GUI-Owl AndroidWorld SFT Mix — TARGETED / in-domain

Purpose: AndroidWorld (116-task) SFT for a GUI-Owl-1.5-2B block-diffusion VLA. This dataset is an action-balanced, source-mixed SFT corpus assembled from five Android GUI-agent trajectory sources. It is built for in-domain supervised fine-tuning ahead of RL. The mix deliberately includes AndroidWorld task-family coverage (via the openmobile anchor, whose app field holds AW task-family names) and accepts in-domain overlap by design.

This version: TARGETED

In-domain-heavy mix (450k steps). openmobile up-sampled to ~37% (the AndroidWorld anchor) plus gui_odyssey ~26% for long-horizon chaining and minimal AITW ~14%. High scarce-verb floors via replication (open 10%, terminate 13%). Fastest path to AndroidWorld mastery.

• Total steps: 450,000
• Shards: 113 parquet files (balanced-*.parquet, ~4000 rows each)
• Build seed: 7

Action distribution

action	rows	share
click	202,500	45.0%
type	67,500	15.0%
terminate	58,500	13.0%
open	45,000	10.0%
swipe	36,000	8.0%
system_button	17,456	3.88%
long_press	9,149	2.03%
wait	7,839	1.74%
answer	6,056	1.35%

Source mix

source	rows	share
openmobile	168,605	37.47%
gui_odyssey	119,000	26.44%
androidcontrol_par	63,395	14.09%
aitw	63,000	14.0%
amex	36,000	8.0%

Swipe direction (overall)

dir	rows	share
up	19,937	55.38%
down	9,235	25.65%
left	3,576	9.93%
right	3,252	9.03%

Note: a direction-balanced swipe subset (up40/down30/left17/right13) is enforced up to 19,069 swipes; the remainder keeps the natural (up-heavy) distribution as ballast, so the overall swipe split above is up-heavy by design.

Schema (unified 13-column)

source           string   # origin dataset: androidcontrol_par | amex | openmobile | gui_odyssey | aitw
src_key          string   # original sample key in the source corpus
app              string   # app / AndroidWorld task-family label (may be empty)
instruction      string   # natural-language goal for the episode
history          string   # prior-step context
screenshot       binary   # PNG/JPEG screen bytes
screen_width     int
screen_height    int
episode_id       string
target_json      string   # ground-truth action as JSON (canonical label)
action_type      string   # parsed action: click|type|swipe|system_button|terminate|wait|open|long_press|answer
coordinate       list     # parsed primary coordinate (normalized 0-1000) or null
coordinate2      list     # parsed secondary coordinate (swipe end) or null

Coordinates are normalized to a 0-1000 grid (origin top-left).

How the mix was built

Balanced via a parallel 2-stage builder (build_balanced_mix.py): actions and coordinates are parsed from target_json, then per-action keep_prob, per-(action, coordinate-bin) caps (max_frac_per_coordbin = 0.06, 8x8 grid), and per-(action, app) caps (max_frac_per_app = 0.22) are applied. Scarce AndroidWorld verbs (open / answer / long_press / terminate) are up-weighted via sampling-with-replacement (replication caps: {'open': 10, 'answer': 8, 'long_press': 8, 'terminate': 5}). Full provenance and exact targets are in balance_report.json.
