## Usage
To use the model with the Hugging Face `transformers` library:

```python
from transformers import AutoTokenizer, AutoModel

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("nectec/Pathumma-llm-vision-1.0.0")
model = AutoModel.from_pretrained("nectec/Pathumma-llm-vision-1.0.0")
N = 5

processor = AutoProcessor.from_pretrained(
    "nectec/Pathumma-llm-vision-1.0.0",
    do_image_splitting=False,
    # size={"longest_edge": N*364},            # Optional
    # size={"height": N*364, "width": N*364},  # Optional
)

model = Idefics3ForConditionalGeneration.from_pretrained(
        "nectec/Pathumma-llm-vision-1.0.0",
        torch_dtype=torch.float16,
        device_map=DEVICE
    )

print(processor.image_processor.size)

url_path = None
local_path = "./path/picture.jpg" if not url_path else io.BytesIO(requests.get(url_path).content)
image = Image.open(local_path)

question = "รายละเอียดของรูปภาพนี้"
messages = [
    {
        "role": "user",
        "content": [
            {"type": "text", "text": "You are a helpful assistant."},
            {"type": "image"},
            {"type": "text", "text": question}
        ]
    }
]

text = processor.apply_chat_template(
    messages,
    add_generation_prompt=True,
)

encoding = processor(
    images=image,
    text=text.strip(),
    # padding='max_length',
    # truncation=True,
    # max_length=,
    return_tensors="pt"
)

encoding = {k: v.to(DEVICE) for k, v in encoding.items()}

# Example: Run inference on text input
start_time = time.time()
model.eval()
with torch.inference_mode():
    # Generate
    generated_ids = model.generate(
        **inputs, 
        max_new_tokens=128, 
        # temperature=.5, 
        # repetition_penalty=1.,
        # # top_k=1.,
        # top_p=1,
    )
    generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0]
end_time = time.time()

## Get letency_time...
latency_time = end_time - start_time

answer_prompt = generated_text.split('Assistant:')[1].strip()

# Output processing (depends on task requirements)
print(answer_prompt)
print(latency_time)
```

## Limitations and Biases
- The model may exhibit biases due to the training data, which might not be fully representative of all contexts.
- Performance may degrade on unfamiliar images or non-standard question formats.

## Ethical Considerations
- The model should not be used to generate misleading information or in ways that violate privacy.
- Consider fairness and minimize bias when using the model for language and image processing tasks.
