It’s fascinating to see how multimodal LLMs are being applied to UI understanding—definitely a challenging area that highlights the current limitations and potential of these models. The interactive app looks like a great way to visualize the model's performance in real-time, and it’s exciting to see tools like GPT Engineer being used to build such innovative demos. This kind of hands-on experimentation is essential for advancing the field and discovering new ways to improve model accuracy with fine-tuning. Looking forward to seeing where this goes!
