URA-LLaMa

Model Details

Model Description

With a strong commitment to enhancing the quality of large language models for the Vietnamese language, a collaborative effort was undertaken by Vietnamese researchers hailing from Ho Chi Minh University of Technology (HCMUT) - Vietnam National University HCMC and Stanford University. Our endeavor involved the meticulous fine-tuning of Meta LLaMa-2 models using Vietnamese articles sourced from Wikipedia and online news websites. In line with our dedication to fostering community progress, we are pleased to offer our models free of charge for research purposes. For those who wish to delve further into our research and its details, we encourage you to explore the comprehensive information provided below.

Uses

This model is primarily designed for text generation. However, as language models, it is versatile and can also function as an encoder for various downstream tasks, akin to other models. For a detailed understanding of its use cases, please refer to the information provided below.

Direct Use

You can use our models to perform various tasks containing

• Question answering (with context)
• Summarization
• Language modelling
• Text classification
• Translation

Downstream Use

This model can serve as an encoder for a wide range of downstream tasks, spanning from pure natural language processing to combinations of natural language processing with computer vision or speech processing.

Out-of-Scope Use

While our models have undergone fine-tuning using extensive Vietnamese datasets, they may not perform optimally in specialized domains necessitating profound domain expertise, such as medicine, politics, chemistry, etc. We kindly request that you refrain from employing our models for political purposes or any endeavors that may cause harm to individuals or compromise the sovereignty and territorial integrity of Vietnam.

Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. In order for the model to work well, you may need perform prompt engineering to create appropriate prompts before inference.

How to Get Started with the Model

Use the code below to get started with the model.

import transformers
from transformers import AutoModelForCausalLM, AutoTokenizer

pipeline_kwargs={
	"temperature": 1.0,
	"max_new_tokens": 250,
	"top_k": 1,
	"repetition_penalty": 1.1
}
  
if __name__ == "__main__":
    # Load model
    model = AutoModelForCausalLM.from_pretrained(
        "ura-hcmut/ura-llama-7b-r64",
        device_map="auto"
    )
    model.config.pretraining_tp = 1
    model.eval()

    # Load tokenizer
    tokenizer = AutoTokenizer.from_pretrained(
        "ura-hcmut/ura-llama-7b-r64", 
        trust_remote_code=True
    )
    tokenizer.pad_token = tokenizer.eos_token
  
    pipeline = transformers.pipeline(
        model=model, 
        tokenizer=tokenizer,
        return_full_text=False,
        task='text-generation',
        **pipeline_kwargs
    )
  
    query_template = "[INST] <<SYS>> Bạn là một trợ lý thông minh. <<SYS>> Hãy trả lời câu hỏi sau.\nCâu hỏi: {query}\nTrả lời:[/INST] "
  
    while True:
        query = input("Query: ")
        if query == "exit":
            break
      
        query = query_template.format(query=query)
        answer = pipeline(query)[0]["generated_text"]
        print(answer)
