = model.analyzeText("HER2 expression was elevated in the tumor.")
}

Inference and tokenization remain on-device.

Included Artifacts

All graphs use opset 18, dynamic batch and sequence axes, stable tensor names, and source-text offset metadata.

The OpenMed Ecosystem

This model is part of OpenMed, an Apache-2.0, local-first clinical AI stack:

• 2,000+ medical models for clinical NER, biomedical extraction, and privacy.
• PII detection and de-identification across 55+ identifier types and 17 languages.
• Python, MLX, Swift, Android, React Native, Web, REST, and gRPC runtimes.
• Structured and multimodal intake for OCR, documents, DICOM, FHIR, and HL7.
• Offline and air-gapped deployment with no telemetry by default.

Intended Use and Limitations

This model is intended for extracting protein mentions. It does not diagnose conditions or make clinical decisions. Evaluate recall, thresholds, and span behavior on appropriately governed data before deployment. Local execution supports privacy-preserving workflows but does not by itself guarantee regulatory compliance.

All examples in this card are synthetic.
