ToyMaze2D Official VisGym Source All-Step Future-Rollout Natural COT

Source dataset: https://huggingface.co/datasets/VisGym/visgym_data/tree/main/toy_maze_2d/train

This dataset preserves the official VisGym ToyMaze2D training trajectory prompts, actions, image_prev, image, image_next, generated future-rollout images, and source step budget. Each row is an all-step user/assistant conversation with two selected move steps containing four one-step future rollout images each. Only the final text item of each selected rollout assistant turn was rewritten to use the natural_paragraph style. The key rollout thinking paragraphs avoid numeric remaining-distance mentions.

Records: 99899 Skipped official source records: 101 Generated rollout images: 799192 Key template id: toymaze_allstep_key_rollout_natural_v2
