# CAGUI: **C**hinese **A**ndroid **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](https://github.com/OpenBMB/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](https://github.com/OpenBMB/AgentCPM-GUI/blob/main/eval/utils/action_type.py)) |

## 📑 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](https://github.com/OpenBMB/AgentCPM-GUI/blob/main/eval/utils/action_type.py) |
| `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 |
