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:

python

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'])
