## Usage

### Installation

```bash
pip install transformers pillow torch
```

### Basic Image Understanding

```python
from transformers import AutoProcessor, AutoModelForVision2Seq
from PIL import Image
import requests

model_name = "your-username/mineral-nano-1"
processor = AutoProcessor.from_pretrained(model_name)
model = AutoModelForVision2Seq.from_pretrained(model_name)

# Load an image
url = "https://example.com/image.jpg"
image = Image.open(requests.get(url, stream=True).raw)

# Prepare inputs
prompt = "<image>What is in this image?"
inputs = processor(text=prompt, images=image, return_tensors="pt")

# Generate response
outputs = model.generate(**inputs, max_new_tokens=100)
response = processor.decode(outputs[0], skip_special_tokens=True)
print(response)
```

### Multiple Images

```python
from PIL import Image

images = [
    Image.open("image1.jpg"),
    Image.open("image2.jpg")
]

prompt = "<image>Describe the first image. <image>Now describe the second image."
inputs = processor(text=prompt, images=images, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=200)
print(processor.decode(outputs[0], skip_special_tokens=True))
```

### Chat with Images

```python
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image"},
            {"type": "text", "text": "What objects are in this image?"}
        ]
    }
]

# Apply chat template
text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = processor(text=text, images=image, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=150, temperature=0.7)
print(processor.decode(outputs[0], skip_special_tokens=True))
```

### Local Images

```python
from PIL import Image

# Load local image
image = Image.open("path/to/your/image.jpg")

prompt = "<image>Describe what you see in detail."
inputs = processor(text=prompt, images=image, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=256)
print(processor.decode(outputs[0], skip_special_tokens=True))
```

## Training Details

- **Framework:** PyTorch with Transformers
- **Training Data:** Text + Image pairs
- **Training Duration:** [Specify training time]
- **Hardware:** [Specify GPUs used]
- **Vision Encoder:** Pretrained ViT encoder fine-tuned with language model

## Capabilities

✅ Image description and captioning
✅ Visual question answering
✅ Object detection and recognition
✅ Scene understanding
✅ Multi-image reasoning
✅ OCR and text extraction from images

## Limitations

- Limited to 224x224 resolution images
- Context window of 2048 tokens including image tokens
- May struggle with fine-grained details
- Best for general image understanding tasks
- Compact size means reduced capabilities compared to larger VLMs
- Limited multilingual vision capabilities

## Intended Use

This model is designed for:
- Educational purposes and learning VLM architectures
- Prototyping multimodal applications
- Low-resource deployment scenarios
- Fast inference with vision capabilities
- Mobile and edge device applications
- Personal projects requiring image understanding

## Image Preprocessing

Images are automatically:
- Resized to 224x224
- Normalized with CLIP-style statistics
- Converted to RGB
- Split into 16x16 patches (196 total patches)

## Performance Tips

- Use square images when possible for best results
- Ensure images are clear and well-lit
- Keep prompts concise and specific
- Use batch processing for multiple images
- Enable `use_cache=True` for faster generation
