Batch Token Classification With Configurable Output Formats

token-classification model by undefined. 3,07,609 downloads.

Unique: Supports multiple output formats (BIO, BIOES, logits, confidence scores) from single inference pass without re-running model, reducing computational overhead for downstream tasks requiring different label representations

vs others: More flexible output options than spaCy's token classification (which outputs only single label per token); more efficient than running separate inference passes for different output formats

Unique: Supports custom hypothesis template formatting at batch inference time, allowing users to inject domain-specific phrasing without model retraining. Batching is transparent to the user but critical for production throughput; templates are formatted per-label and cached within a batch to avoid redundant tokenization.

vs others: More efficient than single-sample inference loops (10-50x faster on GPU) and more flexible than fixed-template classifiers because templates are user-configurable, enabling domain adaptation through prompt engineering rather than fine-tuning.

token-classification model by undefined. 2,90,595 downloads.

Unique: Supports configurable output formats (BIO, BIOES, flat labels, logits) and automatic token-to-character alignment via SafeTensors-backed tokenizer, enabling seamless integration with downstream NER/chunking pipelines without custom glue code.

vs others: More flexible output formatting than spaCy's fixed Doc/Token objects; faster batch processing than sequential inference due to GPU parallelism; more accurate token-to-character alignment than regex-based post-processing.
