GUI-Actor-7B with Qwen2-VL-7B as backbone VLM

This model was introduced in the paper GUI-Actor: Coordinate-Free Visual Grounding for GUI Agents. It is developed based on Qwen2-VL-7B-Instruct , augmented by an attention-based action head and finetuned to perform GUI grounding using the dataset here.

For more details on model design and evaluation, please check: 🏠 Project Page | 💻 Github Repo | 📑 Paper.
