CAGUI: Chinese Android GUI Benchmark

A real-world Chinese Android GUI benchmark designed to evaluate GUI agent models on two complementary capabilities:

• Grounding – understanding individual GUI components and linking them to semantics.
• Agent – planning and executing multi-step actions to complete user goals on Chinese Android apps.

See AgentCPM-GUI for more details.

🌟 Key Features

Aspect	Grounding	Agent
Objective	GUI widgets grounding / OCR text	Follow natural-language instructions to operate an app
Data	2 × JSONL files (cap.jsonl, ocr.jsonl) + screenshots	Per-episode JSON + step-level screenshots
Actions	n/a	Tap, long-tap, text-input, scroll, etc. (result_action_type, see here)

📑 Data Format

1. Agent episodes (CAGUI_agent/domestic/<episode_id>/<episode_id>.json)

Each file is a list of steps:

Field	Type	Description
episode_id	str	Unique id
episode_length	int	Total steps
step_id	int	Step index (0-based)
instruction	str	user goal
image_path	str	Relative path to screenshot
image_width / image_height	int	Raw resolution
ui_positions	str (JSON list)	Normalised [[y, x, h, w], …] UI element boxes
result_action_type	int	Action code, see here
result_action_text	str	Text typed (if any)
result_touch_yx / result_lift_yx	str	Normalised touch coords, [-1,-1] if no touch
duration	float | null	Action time (s)

2. Grounding annotations (cap.jsonl, ocr.jsonl)

One JSON object per line:

Field	Example	Description
task	"bbox2function" / "bbox2text"	Sub-task type
image	"grounding_eval/dataset/images/0.jpeg"	Screenshot path
id	0	Unique int id
abs_position	"<x1, y1, x2, y2>"	Pixel-level bbox
rel_position	"<x1, y1, x2, y2>"	Normalised bbox
text	"UI元素是一个菜单按钮…"	Target description / OCR string
