## Introduction

GUI-Owl-1.5 is a native multi-platform GUI agent model family featuring instruct and thinking variants. It supports a wide range of platforms, including desktop, mobile, and browser environments, to enable cloud-edge collaboration and real-time interaction. The model unifies perception, grounding, reasoning, planning, and action execution within a single policy network.

Key features include:
- **Hybrid Data Flywheel:** A data pipeline for UI understanding and trajectory generation based on simulated and cloud-based sandbox environments.
- **Unified Enhancement of Agent Capabilities:** A unified thought-synthesis pipeline to enhance reasoning, memory, and Tool/MCP (Model Context Protocol) usage.
- **Multi-platform Environment RL Scaling:** Uses a new environment RL algorithm, MRPO, to address challenges in multi-platform interaction and long-horizon task training.

## Benchmarks

GUI-Owl-1.5 achieves state-of-the-art results on more than 20 GUI benchmarks:
- **GUI Automation:** OSWorld (56.5), AndroidWorld (71.6), and WebArena (48.4).
- **Grounding:** ScreenSpotPro (80.3).
- **Tool-calling:** OSWorld-MCP (47.6) and MobileWorld (46.8).
- **Memory & Knowledge:** GUI-Knowledge Bench (75.5).
