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:

python

pip install torch transformers bitsandbytes

[!pip install bitsandbytes --upgrade]

[!pip install --upgrade transformers huggingface_hub]

2. Load the Model and Tokenizer

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

python

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig

Define the model path

model_path = 'amornpan/openthaigpt-MedChatModelv11'

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:

python

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:

python

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:

python

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:

python

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:

python

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

9. Output

python

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

- มีเนื้องอกสีขาวหรือสีเทามีขนาดเล็กอยู่บริเวณเยื่อบุช่องปาก
- มีแผลในช่องปากที่ไม่หายภายในสองสัปดาห์
- มีแผลบริเวณจมูกหรือคอที่มีมานานแต่ไม่หาย
- มีเนื้อ hardness หรือการเปลี่ยนแปลงทางโครงสร้างในบริเวณเยื่อบุของช่องปาก
- มีความผิดปกติในรูปร่าง ขนาด และสีของฟัน
- มีการเปลี่ยนแปลงในการบิดงอของลิ้นหรือมัดกล้ามเนื้อที่รับผิดชอบการบิดงอ

สิ่งจำเป็นคือให้พบแพทย์ผู้เชี่ยวชาญโดยเร็วที่สุดหากมีอาการที่
