legal_contract_summarizer_t5

Overview

This model is a T5-based sequence-to-sequence transformer specifically fine-tuned on corporate law datasets. It is designed to ingest lengthy legal contracts (NDAs, Master Service Agreements, TOS) and produce concise, bulleted summaries of key obligations, liabilities, and termination clauses.

Model Architecture

The model follows the Text-to-Text Transfer Transformer (T5) framework:

• Encoder-Decoder: Symmetric 12-layer architecture.
• Pre-training: Originally trained on C4; fine-tuned on a proprietary corpus of 50,000+ legal documents.
• Format: Utilizes prefix-tuning (e.g., "summarize legal: [text]") to trigger specialized legal extraction logic.

Intended Use

• Contract Review: Aiding legal professionals in the rapid audit of large document batches.
• Consumer Protection: Summarizing Terms of Service into plain language for end-users.
• Risk Assessment: Highlighting indemnity clauses and non-compete durations automatically.

Limitations

• Legal Advice: This model is a tool for document analysis and does not constitute legal advice. All outputs should be reviewed by qualified counsel.
• Formatting: Summarization may lose the specific nuance of nested legal definitions if they are not explicitly referenced in the input block.
• Hallucination: Like all LLMs, it may occasionally generate dates or party names not present in the source text if the context is ambiguous.
