Two new bidirectional encoders (230M, 350M params) run document-scale classification and routing on CPU at 3.7× faster throughput than ModernBERT, scaling efficiently to 8,192-token context.
Summary
Replaces the CPU inference bottleneck for high-volume NLP tasks—intent routing, PII detection, policy checking—letting you deploy classifiers on existing hardware without GPU. Backward-compatible via standard transformers API.

Implementation verdict
Drop-in replacement for BERT-class encoders on CPU-bound workloads. Requires fine-tuning for downstream tasks (included tutorial targets legal documents). Ready now: open-weight models on Hugging Face, live demos run in browser, pip install transformers covers setup. Worth adopting if you own classification/routing latency on CPU.
