Overview
DistilBERT NER is Elastic's production NER model fine-tuned on CoNLL-2003, delivering 40% faster inference than BERT-base-NER at 90% of the F1 score -- the performance-efficiency tradeoff that makes it the preferred choice for high-throughput real-time NER pipelines. With 1M+ monthly downloads from the Elasticsearch and Elastic NLP community, it is the standard for streaming document entity extraction where latency matters: news wire processing, real-time contract screening, live customer communication monitoring, and high-volume compliance event detection. At ~260MB it loads faster, uses less memory, and serves more concurrent requests on ml.m5.xlarge than the full BERT variant.
Highlights
- 40% faster inference than BERT-base-NER -- optimized for high-throughput real-time pipelines
- 1M+ monthly downloads from Elasticsearch and Elastic NLP production deployments
- 260MB footprint enables higher concurrency per ml.m5.xlarge instance
