Qwen3-14B Fine-tuned for Indian Legal Domain (POCSO Investigation Assistant)

Model Description

This is a LoRA fine-tuned version of Qwen/Qwen3-14B specifically trained for Indian legal domain tasks, with a focus on POCSO (Protection of Children from Sexual Offences) Act cases.

Model Details

Training Data

The model was fine-tuned on Indian legal case examples including:

• —POCSO Act cases and sections
• —IPC (Indian Penal Code) provisions
• —BNS (Bharatiya Nyaya Sanhita) 2023 sections
• —CrPC/BNSS procedural guidelines
• —Real anonymized complaint documents in English and Telugu

Capabilities

1. SUGGEST_SECTIONS

Suggests applicable legal sections based on complaint text.

2. GENERATE_SUMMARY

Extracts key details (victim, accused, incident) from complaints.

3. IDENTIFY_EVIDENCE

Recommends evidence collection priorities.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen3-14B",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3-14B")

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "vivekvar/qwen3-14b-pocso-legal-assistant")

# Generate
prompt = """Task: Suggest legal sections for this complaint.

Complaint: A 15-year-old girl was harassed by her neighbor.

Output JSON:"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.1)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Evaluation Results

Comparison with GPT + RAG

Limitations

1. 1.May apply wrong law (BNS vs IPC) for cases before July 2024
2. 2.May miss mandatory POCSO sections in edge cases
3. 3.Evidence recommendations less detailed than RAG systems
4. 4.Optimized for English and Telugu
