Model Description

The Indian Legal Assistant is a text generation model specifically trained to understand and generate text related to Indian law. It can be used for tasks such as:

• Legal question answering
• Case summarization
• Legal document analysis
• Statute interpretation

Model Details

Installation

To use this model, you'll need to install the required libraries:

pip install transformers torch
# For GGUF support
pip install llama-cpp-python

Usage

There are several ways to use the Indian Legal Assistant model:

1. Using Hugging Face Pipeline

from transformers import pipeline

pipe = pipeline("text-generation", model="varma007ut/Indian_Legal_Assitant")

prompt = "Summarize the key points of the Indian Contract Act, 1872:"
result = pipe(prompt, max_length=200)
print(result[0]['generated_text'])

2. Using Hugging Face Transformers directly

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("varma007ut/Indian_Legal_Assitant")
model = AutoModelForCausalLM.from_pretrained("varma007ut/Indian_Legal_Assitant")

prompt = "What are the fundamental rights in the Indian Constitution?"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=200)
print(tokenizer.decode(outputs[0]))

3. Using GGUF format with llama-cpp-python

from llama_cpp import Llama

llm = Llama.from_pretrained(
    repo_id="varma007ut/Indian_Legal_Assitant",
    filename="ggml-model-q4_0.gguf",  # Replace with the actual GGUF filename if different
)

response = llm.create_chat_completion(
    messages = [
        {
            "role": "user",
            "content": "Explain the concept of judicial review in India."
        }
    ]
)

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

4. Using Inference Endpoints

This model supports Hugging Face Inference Endpoints. You can deploy the model and use it via API calls. Refer to the Hugging Face documentation for more information on setting up and using Inference Endpoints.

Evaluation

To evaluate the model's performance:

1. Prepare a test set of Indian legal queries or tasks.
2. Use standard NLP evaluation metrics such as perplexity, BLEU score, or task-specific metrics.

Example using BLEU score:

from datasets import load_metric

bleu = load_metric("bleu")
predictions = model.generate(encoded_input)
results = bleu.compute(predictions=predictions, references=references)
