Maze 17x17 500k — Shortest Path

Supervised fine-tuning corpus of 17x17 mazes where the target trajectory is the unique shortest path from START to GOAL. Mazes are generated with Prim's algorithm so there is a single solution path.

Splits and configs

train: 450,000 examples
test: 512 examples

Three reward configurations are provided — they share the same prompts but differ in the reward-model metadata used by downstream RL:

config	reward signal
`binary`	1 if the path reaches the goal, else 0
`continuous`	fractional progress toward the goal
`distance`	goal reached + solution-quality component

Schema

Each row has columns: data_source, prompt, ability, reward_model, extra_info. prompt is a chat-formatted list of messages whose user turn contains the maze grid in a tokenized form (WALL, PATH, START, GOAL, NEWLINE). The target trajectory lives in extra_info.answer and reward_model.ground_truth.

Usage

from datasets import load_dataset

ds = load_dataset("stablegradients/maze-17x17-500k-shortest", "binary")
print(ds["train"][0])
