Tamil LLaMA 7B Instruct v0.2

Welcome to the inaugural release of the Tamil LLaMA 7B instruct model – an important step in advancing LLMs for the Tamil language. This model is ready for immediate inference and is also primed for further fine-tuning to cater to your specific NLP tasks.

To dive deep into the development and capabilities of this model, please read the research paper and the introductory blog post (WIP) that outlines our journey and the model's potential impact.

Note: This model is based on the Tamil LLaMA series of models. The GitHub repository remains the same - https://github.com/abhinand5/tamil-llama. The base models and the updated code for Tamil LLaMA v0.2 (which this work is based on) will be released soon.

If you appreciate this work and would like to support its continued development, consider buying me a coffee. Your support is invaluable and greatly appreciated.

Model description

The Tamil LLaMA models have been enhanced and tailored specifically with an extensive Tamil vocabulary of ~16,000 tokens, building upon the foundation set by the original LLaMA-2.

  • Model type: A 7B parameter GPT-like model finetuned on ~500,000 samples consisting of an equal proportion of English and Tamil samples. (Dataset will be released soon)
  • Language(s): Bilingual. English and Tamil.
  • License: GNU General Public License v3.0
  • Finetuned from model: To be released soon
  • Training Precision: bfloat16
  • Code: GitHub (To be updated soon)

Prompt Template: ChatML

<|im_start|>system
{system_message}<|im_end|>
<|im_start|>user
{prompt}<|im_end|>
<|im_start|>assistant

Benchmark Results

Benchmarking was done using LLM-Autoeval on an RTX 3090 on runpod.

Note: Please note that discrepancies have been observed between the Open LLM Leaderboard scores and those obtained from local runs using the LM Eval Harness with identical configurations. The results mentioned here are based on our own benchmarking. To replicate these findings, you can utilize the LLM-Autoeval or use lm-evaluation-harness locally with the configurations described in Open LLM Leaderboard's About page.

Example Usage

from transformers import LlamaForCausalLM, AutoTokenizer, pipeline

model = LlamaForCausalLM.from_pretrained(
    "abhinand/tamil-llama-instruct-v0.2",
    #load_in_8bit=True, # Set this depending on the GPU you have
    torch_dtype=torch.bfloat16,
    device_map={"": 0}, # Set this depending on the number of GPUs you have
    local_files_only=False # Optional
)
model.eval()

tokenizer = AutoTokenizer.from_pretrained("abhinand/tamil-llama-instruct-v0.2")

inf_pipeline = pipeline("conversational", model=model, tokenizer=tokenizer)


def format_instruction(system_prompt, question, return_dict=False):
    if system_prompt is None:
        messages = [
            {'content': question, 'role': 'user'},
        ]
    else:
        messages = [
            {'content': system_prompt, 'role': 'system'},
            {'content': question, 'role': 'user'},
        ]

    if return_dict:
        return messages

    prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)

    return prompt


# Set the generation configuration according to your needs
temperature = 0.6
repetition_penalty = 1.1
max_new_tokens = 256

SYSTEM_PROMPT = "You are an AI assistant who follows instructions extremely well. Do your best your best to help."
INPUT = "Can you explain the significance of Tamil festival Pongal?"

instruction = format_instruction(
    system_prompt=SYSTEM_PROMPT,
    question=INPUT,
    return_dict=True,
)

output = inf_pipeline(
    instruction,
    temperature=temperature,
    max_new_tokens=max_new_tokens,
    repetition_penalty=repetition_penalty
)
print(output)

Example Output:

Conversation id: d57cdf33-01ff-4328-8efe-5c4fefdd6e77
system: You are an AI assistant who follows instructions extremely well. Do your best your best to help.
user: Can you explain the significance of Tamil festival Pongal?
assistant: Pongal is a significant harvest festival celebrated in Tamil Nadu and other parts of southern India. It marks the end of the rainy season and beginning of the agricultural year. The festival primarily revolves around giving gratitude to nature, particularly the Sun God Surya for his bountiful gifts like agriculture and health. People offer prayers to cattle, which play a significant role in agriculture, as well as their families for their continued support during the harvest season. The festival is marked by various colorful events, including preparing traditional Pongal dishes like rice cooked with milk, sugarcane, and banana, followed by exchanging gifts and celebrating among family members and friends. It also serves as a time for unity and strengthens the bond between people in their communities.

Usage Note

It's important to note that the models have not undergone detoxification/censorship. Therefore, while they possess impressive linguistic capabilities, there is a possibility for them to generate content that could be deemed harmful or offensive. We urge users to exercise discretion and supervise the model's outputs closely, especially in public or sensitive applications.
