A Very Big Video Reasoning Suite
We bet on a future that video reasoning is the next fundamental intelligence paradigm, after language reasoning, where spatiotemporal embodied world experiences could be more naturally captured.
hit_target_after_bounce
GitHub
Prompt
The scene shows a ball with an arrow indicating its initial direction, and several empty target positions (hollow circles) on the right side. Simulate the ball moving along this direction and bouncing off walls following the law of reflection (the angle of reflection equals the angle of incidence). The ball will follow a complete trajectory and eventually align exactly with and completely overlap one of the target positions.

sequence_completion
GitHub
Prompt
The scene shows a color_cycle sequence. Elements are arranged horizontally from left to right. The last position contains a question mark (?) indicating a missing element. Observe the pattern: the colors follow a cyclic order that repeats after a certain number of elements. Determine the element that should replace the question mark to complete the sequence according to the established pattern.

grid_avoid_red_block
GitHub
Prompt
The scene shows a 10x10 grid with a blue start square (containing a yellow circular agent), a green end square, and multiple red filled rectangles indicating obstacles. Starting from the blue start square, the agent can move to adjacent cells (up, down, left, right). The goal is to move the agent to the green end square along the shortest path without entering any cells containing red filled rectangles.
