MixSUra

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 various models using Vietnamese articles sourced from Wikipedia and other sources (if neccessary). 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

Direct Use

You can use our models to perform various tasks containing

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

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.

Bias, Risks, and Limitations

Unless required by applicable law, the MixSUra materials and any output and results therefrom are provided on an "as is" basis, without warranties of any kind, either express or implied, including, without limitation, any warranties of title, non-infringement, merchantability, or fitness for a particular purpose. you are solely responsible for determining the appropriateness of using or redistributing the MixSUra materials and assume any risks associated with your use of the MixSUra materials and any output and results.

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

If you intend to use Ollama, please check this repo. Use the code below to get started with the model.

    "max_new_tokens": 8192,
    "top_k": 0.95,
    "top_p": 50

}
  
if __name__ == "__main__":
    # Load model
    model = AutoModelForCausalLM.from_pretrained(
        "ura-hcmut/MixSUra",
        device_map="auto"
    )
    model.eval()

    # Load tokenizer
    tokenizer = AutoTokenizer.from_pretrained(
        "ura-hcmut/MixSUra",
        trust_remote_code=True
    )
  
    pipeline = transformers.pipeline(
        model=model, 
        tokenizer=tokenizer,
        return_full_text=False,
        task='text-generation',
        **pipeline_kwargs
    )
  
    query_template = "<s> [INST] BαΊ‘n lΓ  mα»™t trợ lΓ½ thΓ΄ng minh. HΓ£y thα»±c hiện cΓ‘c yΓͺu cαΊ§u hoαΊ·c trαΊ£ lời cΓ’u hỏi tα»« người dΓΉng bαΊ±ng tiαΊΏng Việt.\n {query}[/INST] "
  
    while True:
        query = input("Query: ")
        if query == "exit":
            break
      
        query = query_template.format(query=query)
        answer = pipeline(query)[0]["generated_text"]
        print(answer)
