GLiNER2: Unified Schema-Based Information Extraction and Text Classification

Extract entities, classify text, parse structured data, and extract relations—all in one efficient model.

GLiNER2 unifies Named Entity Recognition, Text Classification, Structured Data Extraction, and Relation Extraction into a single 205M parameter model. It provides efficient CPU-based inference without requiring complex pipelines or external API dependencies.

Fine-tune via Fastino. Join discussions on Discord and Reddit.

✨ Why GLiNER2?

🎯 One Model, Four Tasks: Entities, classification, structured data, and relations in a single forward pass
💻 CPU First: Lightning-fast inference on standard hardware—no GPU required
🛡️ Privacy: 100% local processing, zero external dependencies

Installation

pip install gliner2

Usage

Entity Extraction

python

from gliner2 import GLiNER2

# Load the model
extractor = GLiNER2.from_pretrained("fastino/gliner2-large-v1")

# Extract entities with descriptions for higher precision
text = "Patient received 400mg ibuprofen for severe headache at 2 PM."
result = extractor.extract_entities(
    text,
    {
        "medication": "Names of drugs, medications, or pharmaceutical substances",
        "dosage": "Specific amounts like '400mg', '2 tablets', or '5ml'",
        "symptom": "Medical symptoms, conditions, or patient complaints",
        "time": "Time references like '2 PM', 'morning', or 'after lunch'"
    }
)

print(result)
# Output: {'entities': {'medication': ['ibuprofen'], 'dosage': ['400mg'], 'symptom': ['severe headache'], 'time': ['2 PM']}}

Text Classification

python

# Single-label classification
result = extractor.classify_text(
    "This laptop has amazing performance but terrible battery life!",
    {"sentiment": ["positive", "negative", "neutral"]}
)
print(result)
# Output: {'sentiment': 'negative'}

# Multi-label classification
result = extractor.classify_text(
    "Great camera quality, decent performance, but poor battery life.",
    {
        "aspects": {
            "labels": ["camera", "performance", "battery", "display", "price"],
            "multi_label": True,
            "cls_threshold": 0.4
        }
    }
)
print(result)
# Output: {'aspects': ['camera', 'performance', 'battery']}

Structured Data Extraction

python

# Financial document processing
text = """
Transaction Report: Goldman Sachs processed a $2.5M equity trade for Tesla Inc. 
on March 15, 2024. Commission: $1,250. Status: Completed.
"""

result = extractor.extract_json(
    text,
    {
        "transaction": [
            "broker::str::Financial institution or brokerage firm",
            "amount::str::Transaction amount with currency",
            "security::str::Stock, bond, or financial instrument",
            "date::str::Transaction date",
            "commission::str::Fees or commission charged",
            "status::str::Transaction status",
            "type::[equity|bond|option|future|forex]::str::Type of financial instrument"
        ]
    }
)

print(result)
# Output: {
#     'transaction': [{
#         'broker': 'Goldman Sachs',
#         'amount': '$2.5M',
#         'security': 'Tesla Inc.',
#         'date': 'March 15, 2024',
#         'commission': '$1,250',
#         'status': 'Completed',
#         'type': 'equity'
#     }]
# }

Multi-Task Schema Composition

python

# Comprehensive legal contract analysis
contract_text = """
Service Agreement between TechCorp LLC and DataSystems Inc., effective January 1, 2024.
Monthly fee: $15,000. Contract term: 24 months with automatic renewal.
Termination clause: 30-day written notice required.
"""

schema = (extractor.create_schema()
    .entities(["company", "date", "duration", "fee"])
    .classification("contract_type", ["service", "employment", "nda", "partnership"])
    .structure("contract_terms")
        .field("parties", dtype="list")
        .field("effective_date", dtype="str")
        .field("monthly_fee", dtype="str")
        .field("term_length", dtype="str")
        .field("renewal", dtype="str", choices=["automatic", "manual", "none"])
        .field("termination_notice", dtype="str")
)

results = extractor.extract(contract_text, schema)

print(results)
# Output: {
#     'entities': {
#         'company': ['TechCorp LLC', 'DataSystems Inc.'],
#         'date': ['January 1, 2024'],
#         'duration': ['24 months'],
#         'fee': ['$15,000']
#     },
#     'contract_type': 'service',
#     'contract_terms': [{
#         'parties': ['TechCorp LLC', 'DataSystems Inc.'],
#         'effective_date': 'January 1, 2024',
#         'monthly_fee': '$15,000',
#         'term_length': '24 months',
#         'renewal': 'automatic',
#         'termination_notice': '30-day written notice'
#     }]
# }
