CAGUI: Chinese Android GUI Benchmark

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

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

See AgentCPM-GUI for more details.


๐ŸŒŸ Key Features

Aspect Grounding Agent
Objective GUI widgets grounding / OCR text Follow natural-language instructions to operate an app
Data 2 ร— 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)

๐Ÿ“‘ 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], โ€ฆ] 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 "UIๅ…ƒ็ด ๆ˜ฏไธ€ไธช่œๅ•ๆŒ‰้’ฎโ€ฆ" Target description / OCR string
