| # browser-world-models: WebArena reddit transitions | |
| Browser state transitions collected by running the **106 official WebArena reddit tasks** | |
| against a self-hosted, reproducible WebArena (Postmill) instance (rootless Apptainer on | |
| SLURM). Each row: before/after screenshots, the Set-of-Marks action between them, the task | |
| goal, and LLM-judge next-state labels in two target formats (free prose and a fixed | |
| CHANGED/NAV/CONTENT/UI/ERROR template). | |
| - ~726 transitions / 110 trajectories / 1 site (Postmill "reddit"), no-op rate ~0.49 | |
| - Labels: gpt-4o-mini judge from (before, action, after); simulator trains on (before, action) -> label | |
| - Pipeline + training/eval code: https://github.com/photomz/browser-world-models (PR #4) | |
| - Companion pilot set (live web, 44 sites): sudac/browser-world-models-transitions | |
| Collected 2026-06-10. Single-site reproducible complement to the live-web pilot set. | |
