# surfPRM-data
SFT training data for **surfPRM**, a process reward model (PRM) for web agents.
- 9,821 pairwise step-preference samples stored as a single JSON array
- Each sample has one field `conversation` with `system` / `user` / `assistant` turns:
the user turn contains the task intent, the current page's accessibility tree
(AXTree), the previous action trajectory, the start/current URLs, and two candidate
next actions; the assistant turn contains structured
`<State>/<Criteria>/<Analysis>/<Answer>` reasoning ending in the preferred action
- The exact prompt template is documented in the model cards of the models trained
on this data: [surfPRM-qwen3.5-4b](https://huggingface.co/polowitty/surfPRM-qwen3.5-4b)
and [surfPRM-qwen3.5-9b](https://huggingface.co/polowitty/surfPRM-qwen3.5-9b)
