ToyMaze2D Easy All-Step Future-Rollout COT
This dataset is generated from the local VisGym ToyMaze2D maze_2d/easy environment.
Rows:
train/: 500,000 gzip-compressed JSONL rows.test/: 100 gzip-compressed JSONL rows.
Each row is a full trajectory conversation. Every user turn stores a prompt and
one JPEG image item with image_prev, image, and image_next; image_prev == image
is validated for every step, and the final step has image_next == image.
Two non-stop move steps per trajectory contain four one-step future rollout
images (right, up, left, down) with loss=true. Other non-stop steps use
a fixed trivial thinking template. The final stop step uses a fixed stop COT and
outputs ('stop', 'stop').
Target Hub repo: https://huggingface.co/datasets/novastar112/toy_maze_2d_easy_allstep_thinking_future_rollout_cot_500k
Prompt step budget: 20 total steps for easy; the user prompt says max_steps - step_index - 1 remaining steps.
