⚖️🐉 Indian Legal Qwen 2.5 — 3B (GGUF)

🟡 This is the GGUF-quantized version — for CPU inference via Ollama or llama.cpp. For full-precision inference see the Merged Model · For lightweight adapter loading see the Adapter.

📖 Model Description

Indian Legal Qwen 2.5 — 3B (GGUF) is a quantized, CPU-friendly version of GSMS-B/Indian-Legal-Qwen2.5-3B, a domain-adapted model fine-tuned using QLoRA on a structured question-answer dataset covering all 1,059 sections of India's three landmark 2023 criminal justice reform acts:

Act	Full Name	Replaces	Sections
📕 BNS 2023	Bharatiya Nyaya Sanhita	IPC 1860	358
📗 BNSS 2023	Bharatiya Nagarik Suraksha Sanhita	CrPC 1973	531
📘 BSA 2023	Bharatiya Sakshya Adhiniyam	Indian Evidence Act 1872	170

Trained on 6,354 instruction-format QA pairs — 6 question types per section covering definitions, scenarios, legal elements, exceptions, and consequences — giving it broad, structured coverage of India's reformed criminal law framework. This GGUF build lets you run the model without a GPU, using llama.cpp or Ollama.

🔗 Model Family — Qwen 2.5 3B

Variant	Repo	Best For
🟢 Merged	GSMS-B/Indian-Legal-Qwen2.5-3B	Out-of-the-box inference, Gradio / API deployment
🔵 LoRA Adapter	GSMS-B/Indian-Legal-Qwen2.5-3B-Adapter	Lightweight loading on top of base model
🟡 GGUF (this repo)	`GSMS-B/Indian-Legal-Qwen2.5-3B-GGUF`	CPU inference via Ollama / llama.cpp

🚀 Quick Start

💻 Run with Ollama

ollama run hf.co/GSMS-B/Indian-Legal-Qwen2.5-3B-GGUF

⚙️ Run with llama.cpp

bash

./llama-cli \
  -hf GSMS-B/Indian-Legal-Qwen2.5-3B-GGUF \
  -p "What is a Zero FIR under BNSS 2023?" \
  -n 300 \
  --temp 0.1

🐍 Run with llama-cpp-python

python

from llama_cpp import Llama

llm = Llama.from_pretrained(
    repo_id="GSMS-B/Indian-Legal-Qwen2.5-3B-GGUF",
    filename="*.gguf",
)

SYSTEM = "You are an expert legal assistant specializing in Indian criminal law — BNS, BNSS, and BSA 2023."

response = llm.create_chat_completion(
    messages=[
        {"role": "system", "content": SYSTEM},
        {"role": "user", "content": "What is a Zero FIR under BNSS 2023?"}
    ],
    temperature=0.1,
    max_tokens=300
)

print(response["choices"][0]["message"]["content"])

🎯 Recommended Use Cases

⚠️ Important Note: This model has been domain-adapted on structured QA data and works best as a component in a larger pipeline rather than a standalone answer engine. Direct usage without retrieval context may produce incomplete or imprecise answers on complex legal queries.

✅ Where this model excels

Use Case	💡 How to Use
🔍 RAG Pipeline	Pair with a BM25 or vector retriever over BNS/BNSS/BSA texts; feed retrieved sections as context for grounded, citation-backed answers
🤖 Legal Chatbot Backend	Use as the generation backbone of a legal assistant app with a ChromaDB / FAISS document store
📚 Legal Education Tool	Build interactive Q&A apps for law students and practitioners learning the 2023 criminal justice reforms
🔎 Section Lookup Assistant	Combine with a section index to surface the exact BNS / BNSS / BSA provision relevant to a given situation
💻 Offline / Edge Deployment	Run on consumer CPUs without a GPU — ideal for local apps, kiosks, or low-resource environments
📝 Structured Legal Summarization	Summarize individual sections when the section text is supplied as input context
🏛️ Legal NLP Research	Benchmark Indian criminal law understanding across model families (Qwen vs Llama)
⚖️ Comparative Law Analysis	Highlight differences between old acts (IPC/CrPC/IEA) and their 2023 replacements

❌ Not recommended for

Standalone legal advice without a retrieval component
High-stakes legal decisions without qualified human review
Jurisdictions or acts outside BNS / BNSS / BSA 2023
