Model Card for dhee-chat-mistral-ta

A fine-tuned Tamil conversational model based on mistralai/Mistral-7B-v0.3 , optimized for Tamil language understanding and generation.

Model Details

• Base Model: Mistral 7B v0.3
• Fine-tuning Method: LoRA (Low-Rank Adaptation)
• Dataset: ai4bharat/indic-align
• Language: Tamil
• Model ID: dheeyantra/dhee-chat-mistral-ta

Intended Uses & Limitations

This model is intended for use in Tamil conversational applications, such as chatbots and virtual assistants. As it is fine-tuned on the ai4bharat/indic-align dataset, its knowledge and conversational style are primarily shaped by this data.

Limitations:

• The model's responses are based on the patterns and information present in the training data. It may generate incorrect or biased information.
• Performance may vary depending on the complexity and nuance of the input.
• The model is primarily focused on Tamil and may not perform well in other languages or code-mixed scenarios unless explicitly trained for them.

How to Get Started with Hugging Face Transformers

You can use the following Python code to load and run inference with the dheeyantra/dhee-chat-mistral-ta model:

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_path = "dheeyantra/dhee-chat-mistral-ta"

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path)

# Move model to GPU if available
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.to(device)

# Prepare chat messages
messages = [
    {"role": "User", "content": "எத்தனை வேதங்கள் உள்ளன?"},
    {"role": "Dhee", "content": "நான்கு வேதங்கள் உள்ளன: ரிக்வேதம், யஜுர்வேதம், சாமவேதம் மற்றும் அதர்வவேதம்."},
    {"role": "User", "content": "ரிக் வேதத்தைப் பற்றி மேலும் சொல்லுங்கள்?"}
]

# Apply chat template to get prompt
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)

# Tokenize prompt
inputs = tokenizer(prompt, return_tensors="pt").to(device)

# Generate output
with torch.no_grad():
    output_ids = model.generate(
        **inputs,
        max_new_tokens=64,
        do_sample=True,
        temperature=0.7,
        top_p=0.95,
        pad_token_id=tokenizer.eos_token_id
    )

# Decode generated text
generated_text = tokenizer.decode(output_ids[0][inputs['input_ids'].shape[-1]:], skip_special_tokens=True)
results = [{"generated_text": generated_text}]

print("Generated text:")
print(results[0]['generated_text'])
