 This model was introduced in the paper [**GUI-Actor: Coordinate-Free Visual Grounding for GUI Agents**](https://aka.ms/GUI-Actor).
 It is developed based on [Qwen2-VL-7B-Instruct ](https://huggingface.co/Qwen/Qwen2-VL-7B-Instruct), augmented by an attention-based action head and finetuned to perform GUI grounding using the dataset [here (coming soon)]().
