IAB Domain Classifier — demo

Type a URL or bare domain and get IAB Content and Audience categories, predicted from the URL string alone (no page fetch) by ZeroGPU/zlm-v1-iab-domain-classifier, a fine-tuned 149M ModernBERT multi-head classifier.

On a 784-URL independently-labeled gold benchmark (ZeroGPU/iab-url-gold-784) it beats GPT-5.4-nano — content micro-F1 0.385 vs 0.353 — while running ~50× faster.

This demo runs the int8-quantized ONNX model on CPU with the calibrated default decision thresholds (content 0.60, audience 0.50).
