+# Gemma-3-4B Fine-tuned for Bean Disease Classification
+This model is a fine-tuned version of [google/gemma-3-4b-it](https://huggingface.co/google/gemma-3-4b-it) for classifying bean plant diseases.
+## Model Description
+- **Base Model:** Gemma-3-4B-IT (Vision)
+- **Fine-tuning Method:** LoRA (r=8, alpha=16)
+- **Dataset:** [beans](https://huggingface.co/datasets/beans) (100 samples)
+- **Task:** Image captioning / disease classification
+- **Final Validation Loss:** 0.001 (excellent!)
+## Classes
+1. Healthy bean plant
+2. Angular leaf spot disease
+3. Bean rust disease
+## Usage
+```python
+from transformers import AutoProcessor, Gemma3ForConditionalGeneration
+from peft import PeftModel
+from PIL import Image
+import torch
+# Load base model
+base_model = Gemma3ForConditionalGeneration.from_pretrained(
+    "google/gemma-3-4b-it",
+    torch_dtype=torch.bfloat16,
+    device_map="auto"
+)
+# Load LoRA adapter
+model = PeftModel.from_pretrained(base_model, "Khytron/gemma3-4b-bean-captioning")
+processor = AutoProcessor.from_pretrained("Khytron/gemma3-4b-bean-captioning")
+# Prepare input
+image = Image.open("bean_plant.jpg")
+messages = [
+    {
+        "role": "user",
+        "content": [
+            {"type": "image"},
+            {"type": "text", "text": "Describe this plant image."}
+        ]
+    }
+]
+text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+inputs = processor(text=text, images=image, return_tensors="pt").to(model.device)
+# Generate
+outputs = model.generate(**inputs, max_new_tokens=50, do_sample=False)
+response = processor.decode(outputs[0], skip_special_tokens=True)
+print(response)
+```
 ## Training Details
+- **Epochs:** 10
+- **Batch Size:** 1 (effective: 4 with gradient accumulation)
+- **Learning Rate:** 5e-5
+- **Precision:** FP16
+- **Hardware:** NVIDIA T4 GPU
+- **Training Time:** ~25 minutes
+- **Max Sequence Length:** 512 tokens
+## Performance
+- **Final Training Loss:** 0.69
+- **Final Validation Loss:** 0.001
+- **Accuracy:** Very high (based on validation loss)
+## Limitations
+- Trained on 100 images for demonstration purposes
+- Best suited for the 3 specific bean disease types in the training data
+- May not generalize to other bean varieties or diseases
+- Should be validated on real-world data before production use
