| # cua-lite/LiteOS |
|
|
| LiteOS desktop-use agent rollout dataset. Train split is preserved from HaoranLiu/LiteOS; validation split is staged from .logs/rollout/lite.osworld_eval_g3 with model folder names matching train split configs. |
|
|
| ## Origin |
|
|
|
|
|
|
| ## Load via `datasets` |
|
|
| ```python |
| from datasets import load_dataset |
| |
| # entire dataset |
| ds = load_dataset("cua-lite/LiteOS") |
| |
| # just one named subset (config) |
| ds = load_dataset("cua-lite/LiteOS", "EvoCUA-8B-20260105") |
| ``` |
|
|
| You can also filter by `metadata.platform` / `metadata.task_type` / |
| `metadata.others.*` after loading; every row carries a rich `metadata` |
| struct (see schema below). |
|
|
| ## Schema |
|
|
| Each row has these columns: |
|
|
| | column | type | notes | |
| |---|---|---| |
| | `images` | list[Image] | embedded PNG/JPEG bytes; HF viewer renders thumbnails | |
| | `messages` | list[struct] | OpenAI-style turns with `role` + structured `content` | |
| | `metadata` | struct | `{platform, task_type, extra_tool_schemas, valid_actions, others{...}}` | |
|
|
| Coordinate values in `messages` are normalized to `[0, 1000]` integers. |
|
|
| **Image-dedup (`grounding.*` / `understanding` cohorts).** These cohorts are |
| single-image-per-row and many rows share the same screenshot, so to avoid |
| re-embedding identical image bytes once per instruction they are stored |
| *folded*: one row per unique screenshot (image embedded once), carrying an |
| extra **`_folded`** column — a JSON string with the authoritative list of |
| `{messages, metadata}` members for that screenshot. The row's top-level |
| `messages` is the members concatenated for viewer convenience. `use` |
| cohorts are not folded. **Use `lite.data.hf.download` to consume this repo** — |
| it unfolds automatically back to one row per instruction; reading the parquet |
| directly yields the folded form. |
|
|
| ## Layout |
|
|
| ``` |
| <platform>/<task_type>/<split>/shard-NNNNN-of-NNNNN.parquet # single-variant cohort |
| <platform>/<task_type>/<split>/<variant>/shard-NNNNN-of-NNNNN.parquet # multi-variant cohort |
| ``` |
|
|
| - `platform` ∈ {desktop, mobile, web} |
| - `task_type` ∈ {understanding, grounding.action, grounding.point, grounding.bbox, use} — used verbatim as the dir component |
| - HF config names are `<platform>.<task_type>` by default (e.g. `mobile.grounding.action`) — UNLESS the dataset was staged with `--config-names`, which sets verbatim, explicitly-chosen config names (see the `configs:` block above for the authoritative list). The agent registry lookup key in code is `<agent>@<platform>@<task_type>` (e.g. `qwen3_vl@mobile@grounding.action`); only this user-facing token uses `.` between platform and task_type, because `@` triggers a 403 on the dataset-viewer's signed image URLs. |
| - HF split names stay `train` / `validation` (the `datasets` library blacklists `<>:/\|?*` in split names; everything else is fine in config_name) |
| - `validation` is an in-distribution held-out slice (never used in training); `test` is reserved for out-of-distribution benchmark datasets |
|

| ## Local mirror & SFT export |
| |
| For local workflows (SFT export, dedup, mixing across datasets), use |
| `lite.data.hf.download` to mirror this repo back to the canonical local |
| layout: |
| |
| ``` |
| $CUA_LITE_DATASETS_ROOT/cua-lite/LiteOS/ |
| images/<hash[:2]>/<hash>.<ext> # content-addressed image store |
| <platform>/<task_type>/<split>[/<variant>].parquet # rows reference images by relative path |
| ``` |
| |
| Rows in the local parquet have `images: list[str]`; bytes are extracted to |
| the image store. `lite.train.export.export_sft` consumes the local |
| form directly with `--image-root=$CUA_LITE_DATASETS_ROOT`. |
| |
| - Total unique images: **632,354** |
| - Image store size: **285.91 GB** |
| |
