GLiNER-bi-Encoder: Scalable Zero-Shot Named Entity Recognition

About

GLiNER-bi-Encoder is a novel architecture for Named Entity Recognition (NER) that combines zero-shot flexibility with industrial-scale efficiency. Unlike the original GLiNER, which uses joint encoding, the bi-encoder design decouples text and entity-type encoding, enabling the recognition of thousands of entity types simultaneously with minimal computational overhead.

Key Advantages

Massive Scalability: Handle 1000+ entity types with near-constant inference speed when using pre-computed label embeddings

130× Faster: Up to 130× throughput improvement compared to uni-encoder approaches at 1024 entity types

State-of-the-Art Performance: Achieves 61.5% Micro-F1 on CrossNER benchmark in zero-shot setting

Efficient Caching: Pre-compute and cache entity type embeddings for instant reuse across millions of documents

Architecture

The bi-encoder architecture employs two specialized, independent transformers:

Text Encoder: Processes input sequences using ModernBERT-based encoders (Ettin family)
Label Encoder: Embeds entity type descriptions using specialized sentence transformers (BGE, MiniLM)

This separation removes the context-window bottleneck and enables:

Pre-computation of entity type embeddings
Constant memory usage for text encoding regardless of entity count
Efficient nearest-neighbor search for entity matching

Model Variants

GLiNER-bi-V2 Models:

Model name	Params	Text Encoder	Label Encoder	Avg. CrossNER	Inference Speed (H100, ex/s)	Inference Speed (pre-computed)
gliner-bi-edge-v2.0	60 M	ettin-encoder-32m	all-MiniLM-L6-v2	54.0%	13.64	24.62
gliner-bi-small-v2.0	108 M	ettin-encoder-68m	all-MiniLM-L12-v2	57.2%	7.99	15.22
gliner-bi-base-v2.0	194 M	ettin-encoder-150m	bge-small-en-v1.5	60.3%	5.91	9.51
gliner-bi-large-v2.0	530 M	ettin-encoder-400m	bge-base-en-v1.5	61.5%	2.68	3.60

Recommendation: The base variant (194M) achieves 98% of large model performance while operating 2.6× faster, making it optimal for most production scenarios.

Installation & Usage

Installation

bash

pip install gliner -U
pip install transformers==4.57.0

For flash attention support:

pip install flash-attn triton

Basic Usage

python

from gliner import GLiNER

# Load model
model = GLiNER.from_pretrained("knowledgator/gliner-bi-base-v2.0")

text = """
Cristiano Ronaldo dos Santos Aveiro (Portuguese pronunciation: [kɾiʃˈtjɐnu ʁɔˈnaldu]; born 5 February 1985) is a Portuguese professional footballer who plays as a forward for and captains both Saudi Pro League club Al Nassr and the Portugal national team. Widely regarded as one of the greatest players of all time, Ronaldo has won five Ballon d'Or awards, a record three UEFA Men's Player of the Year Awards, and four European Golden Shoes, the most by a European player.
"""

labels = ["person", "award", "date", "competitions", "teams"]

entities = model.predict_entities(text, labels, threshold=0.3)

for entity in entities:
    print(entity["text"], "=>", entity["label"])

Output:

Cristiano Ronaldo dos Santos Aveiro => person
5 February 1985 => date
Al Nassr => teams
Portugal national team => teams
Ballon d'Or => award
UEFA Men's Player of the Year Awards => award
European Golden Shoes => award

Advanced Usage: Pre-computing Entity Embeddings

For scenarios with large, static entity taxonomies (hundreds to millions of types):

python

from gliner import GLiNER

model = GLiNER.from_pretrained("knowledgator/gliner-bi-base-v2.0")

# Pre-compute embeddings for thousands of entity types
entity_types = ["person", "organization", "location", ...] # Can be thousands
texts = ["Your documents here", ...]

# Encode entity types once
entity_embeddings = model.encode_labels(entity_types, batch_size=8)

# Use pre-computed embeddings for fast inference
outputs = model.batch_predict_with_embeds(texts, entity_embeddings, entity_types)

This approach provides:

130× speedup at 1024 entity types
Constant inference time regardless of entity count
Efficient caching for repeated use

Flash Attention & Extended Context

python

model = GLiNER.from_pretrained(
    "knowledgator/gliner-bi-base-v2.0",
    _attn_implementation='flash_attention_2',
    max_len=2048
).to('cuda:0')
