Model Card for LawLumin-1.7B
Model Description
JurisQwen-1.7B-CoT is a fine-tuned version of Qwen3-1.7B, specialized for legal reasoning and analytical thinking using structured Chain-of-Thought (CoT) methodology. This model was trained on the moremilk/CoT_Legal_Issues_And_Laws — a curated collection of simplified legal reasoning tasks designed to help AI systems learn how to identify legal issues, apply rules, and derive logical conclusions through transparent step-by-step reasoning.
📘 Intended Use
Primary Use Cases:
- Research on automated legal reasoning and structured CoT prompting.
- Educational tools to teach the logic of legal analysis in simplified contexts.
- Development and benchmarking of explainable reasoning systems in law and ethics.
Examples of What It Can Do:
- Identify potential legal issues in a hypothetical scenario.
- Articulate simplified legal principles or rules.
- Apply those rules to a set of facts and reason toward a logical conclusion.
- Provide interpretable explanations of its reasoning process.
🚫 Out-of-Scope
This model must not be used for:
- Providing legal advice or professional representation.
- Deciding or predicting outcomes in real-world legal cases.
- Interpreting actual statutes, case law, or jurisdiction-specific rules.
- Simulating legal practice, strategy, or procedural law.
The model is intended strictly for research and educational purposes within a simplified, illustrative legal reasoning framework.
Bias, Risks, and Limitations
- Simplified Legal Scope: Only reflects general reasoning patterns — not actual laws or jurisdictions.
- No Factual Authority: Cannot verify legal facts, interpret statutes, or provide reliable advice.
- Ethical Use: Always ensure human oversight in any downstream application.
How to Get Started with the Model
Use the code below to get started with the model.

Dataset
Dataset: moremilk/CoT_Legal_Issues_And_Laws Scope:
- Core Legal Reasoning Tasks: Identifying issues, stating relevant simplified rules, applying those rules to facts, and deriving conclusions.
- Illustrative Scenarios: Demonstrating legal logic with examples from basic tort, contract, or property situations.
- Emphasis on CoT: Step-by-step reasoning transparency for interpretability and explainability research.
- Foundational Focus: Designed to train models in logical, structured legal reasoning — not domain-specific law practice.
