| # OpenMobile-Data-v2 |
|
|
| Two parts. SFT is one decision step per example: the model reads the remaining screenshots and the conversation history, then writes a `Thought:` followed by one tool call. Coordinates belong in the tool arguments. The screen space in the prompt is **999×999**. RL is one task per line, with the instruction, the initial state, and the check for success. |
|
|
| SFT has **11,643** trajectories and **118,582** steps, about **59.2 GB**. Trajectory folders contain only `screenshot_step{K}.png`. RL has **2,475** tasks in one JSONL file. |
|
|
| ## Splits |
|
|
| | Split | File | Trajectories | Steps | Tools | |
| | --- | --- | ---: | ---: | --- | |
| | Emulator | `emulator/train.json` | 7,725 | 83,631 | `mobile_use` only. 3,202 cross-app, 4,523 single-app | |
| | Simulator, GUI-only | `simulator/gui-only/train.json` | 2,144 | 22,857 | `mobile_use` only | |
| | Simulator, hybrid | `simulator/hybrid/train.json` | 1,774 | 12,094 | `mobile_use`, plus extra app tools listed in the current tool message | |
|
|
| `dataset_info.json` registers these files as `emulator_qwen35_last3_noloop_notitle_nocoord_think_thought`, `mobilegym_qwen35_last3_noloop_notitle_nocoord_think_thought`, and `gui_mcp_qwen35_last3_noloop_notitle_nocoord_think_thought`. |
|
|
| ## Record format |
|
|
| Each `train.json` is a list of objects with `id`, `messages`, and `images`. |
|
|
| - `images` holds at most the last three screenshots, oldest first. Paths are relative to that JSON file. |
| - Earlier screenshots are replaced in the text by `This screenshot has been collapsed.` The remaining `<image>` placeholders line up with `images`. |
| - History `assistant` turns are marked `"loss": false`. Supervise the last `assistant` turn. |
| - Hybrid `tool` messages may include a foreground-app tool catalog. Those tools are valid only while that app stays in front. |
|
|
| ## RL tasks |
|
|
| `RL/tasks.jsonl` is one JSON object per line. Each line has `task`, `init`, and `verify` together. |
|
|
| - `task.instruction` is the user goal. `task.apps` lists the apps involved. |
| - `init` is the starting state, including `assertion_initials`. |
| - `verify` is the success check: `assertions` and optional `extra_checks`. |
|
|
| ## Use with ms-swift |
|
|
| Download the full repository so the screenshot paths resolve. The dataset viewer table stores those paths as strings and does not replace this download. |
|
|
| ```bash |
| hf download OpenMobile-2/OpenMobile-Data-v2 --repo-type dataset --local-dir OpenMobile-Data-v2 |
| |
| swift sft \ |
| --custom_dataset_info OpenMobile-Data-v2/dataset_info.json \ |
| --dataset emulator_qwen35_last3_noloop_notitle_nocoord_think_thought \ |
| mobilegym_qwen35_last3_noloop_notitle_nocoord_think_thought \ |
| gui_mcp_qwen35_last3_noloop_notitle_nocoord_think_thought |
| ``` |
|
|
| Adjust `model`, batch size, and output paths for your local [ms-swift](https://github.com/modelscope/ms-swift) setup and hardware. |
