via “structured data extraction and information retrieval from unstructured text”

Compact 3B model balancing capability with edge deployment.

Unique: 128K context enables extraction from entire documents without chunking, combined with instruction-tuning for flexible output formatting — most extraction systems require specialized NER models or RAG with limited context
