gliner2-large-v1 EU AI Act Compliance Profile

Model Description

GLiNER2 extends the original GLiNER architecture to support multi-task information extraction with a schema-driven interface. This large model offers improved performance on challenging extraction tasks while maintaining efficient CPU-based inference.

Key Features:

• Multi-task capability: NER, classification, and structured extraction
• Schema-driven interface with field types and constraints
• Enhanced accuracy for complex and ambiguous extraction scenarios
• CPU-first design for inference without GPU requirements
• 100% local processing with zero external dependencies

Installation

pip install gliner2

Usage

Entity Extraction

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

# 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": Tru
