# World Model LoRA Adapter

LoRA adapter fine-tuned on [ageppert/world-model-transitions](https://huggingface.co/datasets/ageppert/world-model-transitions)
for predicting GUI state transitions in desktop computer-use tasks.

## Base Model
[xlangai/OpenCUA-7B](https://huggingface.co/xlangai/OpenCUA-7B)

## Usage
```python
from peft import PeftModel
from transformers import AutoModelForVision2Seq, AutoProcessor

base_model = AutoModelForVision2Seq.from_pretrained("xlangai/OpenCUA-7B", trust_remote_code=True)
model = PeftModel.from_pretrained(base_model, "ageppert/world-model-7b-lora")
processor = AutoProcessor.from_pretrained("ageppert/world-model-7b-lora")
```

## Training
