Uses

Direct Use

The model can be directly used for generating medical responses in Thai. It has been optimized for:

• Medical question-answering
• Providing clinical information
• Health-related dialogue generation

Downstream Use

This model can be used as a foundational model for medical assistance systems, chatbots, and applications related to healthcare, specifically in the Thai language.

Out-of-Scope Use

• This model should not be used for real-time diagnosis or emergency medical scenarios.
• Avoid using it for critical clinical decisions without human oversight, as the model is not intended to replace professional medical advice.

Bias, Risks, and Limitations

Bias

• The model might reflect biases present in the dataset, particularly when addressing underrepresented medical conditions or topics.

Risks

• Responses may contain inaccuracies due to the inherent limitations of the model and the dataset used for fine-tuning.
• This model should not be used as the sole source of medical advice.

Limitations

• Limited to the medical domain.
• The model is sensitive to prompts and may generate off-topic responses for non-medical queries.

How to Get Started with the Model

Here’s how to load and use the model for generating medical responses in Thai:

Using Google Colab Pro or Pro+ for fine-tuning and inference.

1. Install the Required Packages

First, ensure you have installed the required libraries by running:

! pip install --upgrade torch transformers accelerate bitsandbytes --upgrade

2. Load the Model and Tokenizer

You can load the model and tokenizer directly from Hugging Face using the following code:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig

Define the model path

model_path = 'amornpan/openthaigpt1.5-14b-MedChatModelV1'

Load the tokenizer and model

tokenizer = AutoTokenizer.from_pretrained(model_path)
tokenizer.pad_token = tokenizer.eos_token

3. Prepare Your Input (Custom Prompt)

Create a custom medical prompt that you want the model to respond to:

custom_prompt = "โปรดอธิบายลักษณะช่องปากที่เป็นมะเร็งในระยะเริ่มต้น"
PROMPT = f'[INST] <You are a question answering assistant. Answer the question as truthfully and helpfully as possible. คุณคือผู้ช่วยตอบคำถาม จงตอบคำถามอย่างถูกต้องและมีประโยชน์ที่สุด<>{custom_prompt}[/INST]'

# Tokenize the input prompt
inputs = tokenizer(PROMPT, return_tensors="pt", padding=True, truncation=True)

4. Configure the Model for Efficient Loading (4-bit Quantization)

The model uses 4-bit precision for efficient inference. Here’s how to set up the configuration:

bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.float16
)

5. Load the Model with Quantization Support

Now, load the model with the 4-bit quantization settings:

model = AutoModelForCausalLM.from_pretrained(
    model_path,
    quantization_config=bnb_config,
    trust_remote_code=True
)

6. Move the Model and Inputs to the GPU (prefer GPU)

For faster inference, move the model and input tensors to a GPU, if available:

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.to(device)
inputs = {k: v.to(device) for k, v in inputs.items()}

7. Generate a Response from the Model

Now, generate the medical response by running the model:

outputs = model.generate(**inputs, max_new_tokens=256, do_sample=True)

8. Decode the Generated Text

Finally, decode and print the response from the model:

generated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(generated_text)

9. Output

[INST] <You are a question answering assistant. Answer the question as truthfully and helpfully as possible.
คุณคือผู้ช่วยตอบคำถาม จงตอบคำถามอย่างถูกต้องและมีประโยชน์ที่สุด<>
โปรดอธิบายลักษณะช่องปากที่เป็นมะเร็งในระยะเริ่มต้น[/INST]

สำหรับมะเร็งช่องปากในระยะแรกอาจรวมถึงอาการหรือลักษณะดังต่อไปนี้:
1. แผลบนช่องปากหรือกระพูดนิ่มที่อยู่กับที่และไม่หายไปแม้จะผ่านการรักษาด้วยตนเอง
2. บวมที่อยู่กับที่ที่ข้างใดข้างหนึ่งของริมฝีปาก
3. แผลเปื่อยหรือพังผืดที่เกิดขึ้นที่กระพูดหรือฟันที่ไม่หาย
4. ความเปลี่ยนแปลงของผิว pigment ในช่องปาก เช่น สีของกระพืดหรือริมฝีปากที่เปลี่ยนเป็นสีขาวหรือขาว
5. ปัญหาในการพูดหรือกินอาหาร
6. ขดลวดที่ด้านข้างหรือใต้คอที่เจริญเติบโต
7. อาการเจ็บจี๊ด
