GLACIER glacier-jurisdiction-router

Distilled legal AI model for the GLACIER pipeline — Gated Legal Analysis, Citation Intelligence, Evidence Routing.

Model Description

This model is distilled from Claude Opus 4.6 (via AWS Bedrock) into a lightweight transformer for fast, local inference. It handles jurisdiction routing (FL, MS, Federal, etc.) as part of the GLACIER 6-stage legal document production pipeline.

• —Base model: distilbert-base-uncased
• —Task: sequence-classification
• —Labels: 8 classes
• —Max length: 512 tokens

Labels

• —fl_state
• —ms_state
• —federal_district
• —federal_circuit
• —scotus
• —bankruptcy
• —administrative
• —unknown

Usage

from glacier_distill.inference import GlacierPipeline

pipeline = GlacierPipeline()
result = pipeline.route_jurisdiction("your legal text here")
print(result)

Or use directly with transformers:

from transformers import pipeline

classifier = pipeline("text-classification", model="glacier-legal/glacier-jurisdiction-router")
result = classifier("your legal text here")

Training

• —Teacher: Claude Opus 4.6 (AWS Bedrock)
• —Method: Knowledge distillation (Hinton et al., 2015) with temperature=4.0, alpha=0.7
• —Data: CourtListener case law + synthetic labeled examples
• —Framework: HuggingFace Transformers + custom DistillationLoss

GLACIER Pipeline

This model is part of the GLACIER pipeline stages:

Stage 1: QUERY    -> jurisdiction-router + document-classifier
Stage 2: RESEARCH -> legal-ner (entity extraction)
Stage 3: WDC #1   -> (full model review)
Stage 4: DRAFT    -> legal-ner + citation-classifier
Stage 5: WDC #2   -> hallucination-detector + citation-classifier
Stage 6: FINAL    -> (human review)

Limitations

• —Distilled models are optimized for US legal text (federal + state)
• —Not a substitute for full model review in GLACIER Stages 3/5
• —Citation hallucination detection is a pre-filter, not a replacement for external verification
• —Jurisdiction coverage: Florida, Mississippi, Federal (primary); other states (limited)
